preg 替换 https 将不起作用

preg replace https won't work

我想删除 http:// & https://

我内联添加:^https?://

preg_replace(array('/(?i)\b((^https?:////\/\/|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}\/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:\'".,<>?«»“”‘’]))/', '/(^|[^a-z0-9_])@([a-z0-9_]+)/i', '/(^|[^a-z0-9_])#(\w+)/u')

尝试失败,语法错误?

如果您只想删除 http://https://(这是您的问题),这将起到作用:

$str = preg_replace('/(https?:\/\/)/', '', 'http://example.com');

如果您只想删除以这些协议之一开头的字符串:

$str = preg_replace('/^(https?:\/\/)/', '', 'http://example.com');

紧跟在初始分隔符之后的^表示"start of the string"。

function remove_http($url) {
 $disallowed = array('http://', 'https://');
 foreach($disallowed as $d) {
   if(strpos($url, $d) === 0) {
      return str_replace($d, '', $url);
   }
 }
 return $url;
}
