strstr — Find first occurrence of a string

Note: This function is case-sensitive. For case-insensitive searches, use stristr().
Note: If you only want to determine if a particular needle occurs within haystack , use the faster and less memory intensive function strpos() instead.
The input string.
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
If TRUE (the default is FALSE), strstr() returns the part of the haystack before the first occurence of the needle .
