用于制作 slug 的 PHP 函数（URL 字符串）

Question

我想要一个从 Unicode 字符串创建 slugs 的函数，例如 gen_slug('Andrés Cortez') 应该返回 andres-cortez。我该怎么做呢？

Answer 1

在我的本地主机上一切正常，但在服务器上它帮助我在“mb_strtolower”处“set_locale”和“utf-8”。

<?
setlocale( LC_ALL, "en_US.UTF8" );
function slug( $str, $char = "-", $tf = "lowercase" )
{
    $str = iconv( "utf-8", "us-ascii//translit//ignore", $str ); // transliterate
    $str = str_replace( "'", "", $str ); // remove “'” generated by iconv
    $str = preg_replace( "~[^a-z0-9]+~ui", $char, $str ); // replace unwanted by single “-”
    $str = trim( $str, $char ); // trim “-”
    if( $tf == "lowercase" ) $str = mb_strtolower( $str, "utf-8" ); // lowercase
    elseif( $tf == "uppercase" ) $str = mb_strtoupper( $str, "utf-8" );
    return $str;
}
?>

测试

$string = "--+ě

Answer 2

对于标准的字母数字英语 - 没什么复杂的。

/**
 * Update the provided string to a slug-safe format.
 *
 * @param string $string
 * @return string
 */
function slugify($string)
{
    return strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $string), '-'));
}

Answer 3

不确定它是否适用于所有情况，但我从 Laravel Str 类 并添加了 iconv('utf-8', 'us-ascii//TRANSLIT', $title) 来处理重音符号，而无需使用 voku/portable-ascii 它似乎工作得很好对于我的用例：

    public static function slug($title, $separator = '-')
    {
        $title = iconv('utf-8', 'us-ascii//TRANSLIT', $title);
        $flip = $separator === '-' ? '_' : '-';
        $title = preg_replace('!['.preg_quote($flip).']+!u', $separator, $title);
        // Replace @ with the word 'at'
        $title = str_replace('@', $separator.'at'.$separator, $title);
        // Remove all characters that are not the separator, letters, numbers, or whitespace.
        $title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', mb_strtolower($title, 'UTF-8'));
        // Replace all separator characters and whitespace by a single separator
        $title = preg_replace('!['.preg_quote($separator).'\s]+!u', $separator, $title);

        return trim($title, $separator);
    }

Answer 4

在 Laravel 8 中是：

Str::slug('Hola como te va', '-');

// hola-como-te-va

Answer 5

在我看来，使用 Transliterator::transliterate 的选项是它可以提供最佳结果（从任何字母表转换），它非常可定制，代码很短并且不需要外部库。

但是使用 hdogan 的有价值的答案中的规则，在某些情况下会返回不正确的结果：

• 删除数字之间的连字符：年2020-2024 -> years-20202024，预期结果：years-2020-2024。
• 删除字符（如下划线）而不是将其转换为连字符：The_word -> theword，预期结果：the-word。
• 在某些情况下，它会在开头或结尾留下连字符： my string -> -my-string-，预期结果：my-string。
• 不转换或删除所有非字母数字字符：Test © -> test-©，预期结果：test-c 或 test （就我而言，我更喜欢第一个）。
• 它不会标准化或删除其他字母变体：Nº 1 -> n°-1，预期结果：no-1 或 n-1。

根据该回复，我对规则进行了一些更改：

$string = ' Namnet på bildtävlingen nº1@2020-`24...like&share';

$slug = \Transliterator::createFromRules("
    :: Any-Latin;
    :: NFD;
    :: [:Mn:] Remove;
    :: NFKC;
    :: Latin-ASCII;
    :: Lower();
    ^[^[:Ll:][:Nd:]]+ > ;
    [^[:Ll:][:Nd:]]+$ > ;
    [^[:Ll:][:Nd:]]+ > '-';
")->transliterate($string);

