mb_strripos

(PHP 5 >= 5.2.0)

mb_strripos — Finds position of last occurrence of a string within another, case insensitive

Descripción

int mb_strripos ( string $haystack , string $needle [, int $offset = 0 [, string $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.

Parámetros

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
encoding: Character encoding name to use. If it is omitted, internal character encoding is used.

Valores devueltos

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;


    }


?>
