正则表达式

[img]XXXXXXg;base64,iVQA/XXXXXXXXXXXXXXX[/img]

如何把[img] 与[/img]之间的内容替换成空?

回复讨论(解决方案)

$s = '[img]XXXXXXg;base64,iVQA/XXXXXXXXXXXXXXX[/img]';echo preg_replace('/(?[img][/img]  
  
   
$s = '[img]XXXXXXg;base64,iVQA/XXXXXXXXXXXXXXX[/img]';echo preg_replace('/(?[img][/img]    
$s = '[a]XXXXXXg;base64,iVQA/XXXXXXXXXXXXXXX[/a]';echo preg_replace('/(?[a][/a]  
 a标签或其它标签包含的内容也被替换了,怎么把它写死,仅针对[img][/img]  
  
echo preg_replace('/(?  
  
$str = '[img]XXXXX[/img]';$regx = '/\[img\](.*)\[\/img\]/';$rep_result = preg_replace_callback(	$regx, 	function($match){		return str_replace($match[1],'',$match[0]);	},	$str);
