Recursive File Search (PHP)

Viewed 47359

I'm trying to return the files in a specified directory using a recursive search. I successfully achieved this, however I want to add a few lines of code that will allow me to specify certain extensions that I want to be returned.

For example return only .jpg files in the directory.

Here's my code,

<?php
$it = new RecursiveDirectoryIterator("L:\folder\folder\folder");
foreach(new RecursiveIteratorIterator($it) as $file) {
echo $file . "<br/> \n";
}
?>

please let me know what I can add to the above code to achieve this, thanks

None of these worked for my case. So i wrote this function, not sure about efficiency, I just wanted to remove some duplicate photos quickly. Hope it helps someone else.

function rglob($dir, $pattern, $matches=array())
{
    $dir_list = glob($dir . '*/');
    $pattern_match = glob($dir . $pattern);

    $matches = array_merge($matches, $pattern_match);

    foreach($dir_list as $directory)
    {
        $matches = rglob($directory, $pattern, $matches);
    }

    return $matches;
}

$matches = rglob("C:/Bridge/", '*(2).ARW');

Only slight improvement that could be made is that currently for it to work you have to have a trailing forward slash on the start directory.

In this sample code;

  • You can set any path for $directory variable, for example ./, 'L:\folder\folder\folder' or anythings...
  • And also you can set a pattern file name in $pattern optional, You can put '/\.jpg$/' for every file with .jpg extension, and also if you want to find all files, can just use '//' for this variable.
$directory = 'L:\folder\folder\folder';
$pattern = '/\.jpg$/'; //use "//" for all files
$directoryIterator = new RecursiveDirectoryIterator($directory);
$iteratorIterator = new RecursiveIteratorIterator($directoryIterator);
$regexIterator = new RegexIterator($iteratorIterator, $pattern);
foreach ($regexIterator as $file) {
    if (is_dir($file)) continue;
    echo "$file\n";
}

here is the correct way to search in folders and sub folders

$it = new RecursiveDirectoryIterator(__DIR__);
$findExts = Array ( 'jpeg', 'jpg' );
foreach(new RecursiveIteratorIterator($it) as $file)
{        
    $ext = pathinfo($file, PATHINFO_EXTENSION);
    if(in_array($ext, $findExts)){
        echo $file.PHP_EOL;
    }
}
