Description
string
strstr ( string haystack, string needle )
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.
注:
This function is case-sensitive. For case-insensitive searches, use
stristr().

注:
If you only want to determine if a particular needle
occurs within haystack, use the faster and less memory
intensive function strpos() instead.
strstr() has been binary safe since PHP 4.3.0
