Find all .php files in folder recursively - php

Question

Using PHP, how can I find all .php files in a folder or its subfolders (of any depth)?

Answer 1

You can use RecursiveDirectoryIterator and RecursiveIteratorIterator:
$di = new RecursiveDirectoryIterator(__DIR__,RecursiveDirectoryIterator::SKIP_DOTS);
$it = new RecursiveIteratorIterator($di);
foreach($it as $file) {
if (pathinfo($file, PATHINFO_EXTENSION) == "php") {
echo $file, PHP_EOL;
}
}

Answer 2

just add something like:
function listFolderFiles($dir){
$ffs = scandir($dir);
$i = 0;
$list = array();
foreach ( $ffs as $ff ){
if ( $ff != '.' && $ff != '..' ){
if ( strlen($ff)>=5 ) {
if ( substr($ff, -4) == '.php' ) {
$list[] = $ff;
//echo dirname($ff) . $ff . "<br/>";
echo $dir.'/'.$ff.'<br/>';
}
}
if( is_dir($dir.'/'.$ff) )
listFolderFiles($dir.'/'.$ff);
}
}
return $list;
}
$files = array();
$files = listFolderFiles(dirname(__FILE__));

Answer 3

I modified the code a bit created by supajason
Because the code provided did not return a consistent result:
Mainly due to the nomenclature used.
I also added some functionality.
<?php
define('ROOT', str_replace('\\', '/', getcwd()).'/');
///########-------------------------------------------------------------
///########-------------------------------------------------------------
///######## FUNCTION TO LIST ALL FILES AND FOLDERS WITHIN A CERTAIN PATH
///########-------------------------------------------------------------
///########-------------------------------------------------------------
function list_folderfiles(
$dir, // *** TARGET DIRECTORY TO SCAN
$return_flat = true, // *** DEFAULT FLAT ARRAY TO BE RETURNED
$iteration = 0 // *** INTERNAL PARAM TO COUNT THE FUNCTIONS OWN ITERATIONS
){
///######## PREPARE ALL VARIABLES
$dir = rtrim($dir, '/'); // *** REMOVE TRAILING SLASH (* just for being pretty *)
$files_folders = scandir($dir); // *** SCAN FOR ALL FILES AND FOLDERS
$nested_folders = []; // *** THE NESTED FOLDERS BUILD ARRAY
static $total_files = []; // *** THE TOTAL FILES ARRAY
///######## MAKE SURE THAT THE STATIC $fileS ARE WILL BE CLEARED AFTER THE FIRST ITERATION, RESET AS EMPTY ARRAY
if($iteration === 0) $total_$files = [];
///######## RUN THROUGH ALL $fileS AND FOLDERS
foreach($files_folders as $file){
///######### IF THE CURRENT ``file`` IS A DIRECTORY UP
if($file === '.' || $file === '..') continue;
///######### IF IT CONCERNS A $file
if(is_dir($dir.'/'.$file)){
$iteration++; // *** RAISE THE ITERATION
$nested_folders[] = list_folderfiles($dir.'/'.$file, false, $iteration); // *** EXECUTE THE FUNCTION ITSELF
}
///######### IF IT CONCERNS A $file
else{
$total_files[] = $dir.'/'.$file; // *** ADD THE $file TO THE TOTAL $fileS ARRAY
$nested_folders[] = $file; // *** ADD THE $file TO THE NESTED FOLDERS ARRAY
}
}
///########==================================================
///######## IF A FLAT LIST SHOULD BE RETURNED
///########==================================================
if($return_flat) return $total_files;
///######## IF A NESTED LIST SHOULD BE RETURNED
else return $nested_folders;
///########==================================================
}
$files = list_folderfiles(ROOT, true); // *** FLAT ARRAY
///$files = list_folderfiles(ROOT, false); // *** NESTED ARRAY
echo print_r($files, true);

Answer 4

This is similar to another answer here, but removes SKIP_DOTS as it's not needed, and and works with strict_types:
<?php
$o_dir = new RecursiveDirectoryIterator('.');
$o_iter = new RecursiveIteratorIterator($o_dir);
foreach ($o_iter as $o_info) {
if ($o_info->getExtension() == 'php') {
echo $o_info->getPathname(), "\n";
}
}
