Question

我已经阅读了一些可能的重复问题，但我认为他们没有解决这个问题。

在下面的测试代码中，第4个preg_match不起作用。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/>';


?>

testhtml.txt的内容如下。我想知道在“我想：”之后线路是否会出现问题，但我也尝试preg_replace( "/\r|\n/", "", $text );首先清除它而没有运气。

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？

<html>
<head>
<style type='text/css'>
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;}

</style>

Answer 1

问题是strip_tags仍然留下了很多换行符，即使这些换行时没有显示。我通过echo "<pre>" . $text . '</pre>';

找到了这个

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 );以删除所有换行符。

preg_match不使用strip_tags生成的变量
