Php使用strip_tags忽略<a>标签中的文本

问题描述：

I want to strip tags. When I use

$ta=strip_tags($_REQUEST['textarea'],'<a>');

it returns <a> tags. If I use

$ta=strip_tags($_REQUEST['textarea']);

it includes the interior of the <a href>.

I want only text. For example with this html

$text= '<p>test paragraph.</p>'<a href="index.php">Click link</a>';

I want only test paragraph, but I'm getting test paragraph.Click link

Thanks for your help

我想剥离标签。当我使用 p>

  $ ta = strip_tags（$ _ REQUEST ['textarea']，'＆lt; a＆gt;'）; 
  code>  pre> \  n 
 它返回＆lt; a＆gt;  code>标签。  
如果我使用 p> 
 
 
  $ ta = strip_tags（$ _ REQUEST ['textarea']）; 
  code>  pre> 
 
 它 包括＆lt; a href＆gt;  code>的内部。   p> 
 
 
我只想要文字。 例如，使用此html  p> 
 
 

  $ text ='＆lt; p＆gt;测试段落。＆lt; / p＆gt;'＆lt; a href =“index.php”＆gt;点击链接＆lt;  ; / a＆gt;'; 
  code>  pre> 
 
 我只想要测试段落 code>，但我得到测试段落。点击链接  p> 
 
 
感谢您的帮助 p>

If it's only <a href tags you don't like as commented in the comments above this should clear them away and leave you with the rest that can be easily removed with strip_tags().

$text= '<p>test paragraph.</p><a href="index.php">Click link</a><p>test paragraph.</p><a href="index.php">Click link</a><p>test paragraph.</p>';

$pos = strpos($text, "<a href"); // find first a href

while($pos !== false){ // loop until there is no more a href
    $pos2 = strpos($text, "</a>", $pos)+4; // find the end tag of the a
    $text = substr($text, 0, $pos) . substr($text, $pos2); // remove the tag and link text
    $pos = strpos($text, "<a href"); // find the next. If none is found "false" is returned meaning while ends.
}

echo strip_tags($text); // strip away other tags.