$slug = preg_replace(['/[^a-z0-9-]+/', '/^-+|(?<=-)-+|-+$/'], '', $slug);

echo $slug; // namnet-pa-bildtavlingen-no1-2020-24-like-share
// previous result: -namnet-pa-bildtavlingen-nº12020`24likeshare

更改说明：

• 将 NFC 更改为 NFKC，因为它标准化了更多字符（ª -> a 等）。
• 添加了 Latin-ASCII 以将更多字符转换为字母数字（® -> r 等）。
• 开头和结尾的所有非字母数字字符都将被删除。
• 所有非字母数字字符（不仅是 [-[:Separator:]]）都将转换为连字符。

使用 preg_replace 是因为某些西里尔字符（例如 г）由于某种原因未标准化，而我们只想要带有连字符的字母数字结果，因此我们删除了这几个例外。我还没有设法在规则中规范它们，如果有人知道是否可能，我们将不胜感激。

Answer 6

自 gTLD 和 IDN 的使用越来越广泛，我不明白为什么 URL 不应包含 Andrés。

只需对您想要的 $URL 进行 rawurlencode 即可。大多数浏览器在 URL 中显示 UTF-8 字符（可能不是某些古老的 IE6），如果需要用于广告目的或只是将其写入广告，则可以使用 bit.ly / goo.gl 在俄语和阿拉伯语等情况下使其简短就像用户将它们写在浏览器 URL 上一样。

唯一的区别是空格“ ”，如果您不想允许这些空格，则用“-”和“/”替换它们可能是个好主意。

<?php
function slugify($url)
{
    $url = trim($url);

    $url = str_replace(" ","-",$url);
    $url = str_replace("/","-slash-",$url);
    $url = rawurlencode($url);
}
?>

编码后的 URL

Answer 7

因为我在这里看到了很多方法，但我为自己找到了一个最简单的方法。也许它会对某人有所帮助。

$slug = strtolower(preg_replace('/[^a-zA-Z0-9\-]/', '',preg_replace('/\s+/', '-', $string) ));

Answer 8

这是制作鼻涕虫的简短而简单的解决方案

function convertURLs($value){
$delimiter = '-';
$slug = strtolower(trim(preg_replace('/[\s-]+/', $delimiter, preg_replace('/[^A-Za-z0-9-]+/', $delimiter, preg_replace('/[&]/', 'and', preg_replace('/[\']/', '', iconv('UTF-8', 'ASCII//TRANSLIT', $value))))), $delimiter));
return $slug;}

Answer 9

我正在使用这个函数并且它工作正常：

function slugify($string) {
  return strtolower(trim(preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1', htmlentities($string, ENT_QUOTES, 'UTF-8')), ENT_QUOTES, 'UTF-8')), '-'));
}

Answer 10

尝试使用 urldecode 来获取解码后的字符串：

echo urldecode('%D8%A7%D9%84%D8%B3%D9%84%D8%A7%D9%85-%D8%B9%D9%84%DB%8C%DA%A9'); 

// return السلام-علیک

Answer 11

对我来说，这个变体是完美的，还将 & 更改为 and。这是代码：

function dSlug($string) {
    return strtolower(trim(preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1',htmlentities(preg_replace('/[&]/', ' and ', $title), ENT_QUOTES, 'UTF-8')), ENT_QUOTES, 'UTF-8')), '-'));
}`

Answer 12

与其进行冗长的替换，不如尝试这个：

public static function slugify($text, string $divider = '-')
{
  // replace non letter or digits by divider
  $text = preg_replace('~[^\pL\d]+~u', $divider, $text);

  // transliterate
  $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);

  // remove unwanted characters
  $text = preg_replace('~[^-\w]+~', '', $text);

  // trim
  $text = trim($text, $divider);

  // remove duplicate divider
  $text = preg_replace('~-+~', $divider, $text);

