i have this code for file update and i need to put the files path in response array. but my array is empty:
$response = array();
if (file_exists($directorSerie)) {
if(is_array($_FILES)) {
foreach ($_FILES['fileToUpload']['name'] as $name => $value){
if(is_uploaded_file($_FILES['fileToUpload']['tmp_name'][$name])) {
$sourcePath = $_FILES['fileToUpload']['tmp_name'][$name];
$targetPath = $directorSerieString.$_FILES['fileToUpload']['name'][$name];
array_push($response, $targetPath);
if(move_uploaded_file($sourcePath,$targetPath)) {
$success = "success";
}
}
}
}
}
exit(json_encode($response));
array_push() works on foreach.
I sugest you to put dubug to found where is the mistakes.
You could put var_dump($var) after level of your code, like this:
if (file_exists($directorSerie)) {
var_dump($directorSerie);
Next...
if(is_array($_FILES)) {
var_dump($_FILES)
Next
foreach ($_FILES['fileToUpload']['name'] as $name => $value){
var_dump( $name ,$value);
up until you discover...

What causes this warning?
You should check that what you are passing to foreach is an array by using the is_array function
If you are not sure it's going to be an array you can always check using the following PHP example code:
if (is_array($variable)) {
foreach ($variable as $item) {
//do something
}
}
This means that you are doing a foreach on something that is not an array.
Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.
Then fix the one where it isn't an array.
How to reproduce this error:
<?php
$skipper = "abcd";
foreach ($skipper as $item){ //the warning happens on this line.
print "ok";
}
?>
Make sure $skipper is an array.
Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach that is not an array.
Look at what you're passing into foreach, determine what it is (with var_export), find out why it's not an array... and fix it.
Basic, basic debugging.
Try this.
if(is_array($value) || is_object($value)){
foreach($value as $item){
//somecode
}
}
I have a script which takes a zipped CSV file, unzips it, and removes duplicate entries. It was mostly working, until I moved the unzip code into a function. Now it fails to unzip the .zip file, but doesn't show an error.
Checked file/folder permissions, everything is 777 on dev machine.
<?php
//
//huge memory limit for large files
$old = ini_set('memory_limit', '8192M');
//
//create a string like the filename
$base_filename = 'csv-zip-file'.date('m').'_'.date('d').'_'.date('Y');
//
//if the file exists ...
//unzip it
//read it to an array
//remove duplicates
//save it as a new csv
if (file_exists($base_filename.'.zip')) {
$zip_filename = $base_filename.'.zip';
echo "The file <strong>$zip_filename</strong> exists<br>";
unzip($zip_filename);
$csv = csv_to_array();
$csv = unique_multidim_array($csv,"Project Id");
var_dump($csv);
} else {
echo "The file <strong>$base_filename.zip</strong> does not exist";
}
function unzip($file_to_unzip) {
$zip=new ZipArchive();
if($zip->open($file_to_unzip)==TRUE) {
$address=__DIR__;
$zip->extractTo($address);
$res=$zip->close();
echo 'ok';
}
else{
echo 'failed';
}
}
function unique_multidim_array($array, $key) {
$temp_array = array();
$i = 0;
$key_array = array();
foreach($array as $val) {
if (!in_array($val[$key], $key_array)) {
$key_array[$i] = $val[$key];
$temp_array[$i] = $val;
}
$i++;
}
return $temp_array;
}
function csv_to_array () {
// global $filename;
global $base_filename;
$rows = array_map('str_getcsv', file($base_filename.'.csv'));
//using array_pop to remove the copyright on final row
array_pop($rows);
$header = array_shift($rows);
$csv = array();
foreach ($rows as $row) {
$csv[] = array_combine($header, $row);
}
return $csv;
}
Interesting problem you have here.
Output $file_to_unzip right inside the function.
Does $zip->* have an last_error or last_response method? See
what the ZipArchive class IS returning.
Do you have access to the php error logs? Let's look there for any output.
I am trying to move all the files in my array from one directory to another.
