How to get file extension using PHP by Anil Kumar Panigrahi
See the following script :
Type 1:
<?php
function findextension ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
$filename="image.jpg";
echo findextension ($filename);
// Here we will get the file extension
$filename="image.jpg";
echo findextension ($filename);
// Here we will get the file extenstion
?>
function findextension ($filename)
{
$filename = strtolower($filename) ;
$exts = split("[/\\.]", $filename) ;
$n = count($exts)-1;
$exts = $exts[$n];
return $exts;
}
$filename="image.jpg";
echo findextension ($filename);
// Here we will get the file extension
$filename="image.jpg";

Another way to get file extension:
<?php
function file_extension($filename)
{
return end(explode(".", $filename));
}
echo file_extension("anil.labs.jpg");
?>
function file_extension($filename)
{
return end(explode(".", $filename));
}
echo file_extension("anil.labs.jpg");
?>
