Returns part of haystack string starting from and including the
first
occurrence of needle to the end of
haystack.
This function is case-sensitive. For case-insensitive searches, use stristr().
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, strstr()
returns
the part of the haystack before the first
occurrence of the needle (excluding the needle).
Returns the portion of string, or FALSE if needle
is not found.
