loop through files in directory

[JonnyEnglish]

Hi guys,

I like to run this script for each of the json files in a folder but I’m struggling to get it working and would appreciate some guidance =)

<?php
error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', true);

include_once('db.txt');


///-----------------first effort---------------------------------------------
/// runs without an error but it doesnt produce anything


//$files = glob('C:\php\Inventories\Json.{json}', GLOB_BRACE);
//foreach($files as $file) {


///-----------------second effort---------------------------------------------
/// this produces this interesting error: PHP Warning:  file_get_contents(C:\php\Inventories\Json): failed to open stream: Permission denied in C:\php\Inventories\index.php on line 17 (thats line 27 in this example)



$dir = "C:\php\Inventories\Json";
foreach(glob($dir) as $file)
{

///--------------------------------------------------------------

$json = file_get_contents("$file");

$json = json_decode($json, true);


///--------------------------------------------------------------

$name1 = array();

$name1[] = $json['user_data']['name'];


///------------------- DECK1 ------------------------------------
$deck1 = array();

$id = $json['user_decks']['1']['deck_id'];

$com = $json['user_decks']['1']['commander_id'];
$deck1[] = $commander_id = $d[$com][0];

$dom = $json['user_decks']['1']['dominion_id'];
$deck1[] = $dominion_id = $d[$dom][0];

$card =  $json['user_decks']['1']['cards'];
foreach ($card as $cardid => $cardqty){
$deck1[] = $g = $d[$cardid][0] . "-" . $d[$cardid][1] . "(" . $cardqty . ")";
    
                                        }

///------------------- INVENTORY --------------------------------

$inventory = array();

foreach ($json['user_cards'] as $row => $v){

if ($v['num_owned'] > 0){ 

$inventory[] = $d[$row][0] . "-" . $d[$row][1] . "(" . $v['num_owned'] . ")" . "\n";

                        }
                                            }

sort ($inventory);
$name2 = implode($name1);
$deck2 = implode(",",$deck1);
$inventory2 = implode($inventory);
    

$file = $name2 . ".txt";
file_put_contents($file, $deck2, FILE_APPEND);
file_put_contents($file, $inventory2, FILE_APPEND);

}
?>

"C:\php\Inventories\Json"

 

How many files or directories do you have matching that pattern? Exactly one.

[NigelRel3]

It looks as thought the user that is running the php process (not sure who this is on Windows) doesn't have read access to these files.

Are these files under your webserver root directory (where your PHP scripts are)? (You can rung phpinfo() to check this)  Are the permissions similar to the .php files your running?

[requinix]

The issue is that file_get_contents doesn't work on directories - "Permission denied" is Windows' weird way of telling you that.

 

If you want all files in a directory, and including the paths with the names, then use a simple * wildcard with glob().

glob($dir . "\\*")

And note the escaped backslash since it's a double-quoted string. (Or use forward slashes.) The fact that

"C:\php\Inventories\Json"

worked without them is a coincidence: there are no \p \I \J metacharacters.

Got it, thank you for your help!
