从字符串中提取参数的最佳方法

发布于 2024-12-05 19:52:45 字数 290 浏览 0 评论 0原文

我有一个 name="value" 类型字符串，看起来像...

{user type="active" name="james green" id="45" group="active users"}

我需要一个通用函数来解析这种类型的字符串，从这种格式中提取所有名称/值对作为数组（始终用双引号括起来，每个参数都用空格分隔，括在 {} 中）以及初始开头词（在本例中为 user）。

任何想法将不胜感激。

I have a name="value" type string that looks like...

{user type="active" name="james green" id="45" group="active users"}

I need a generic function that will parse this type of string extracting all of the name/value pairs as an array from this format (always within double quotes and each param sepertated by a space, enclosed in {}) as well as the initial opening word (user in this case).

Any ideas would be much appreciated.

基本上

 preg_match_all('~(\w+)="(.+?)"~', $string, $matches, PREG_SET_ORDER);
 foreach($matches as $m)
     $array[$m[1]] = $m[2]

basically

 preg_match_all('~(\w+)="(.+?)"~', $string, $matches, PREG_SET_ORDER);
 foreach($matches as $m)
     $array[$m[1]] = $m[2]

$string = '{user type="active" name="james green" id="45" group="active users"}';
$user = simplexml_load_string('<' . substr($string, 1, -1) .'/>');
print_r(current($user));

。

Array
(
    [type] => active
    [name] => james green
    [id] => 45
    [group] => active users
)

但这应该很容易并且更适合使用正则表达式来解决

$string = '{user type="active" name="james green" id="45" group="active users"}';
$user = simplexml_load_string('<' . substr($string, 1, -1) .'/>');
print_r(current($user));

will give

Array
(
    [type] => active
    [name] => james green
    [id] => 45
    [group] => active users
)

But that should be easy and more appropriate to solve with a Regex.

名字“james green”可以这样提取

<?php
    $point=strpos( $string, 'name="' ) + strlen('name="');
    $string = substr($string,$point);

    $point=strpos( $string, '"' );
    $string = substr($string,$point);

    echo $string; // james green
?>

name "james green" can be extracted like this

<?php
    $point=strpos( $string, 'name="' ) + strlen('name="');
    $string = substr($string,$point);

    $point=strpos( $string, '"' );
    $string = substr($string,$point);

    echo $string; // james green
?>

$string = '{user type="active" name="james green" id="45" group="active users"}';
$string = str_replace('{', '', $string); // delete brackets
$array = explode(' ', $string);

$var = array_shift($array); // <-- here is 'user'

foreach($array as $pair)
{
$arr = explode('=', $pair);
$arr[0]; // <-- here is the key
$arr[1]; // <-- here is the value
}

未测试！
