PHP:用两个 foreach 循环分解两个分隔符 - PHP: Explode two delimiters with two foreach loop

PHP: Explode two delimiters with two foreach loop

我试图通过爆炸两个分隔符<>和"'n"来获得两个foreach循环，但得到错误。 Warning: Invalid argument supplied for foreach()

这是我的代码

<?php
    $specifications = $scooter_meta->get_the_value('specifications');
    $titles = explode('<>', $specifications);
    $descs = explode("'n", $specifications);
    echo '<dl>';
    foreach($titles as $title => $descs){
        echo '<dt>' . $title . '</dt>';
        foreach($descs as $desc){
            echo '<dd>' . $desc . '</dd>';
        }
    }
    echo '</dl>';
?>

输入文本区域的值如下所示Title here<>this is the first scooter ever made. Title here 2<>another line for specification实际上我想让它像<title 1> here detail text

多谢

实际上你应该做这样的事情

<?php
$specifications = $scooter_meta->get_the_value('specifications');
$descs = explode("'n", $specifications);
echo '<dl>';
foreach($descs as $desc){
    $title = explode('<>', $desc);
    echo '<dt>' . $title[0] . '</dt>';
    for($i=1; $i<=count($title); $i++){
        echo '<dd>' . $title[$i] . '</dd>';
    }
}
echo '</dl>';
?>

$descs 变量不是数组，因为第一个 foreach 循环设置$descs 。

请参阅此行：

foreach($titles as $title => $descs){

$specifications = $scooter_meta->get_the_value('specifications');
$titles = explode('<>', $specifications);
echo '<dl>';
foreach($titles as $title => $descs){
    echo '<dt>' . $title . '</dt>';
    $descs = explode("'n", $descs);
    foreach($descs as $desc){
        echo '<dd>' . $desc . '</dd>';
    }
}
echo '</dl>';
