PHP: filename without file extension- best way?

Question

I am trying to pull the filename out of a directory without the extension.

I am kludging my way through with the following:

foreach ($allowed_files a         


        

Answer 1

try this

function file_extension($filename){
    $x = explode('.', $filename);
    $ext=end($x);
    $filenameSansExt=str_replace('.'.$ext,"",$filename);
    return array(
        "filename"=>$filenameSansExt,
        "extension"=>'.'.$ext,
        "extension_undotted"=>$ext
        );
}

usage:

$filenames=array("file1.php","file2.inc.php","file3..qwe.e-rt.jpg");
foreach($filenames as $filename){
    print_r(file_extension($filename));
    echo "\n------\n";

}

output

Array
(
    [filename] => file1
    [extension] => .php
    [extension_undotted] => php
)

------
Array
(
    [filename] => file2.inc
    [extension] => .php
    [extension_undotted] => php
)

------
Array
(
    [filename] => file3..qwe.e-rt
    [extension] => .jpg
    [extension_undotted] => jpg
)
