大字符串到漂亮的数组

发布于 2024-12-21 04:49:28 字数 588 浏览 1 评论 0原文

我需要将大字符串变成一个漂亮的数组。字符串本身是标签和标签 ID 的列表。它们可以有任意数量。以下是字符串示例：29:funny,30:humor,2:lol - id:tag_name。现在，我在将其转换为数组时遇到问题 - Array ( [29] => fun [30] => humour )。我可以到达标签所在的部分

数组（
<块引用>
[0] = 数组 (
<块引用>
[0] = 29
[1] = 有趣
)
[1] = 数组 (
<块引用>
[0] = 30
[1]=幽默
)
)

我也研究过数组函数，但似乎它们都不能帮助我。有人可以帮我吗？

下面是一些帮助您继续操作的代码：

$str = "29:funny,30:humor,2:lol";
$arr = array();
foreach (explode(',', $str) as $v) {
    list($key, $val) = explode(':', $v);
    $arr[$key] = $val;
}
print_r($arr);
/* will output:
Array
(
    [29] => funny
    [30] => humor
    [2] => lol
)
*/

例如，您可以将 foreach 替换为 array_map ，但我认为这种方式对您来说更简单。

这是它的工作示例： http://codepad.org/4BpnCiEJ

Here's some code to get you going:

$str = "29:funny,30:humor,2:lol";
$arr = array();
foreach (explode(',', $str) as $v) {
    list($key, $val) = explode(':', $v);
    $arr[$key] = $val;
}
print_r($arr);
/* will output:
Array
(
    [29] => funny
    [30] => humor
    [2] => lol
)
*/

You could replace the foreach with an array_map for example, but I think it's simpler for you this way.

您可以使用explode() 来执行此操作，尽管这需要两次传递。第一个将字符串拆分为配对（explode (',', $string)），第二个将每个配对拆分

$arr = explode (',', $string);
foreach ($arr as &$pairing)
{
    $pairing = explode (':', $pairing);
}

You could use explode() to do this, though it would take two passes. The first to split the string into pairings (explode (',', $string)) and the second to split each paring

$arr = explode (',', $string);
foreach ($arr as &$pairing)
{
    $pairing = explode (':', $pairing);
}

$string = '29:funny,30:humor,2:lol';
$arr1   = explode(',', $string);
$result = array();
foreach ($arr1 as $element1) {
    $result[]  = explode(':', $element1);
}
print_r($result);

$string = '29:funny,30:humor,2:lol';
$arr1   = explode(',', $string);
$result = array();
foreach ($arr1 as $element1) {
    $result[]  = explode(':', $element1);
}
print_r($result);

您可以使用 preg_match_all

preg_match_all('#([\d]+):([a-zA-Z0-9]+)#', $sString, $aMatches);

// Combine the keys with the values.
$aArray = array_combine($aMatches[1], $aMatches[2]);

echo "<pre>";
print_r($aArray);
echo "</pre>";

输出：

Array
(
    [29] => funny
    [30] => humor
    [2] => lol
)

<?php

$tmp_array = explode(',', $test);

$tag_array = ARRAY();

foreach ($tmp_array AS $value) {
    $pair = explode(':', $value);
    $tag_array[$pair[0]] = $pair[1];
}

var_dump($tag_array);
