strpos

Description

string strpos(string haystack, string needle);

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.

If needle is not found, returns false.

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

See also strrpos(), strrchr(), substr(), and strstr().
