# stripos

(PHP 5)

stripos -- Find position of first occurrence of a case-insensitive string

## Description

int stripos ( string haystack, string needle [, int offset] )

Returns the numeric position of the first occurrence of needle in the haystack string. Unlike strpos(), stripos() is case-insensitive.

Note that the needle may be a string of one or more characters.

If needle is not found, stripos() will return boolean `FALSE`.

Varoitus
T�m� funktio voi palauttaa Boolean-arvon `FALSE`, mutta voi my�s palauttaa ei-Boolean-arvon joka evaluoituu arvoksi `FALSE`, kuten 0 tai "". Lis�tietoja Boolean-arvot kappaleesta. K�yt� paluuarvon testaukseen operaattoria ===.

Esimerkki 1. stripos() examples

`<?php
$findme = 'a';
$mystring1 = 'xyz';
$mystring2 = 'ABC';
$pos1 = stripos($mystring1, $findme);
$pos2 = stripos($mystring2, $findme);
// Nope, 'a' is certainly not in 'xyz'
if ($pos1 === false) {
echo "The string '$findme' was not found in the string '$mystring1'";
}
// Note our use of ===. Simply == would not work as expected
// because the position of 'a' is the 0th (first) character.
if ($pos2 !== false) {
echo "We found '$findme' in '$mystring2' at position $pos2";
}
?>`

If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.

The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the the beginning of haystack.
