（php获取内容）我如何使用foreach循环去除检索一个字符串

Question

I'm trying to get content of some table from url but it always gets one string.

I was wondering if I could use foreach loop to get all strings which is in the table like:

<?php
$url = 'https://www.w3.org/WAI/UA/2002/06/thead-test';
$content = file_get_contents($url);
$first_step = explode( '<td>' , $content );
$second_step = explode('</td>' , $first_step[1] );
$output = $second_step[0];
echo $output;
?>

I found some link after some research, but it couldn't help me that much.

Any help is appreciated :)

Not completely clear what you what here... you want to get the content of all the strings between table cells (<td>xxx</td>)?

$url = 'https://www.w3.org/WAI/UA/2002/06/thead-test';
$content = file_get_contents($url);
preg_match_all('#<td>(.*?)</td>#m', $content, $matches);
$output = $matches[1];
var_dump($output);
