preg_match不使用strip_tags生成的变量

Question

I've read a few possible duplicate questions, but I don't think they address this problem. 我已经阅读了一些可能的重复问题，但我不认为它们可以解决这个问题。

In the below test code, the 4th preg_match does not work. 在下面的测试代码中，第4个preg_match不起作用。 It does, however, work if you un-comment the third line and use the text which what I copied and pasted from the echo. 但是，如果您取消注释第三行并使用我从回声中复制和粘贴的文本，它确实有效。

<?php
$html = file_get_contents('testhtml.txt');
$text = strip_tags($html);
//$text = 'body{font-family: arial,helvetica,sans-serif;} a{color: #06c;} p{margin:0;} #message{width:600px;margin:0 auto;} .legal{margin-top:2em;} .footer{margin-top:1em;padding:5px;background:#999999;color:#fff;} .footer a{color:#fff;} .senderName,.label{font-weight:bold;} .link,.label,.hint{margin-top: 20px;} .header-separator{height:4px;background-color:#e4002b;width:100%;margin-top:17px;} tr,td{vertical-align:top;text-align:left;} img{border:0;} Property id: 416848282 Property address: 12/41 Fake Road, Town, Vic 3000 Property URL: http://myurl.comu User Details: Name: Warren Warren Email: warren@warren.com.au Phone: (03) 1234 7777 I would like to: Lorem ipsum dolor sit amet, consectetur adipiscing elit.

echo $text . '<br /><br />';

$re = '/(?<=Name: )(.*?)(?= Email:)/s';
preg_match($re, $text, $matches);
print_r($matches);
echo '<br/>';

$re = '/(?<=Email: )(.*?)(?= Phone:)/s';
preg_match($re, $text, $matches);
print_r($matches);
echo '<br/>';

$re = '/(?<=Phone: )(.*?)(?= I would like to:)/s';
preg_match($re, $text, $matches);
print_r($matches);
echo '<br/>';

$re = '/(?<=I would like to: )(.*?)(?=Comments:)/s';
preg_match($re, $text, $matches);
print_r($matches);
echo '<br/>';

$re = '/(?<=Comments: )(.*?)(?= Remember, you can)/s';
preg_match($re, $text, $matches);
print_r($matches);
echo '<br/>';


?>

The contents of testhtml.txt is below. testhtml.txt的内容如下。 I'm wondering if the line breaks after "I would like to:" are causing problems, but I've also tried preg_replace( "/\\r|\\n/", "", $text ); 我想知道在“我想：”之后线路是否会导致问题，但我也尝试了preg_replace( "/\\r|\\n/", "", $text ); to clear it up first with no luck. 首先清除它，没有运气。

My question is: why is this not working and/or what is the difference between the two versions of $text? 我的问题是：为什么这不起作用和/或两个版本的$ text之间有什么区别？

The issue was that strip_tags still left me with a lot of line breaks even though these weren't shown when echoing. 问题是strip_tags仍然给我留下了很多换行符，即使strip_tags时没有显示这些换行符。 I found this by doing echo "<pre>" . $text . '</pre>'; 我通过echo "<pre>" . $text . '</pre>';找到了这个echo "<pre>" . $text . '</pre>'; echo "<pre>" . $text . '</pre>';

Thus my solution to work the expressions given was to simply add $text = preg_replace( "/\\r|\\n/", "", $text ); 因此，我使用给出的表达式的解决方案是简单地添加$text = preg_replace( "/\\r|\\n/", "", $text ); to remove all the line breaks. 删除所有换行符。
