(PHP 5 >= 5.2.0, PHP 7)
mb_strripos — Finds position of last occurrence of a string within another, case insensitive
$haystack
, string $needle
[, int $offset = 0
[, string $encoding = mb_internal_encoding()
]] )
mb_strripos() performs multi-byte safe
strripos() operation based on
number of characters. needle position is
counted from the beginning of
haystack. First character's position is
0. Second character position is 1.
Unlike mb_strrpos(),
mb_strripos() is case-insensitive.
haystack
The string from which to get the position of the last occurrence
of needle
needle
The string to find in haystack
offset
The position in haystack
to start searching
encodingCharacter encoding name to use. If it is omitted, internal character encoding is used.
Return the numeric position of
the last occurrence of needle in the
haystack string, or FALSE
if needle is not found.
Here are Java like startsWith/endsWith implementations in PHP.
<?php
function startsWith($haystack,$needle)
{
$res=FALSE;
if(mb_strripos($haystack,$needle,0,"utf-8")==0)
$res= TRUE;
return $res;
}
function endsWith($haystack,$needle)
{
$res=FALSE;
$len=mb_strlen($haystack);
$pos=$len-mb_strlen($needle);
if(mb_strripos($haystack,$needle,0,"utf-8")==$pos)
$res= TRUE;
return $res;
}
?>