  // lowercase
  $text = strtolower($text);

  if (empty($text)) {
    return 'n-a';
  }

  return $text;
}

这是基于 Symfony 的 Jobeet 教程中的一个。

Answer 13

更新

由于这个答案引起了一些关注，我添加了一些解释。

所提供的解决方案将基本上取代除 AZ、az、0-9 和 & 之外的所有内容。 -（连字符）与 -（连字符）。因此，它无法与其他 unicode 字符（这些字符是 URL slug/字符串的有效字符）一起正常工作。一种常见的情况是输入字符串包含非英语字符。

仅当您确信输入字符串不会包含您可能希望成为输出/slug 一部分的 unicode 字符时，才使用此解决方案。

例如。 “नारी शक्ति”将变成“----------”（全是连字符）而不是“नारी-शक्ति”（有效的 URL slug）。

回答

$slug = strtolower(trim(preg_replace('/[^A-Za-z0-9-]+/', '-', $string)));

Answer 14

如果您安装了 intl 扩展，则可以使用 Transliterator::transliterate 函数可以轻松创建 slug。

$string = 'Namnet på bildtävlingen';

$rules = <<<'RULES'
    :: Any-Latin;
    :: NFD;
    :: [:Nonspacing Mark:] Remove;
    :: NFC;
    :: [^-[:^Punctuation:]] Remove;
    :: Lower();
    [:^L:] { [-] > ;
    [-] } [:^L:] > ;
    [-[:Separator:]]+ > '-';
RULES;

$slug = \Transliterator::createFromRules($rules)
    ->transliterate( $string );

echo $slug; // namnet-pa-bildtavlingen

演示

请注意，该解决方案适用于任何字母表，并且高度灵活。

Answer 15

注意：我从 WordPress 中获取了这个并且它有效！

像这样使用它：

echo sanitize('testing this link');

代码

//taken from wordpress
function utf8_uri_encode( $utf8_string, $length = 0 ) {
    $unicode = '';
    $values = array();
    $num_octets = 1;

    $string_length = strlen( $utf8_string );
    for ($i = 0; $i < $string_length; $i++ ) {

        $value = ord( $utf8_string[ $i ] );

        if ( $value < 128 ) {
            if ( $length && ( $unicode_length >= $length ) )

Answer 16

使用许多高级开发人员支持的现有解决方案始终是一个好主意。最流行的是 https://github.com/cocur/slugify。首先，它支持多种语言，并且正在更新。

如果您不想使用整个包，可以复制您需要的部分。

这是另一种，例如“带有奇怪字符的标题 ééé AX Z”变为“带有奇怪字符的标题-eee-axz”。

Answer 19

这里已经有很多答案了，所以我几乎不想添加另一个答案，但是没有一个函数可以完成我需要的一切。

对我来说最好的基础是第 3 号函数，其中比较了它们的速度。我添加/修复了一些替换，因此

1. ' 被删除，
2. . 被 - 替换，
3. α 被替换为a、
4. ẞ 替换为 b、
5. Ł （及类似）替换为 L 代替 K，
6. € 和 $ 符号替换为 eur 和 usd 分别（根据需要添加更多）。

您可以选择添加 '&' => '-and-'，但 SEO 建议不要使用连词 (#8），所以我将其保留在我的用例中。 （不过，此函数不会从字符串中删除现有的 and 和 or）

我还添加了一行代码来修复双破折号在我想出的这个奇怪的字符串中，以及一个可选参数来限制 slug 的长度。

代码

<?php
function slugify($text, $length = null)

不要为此使用 preg_replace。有一个专门为该任务构建的 php 函数：strtr()
http://php.net/manual/en/function.strtr.php

取自上面链接中的评论（我自己测试过；它有效：

function normalize ($string) {
    $table = array(
        'Š'=>'S', 'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',
        'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
        'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
        'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
        'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',

