Get name and ext from filename?

[ziah75]

Hi!

This should be pretty simple, but has kept me surfing these posts forever...

I have a filename variable which I want to split in 2 parts.

Example (which is a tricky filename, since it has 2 dots):

$filename = "somefile.name.jpg"

The first part should be: somefile.name
The second: jpg

If it was just one . there wouldn't be any problem, explode would solve that easily. But I can't rely on people uploading files with "good" filenames ;-).

So how do i split a string in two parts, at the location of the last . ?

Maybe there's some regexp that can solve this?

Any suggestions are very much appreciated.

little something I cooked up on my desk, if there is a faster way I am always open to hear it.

function ext_file($file) {
return substr($file,-3);
}

function file_name($file) {
return substr($file,0,strlen($file) - 4);
}

you're looking for the strrpos() function. it searches a string from right to left for the first occurrence of a character. i wrote a quick example for you. the following code separates the filename passed to it into a left filename and a right extension.

<?php

function printStrippedWord($testVar){

$beginExtLocation = (strrpos ($testVar, '.') + 1);
$extLength = strlen($testVar) - strrpos($testVar, '.');

$nameLength = strlen($testVar) - $extLength;


$extension = substr($testVar, $beginExtLocation, $extLength);

$fileName = substr($testVar, 0, $nameLength); 


echo "Filename:<br>";
echo $fileName;

echo "<p>Extension:<br>";
echo $extension;

}

printStrippedWOrd('one.two.THREE.four');
?>

Here's an easy way:

$ext= strrchr ($file, ".");
$prefile = eregi_replace($ext, "", $file);
