strstr
Find first occurrence of a string
(PHP 4, PHP 5)
string strstr ( string haystack, string needle, bool before_needle )
Returns part of haystack string from the first occurrence of needle to the end of haystack.
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.
Parameters
- haystack
The input string.
- needle
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
- before_needle
If
TRUE(the default isFALSE), strstr() returns the part of the haystack before the first occurence of the needle.
ChangeLog
