警告:preg_match() [function.preg-match]:分隔符不能是字母数字或反斜杠

Warning: preg_match() [function.preg-match]: Delimiter must not be alphanumeric or backslash

推荐答案

您的模式需要一个分隔符.它应该像这样添加在模式的开头和结尾:

You need a delimiter for your pattern. It should be added at the start and end of the pattern like so:

$pattern = "/My name is '(.*)' and im fine/";  // With / as a delimeter