Answer 23

我正在使用：

function slugify($text)
{ 
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    return strtolower(preg_replace('/[^A-Za-z0-9-]+/', '-', $text));
}

唯一的后备方案是西里尔字符不会被转换，我现在正在寻找对于每个西里尔字符不长 str_replace 的解决方案。

Answer 24

我认为最优雅的方式是使用 Behat\Transliterator\Transliterator。

我需要通过你的类扩展这个类，因为它是一个抽象，有些像这样：

<?php
use Behat\Transliterator\Transliterator;

class Urlizer extends Transliterator
{
}

然后，只需使用它：

$text = "Master Ápiu";
$urlizer = new Urlizer();
$slug = $urlizer->transliterate($slug, "-");
echo $slug; // master-apiu

当然你也应该把这些东西放在你的作曲家中。

composer require behat/transliterator

这或许也是一种方法。受到这些链接的启发 专家交换和alinalexander

function slugifier($txt){

   /* Get rid of accented characters */

   $replace = explode(",","c,ae,oe,a,e,i,o,u,a,e,i,o,u,a,e,i,o,u,y,a,e,i,o,u,a,e,i,o,u");
   $txt = str_replace($search, $replace, $txt);

   /* Lowercase all the characters */
   $txt = strtolower($txt);

   /* Avoid whitespace at the beginning and the ending */
   $txt = trim($txt);

   /* Replace all the characters that are not in a-z or 0-9 by a hyphen */
   $txt = preg_replace("/[^a-z0-9]/", "-", $txt);
   /* Remove hyphen anywhere it's more than one */
   $txt = preg_replace("/[\-]+/", '-', $txt);
   return $txt;   
}

Answer 26

function slugify($text)
{
    // replace non letter or digits by -
    $text = preg_replace('~[^\pL\d]+~u', '-', $text);
    // transliterate
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    // remove unwanted characters
    $text = preg_replace('~[^-\w]+~', '', $text);
    // trim
    $text = trim($text, '-');
    // remove duplicate -
    $text = preg_replace('~-+~', '-', $text);
    // lowercase
    $text = strtolower($text);
    if (empty($text)) {
        return 'n-a';
    }
    return $text;
}

用例：

echo slugify('bu metinde ç ö ş ğ ü ı * # karakter $ @ ! ?  kullanılamaz');

输出：bu-metinde-cosgui-karakter-kullanilamaz

您可以查看 Normalizer::normalize()，

Answer 28

使用 Core 中已经实现的东西怎么样？

//Clean non UTF-8 characters    
Mage::getHelper('core/string')->cleanString($str)

或者核心 url/ url 重写方法之一..

Answer 29

我根据 Maerlyn 的回复写了这篇文章。无论页面上的字符编码如何，此功能都将起作用。它也不会将单引号变成破折号:)

function slugify ($string) {
    $string = utf8_encode($string);
    $string = iconv('UTF-8', 'ASCII//TRANSLIT', $string);   
    $string = preg_replace('/[^a-z0-9- ]/i', '', $string);
    $string = str_replace(' ', '-', $string);
    $string = trim($string, '-');
    $string = strtolower($string);

    if (empty($string)) {
        return 'n-a';
    }

    return $string;
}

Answer 30

这里有一个很好的解决方案，它也可以处理特殊字符。

Texto Fantástico => texto-fantastico

function slugify( $string, $separator = '-' ) {
    $accents_regex = '~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i';
    $special_cases = array( '&' => 'and', "'" => '');
    $string = mb_strtolower( trim( $string ), 'UTF-8' );
    $string = str_replace( array_keys($special_cases), array_values( $special_cases), $string );
    $string = preg_replace( $accents_regex, '$1', htmlentities( $string, ENT_QUOTES, 'UTF-8' ) );
    $string = preg_replace("/[^a-z0-9]/u", "$separator", $string);
    $string = preg_replace("/[$separator]+/u", "$separator", $string);
    return $string;
}
