Descrição

int mb_strripos ( string $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.

Parâmetros

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.

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;
    }
?>
