帝国CMS内容字段域名替换函数

帝国CMS给内容字段图片加链接函数，第一个参数是内容，第2个参数是替换域名。

functiondomainReplace($text,$url){$pattern="/<[img|IMG].*?src=['|"](.*?(?:[.jpg|.jpeg|.png|.gif|.bmp]))['|"].*?[/]?>/";$text=stripSlashes($text);returnpreg_replace_callback($pattern,function($matches)use($url){if('/'!==substr($matches[1],0,1)&&'http'!==substr($matches[1],0,4)){returnstr_replace($matches[1],$url.$matches[1],$matches[0]);}return$matches[0];},$text);}

升级版

functiondomainReplace($content='',$url='',$s=0){$pattern="/<[img|IMG].*?src=['|"](.*?(?:[.gif|.jpg|.png]))["|'].*?[/]?>/";returnpreg_replace_callback($pattern,function($matches)use($url){if(1===$s&&false!==stristr($matches[0],$url)){returnstr_replace($url,'',$matches[0]);}elseif(0===$s&&'/'!==substr($matches[1],0,1)&&'http'!==substr($matches[1],0,4)){returnstr_replace($matches[1],$url.$matches[1],$matches[0]);}else{return$matches[0];}},$content);}
