php - 分隔符不能是字母数字或反斜杠和 preg_match

Question

我有这个代码:

$string1 = "My name is 'Kate' and im fine"; 
$pattern = "My name is '(.*)' and im fine"; 
preg_match($pattern , $string1, $matches);
echo $matches[1];

当我运行它返回这个错误:

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

Answer 1

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:

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