strstr:Returns part of haystack string from the first occurrence of needle to the end of haystack.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. This function is case-sensitive. For case-insensitive searches, use stristr().

strstr() returns part of a given string from the first occurrence of a given substring to the end of the string.
For example: strstr(“user@example.com”,”@”) will return “@example.com”.stristr() is idential to strstr() except that it is case insensitive.
