Question

如果我们的字符串变量如下：

$str = "This is test text and I'd like to split it";

如何让它在foreach或for循环中将每个特定单词打印为数组项，因此数组看起来像（[0] =＆gt; This，[1] =＆gt;是...）

谢谢！

您可以使用explode()功能，如下所示：

<?php

    $str = "This is test text and I'd like to split it";

    $array = explode(" ", $str);

    foreach($array as $key => $value){
        echo $key . " => " . $value . "<br />";
    }

?>

输出：

0 => This
1 => is
2 => test
3 => text
4 => and
5 => I'd
6 => like
7 => to
8 => split
9 => it

如果您只想打印一定数量的元素，请使用for代替foreach。

<?php

    $str = "This is test text and I'd like to split it";

    $array = explode(" ", $str);

    for($i = 0; $i < 3; ++$i){
        echo $i . "=>" . $array[$i] . "<br />";
    }

?>

输出：

0=>This
1=>is
2=>test

将长字符串转换为数组和索引
