如何從字符串中刪除第一個鏈接？

Question

如何使用PHP從本文中刪除與圖像的第一個鏈接？

<a href="some link"><img src="image link" /></a>Lorem ipsum dolor sit amet, consectetur adipiscing elit.** 

Answer 1

我將通過分割由 '>' 字符行開始..

PHP：

$line = "<a href=''><img src=''></a>blah blah blah"; 
$parts = explode('>', $line); 

如果您想要的圖像....

$img = $parts[1].">"; 

如果你只想要文字...

$text = $parts[3]; 

Answer 2

$str = '<a href="some link"><img src="image link"></a>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<a href="some link"><img src="image link"></a>'; 

// strip the entire <a> tag including contents (first occurrence only) 
$str = preg_replace('/<a.*?<\/a>/', '', $str, 1); 

// strip only the <a> leaving the inner HTML (first occurrence only) 
$str = preg_replace('/<a[^>]*>(.*?)<\/a>/', '$1', $str, 1); 

Answer 3

$doc = DOMDocument::loadHTML($html); 
$link = $doc->getElementsByTagName('a')->item(0); 
$link->parentNode->removeChild($link); 
$html = $doc->saveHTML();
