[PHP] Simple File Directory Scanner

[Markshall]

I've been wanting to do one of these for some time as I find them very handy.

Basically, this function I've created allows you to get files from any directory on your webserver.

The code can be found below:

<?php
function GetFiles( $directory, $output_array = false, $exts = array( "png", "jpeg", "jpg", "bmp", "gif" ) )
{
    if ( is_dir( $directory ) )
    {
        $scan  = scandir( $directory );
        $return = array();
        foreach( $scan as $file )
        {
            $ext = strtolower( end( explode( ".", $file ) ) );
            if ( $file !== "." && $file !== ".." & in_array( $ext, $exts ) == true )
            {
                if ( $output_array == true )
                {
                    $return[] = $file;
                }
                else
                {
                    echo $file . "<br />";
                }
            }
        }
        if ( $output_array == true ) return $return;
    }
    else
    {
        echo "Directory {$directory} is invalid!";
    }
}

GetFiles( "images/work" );
?>

The code above will return something similar to this:

<?php
function GetFiles( $directory, $output_array = false, $exts = array( "png", "jpeg", "jpg", "bmp", "gif" ) )
{
    if ( is_dir( $directory ) )
    {
        $scan  = scandir( $directory );
        $return = array();
        foreach( $scan as $file )
        {
            $ext = strtolower( end( explode( ".", $file ) ) );
            if ( $file !== "." && $file !== ".." & in_array( $ext, $exts ) == true )
            {
                if ( $output_array == true )
                {
                    $return[] = $file;
                }
                else
                {
                    echo $file . "<br />";
                }
            }
        }
        if ( $output_array == true ) return $return;
    }
    else
    {
        echo "Directory {$directory} is invalid!";
    }
}

echo "<pre>";
print_r ( GetFiles( "images/work", true ) );
echo "</pre>";
?>

The code above will return something similar to:


You can make the function return an array by adding ", true" after your directory.

Hope this script helps.

Stop using echo. There is a reason we return error codes in PHP. The statement:

if ( $file !== "." && $file !== ".." & in_array( $ext, $exts ) == true ) 

is redundant. If $ext exists in $exts, it will never be "." or ".." Rather than using an O(n) method like in_array(), create an array with file extension keys and boolean values, or something of the sort to force the array to behave as a hash map.

why not use PHP: glob - Manual?
