robcrozier Posted March 8, 2007 Share Posted March 8, 2007 Hi, can anyone tell me how i can check to see if a large string contains a substring in any position at all, by this i mean that the substring could occur at the start, middle or end of the actual string. If the substring is found i would then like a flag to be raised. maybe using a boolean or something. thanks guys!

skali Posted March 8, 2007 Share Posted March 8, 2007 int strpos ( string haystack, mixed needle [, int offset] ) Returns the numeric position of the first occurrence of needle in the haystack string. Unlike the strrpos(), this function can take a full string as the needle parameter and the entire string will be used. www.php.net/function.strpos Link to comment https://forums.phpfreaks.com/topic/41798-how-to-tell-if-a-string-contains-a-substring/#findComment-202708 Share on other sites More sharing options...
