How to check if a file doesn't exist in any directory, add into the $notexists array.
foreach($files as $file){
foreach ($folders as $this_folder) {
if (file_exists($this_folder.$file)) {
$exists[] =$file;
continue;
}else{
// What to do if file is not exist in any directory, add into array.
$notexists[] = '';
}
}
You need to wait until the end of the loop to know if the file was not found in any of the directories.
And continue; should be break;. continue restarts starts the next iteration of the current loop, but once you find the file you want to exit the loop completely.
foreach($files as $file){
$found = false;
foreach ($folders as $this_folder) {
if (file_exists($this_folder.$file)) {
$exists[] =$file;
$found = true;
break;
}
}
if (!$found) {
// What to do if file is not exist in any directory, add into array.
$notexists[] = $file;
}
}
you could store them directly after else condition since your using break; you dont have to worry about iteration
foreach($files as $file){
foreach ($folders as $folder_path) {
/* NOTE : the '@' here before the file_exists() function
is to manage this function errors by yourself after the `else` condition ,
otherways you can remove it to see the native php errors .
*/
if (@file_exists($folder_path.$file)) {
$exists[] = $file;
break;
}else{
$notexists[] = $file;
}
}
}
RESULT :
Exist Files :
Array ( [0] => index.php [1] => head.php )
Non Exist ones :Array ( [0] => random_file.random )
but be aware that you need to define those arrays before you use them inside the conditions so you dont get undefined errors later if they return an empty array when you loop them as a result .
so before your first foreach() add those variables definition
$exists = array();
$notexists = array();
$folders = array('./'); // your folders list ofc should be here ..
}else{ after that condition he can sort a custom error spsly if he have a professional script and he want to manage all the errors by himself . but even that you point is good , i should remind him with a note about that , thank you :)You could use array_diff() to check the files that was not found:
foreach($files as $file){
foreach ($folders as $this_folder) {
if (file_exists($this_folder.$file)) {
$exists[] =$file;
break;
}
}
$notexists = array_diff($files, $exists);
$this_folderinfile_exists()?$folder_pathseems to be the same in all iterations of the secondforeach().elseruns if it's not in the current directory, even though it might be in another directory.
