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;
    }
?>