I have done some research and are using the php Copy() function.
here is my code so far:
$filenameArray = "img1.png,img2.png,img3.png";
$sourcePath = "/source/";
$savePath = "/newDir/";
$myArray = explode(',', $filenameArray);
$finalArray = print_r($myArray);
function copyFiles($finalArray,$sourcePath,$savePath) {
for($i = 0;$i < count($finalArray);$i++){
copy($sourcePath.$finalArray[$i],$savePath.$finalArray[$i]);}
}
Anyone see where I'm going wrong?
Thanks in advance!
This is the unlink ive been attempting to use.
function copyFiles($finalArray,$sourcePath,$savePath) {
foreach ($finalArray as $file){
if (!copy($sourcePath.$file,$savePath.$file)) {
echo "Failed to move image";
}
$delete[] = $sourcePath.$file;
}
}
// Delete all successfully-copied files
foreach ( $delete as $file ) {
unlink( $sourcePath.$file );
}
My Final Working Code
the code below moves images in comma seperated array to new folder and removes them from current folder
$finalArray = explode(',', $filenameArray);
function copyFiles($finalArray,$sourcePath,$savePath) {
foreach ($finalArray as $file){
if (!copy($sourcePath.$file,$savePath.$file)) {
echo "Failed to move image";
}
}
}
copyFiles( $finalArray, $sourcePath, $savePath);
function removeFiles($finalArray,$sourcePath) {
foreach ($finalArray as $file){
if (!unlink($sourcePath.$file)) {
echo "Failed to remove image";
}
}
}
removeFiles( $finalArray, $sourcePath);
In your code you are not calling the copyFile function. Try this:
$filenameArray = "img1.png,img2.png,img3.png";
$sourcePath = "/source/";
$savePath = "/newDir/";
$finalArray = explode(',', $filenameArray);
function mvFiles($finalArray,$sourcePath,$savePath) {
foreach ($finalArray as $file){
if (!rename($sourcePath.$file,$savePath.$file)) {
echo "failed to copy $file...\n";
}
}
}
mvFiles( $finalArray, $sourcePath, $savePath);
A simple solution :
$filenameArray = "img1.png,img2.png,img3.png";
$sourcePath = "/source/";
$savePath = "/newDir/";
$myArray = explode(',', $filenameArray);
$finalArray = $myArray; //corrected this line
function copyFiles($finalArray, $sourcePath, $savePath)
{
for ($i = 0; $i < count($finalArray); $i++)
{
copy($sourcePath.$finalArray[$i],$savePath.$finalArray[$i]);
}
}
Hope you have right call to function copyFiles().
UPDATE for unlink() :
Let me try to throw some light on your work (written code):
foreach ($finalArray as $file)
{
if (!copy($sourcePath.$file,$savePath.$file))
{
echo "Failed to move image";
}
$delete[] = $sourcePath.$file;
}
Contents of $delete :
a. /source/img1.png
b. /source/img2.png
c. /source/img3.png
Now,
foreach ( $delete as $file )
{
unlink( $sourcePath.$file );
}
unlink() will be called with the following parameters:
$sourcePath.$file : /source/./source/img1.png : /source//source/img1.png => No such path exists
$sourcePath.$file : /source/./source/img2.png : /source//source/img2.png => No such path exists
$sourcePath.$file : /source/./source/img3.png : /source//source/img3.png => No such path exists
$sourcePath.$file : /source/./source/img4.png : /source//source/img4.png => No such path exists
I think for this reason, unlink is not working.
The code to be written should be like the following:
foreach ( $delete as $file )
{
unlink( $file );
}
Now, unlink() will be called with the following parameters:
a. /source/img1.png => path do exists
b. /source/img2.png => path do exists
c. /source/img3.png => path do exists
Do tell me if this does not solves the issue.
Update as per Dave Lynch's code:
$filenameArray = "img1.png,img2.png,img3.png";
$sourcePath = "/source/";
$savePath = "/newDir/";
$finalArray = explode(',', $filenameArray);
foreach ($finalArray as $file)
{
$delete[] = $sourcePath.$file;
}
foreach ( $delete as $file )
{
echo $sourcePath.$file . "</br>";
}
Output:
/source//source/img1.png
/source//source/img2.png
/source//source/img3.png
Please check.
Thanks and Regards,

how can output of inside foreach with serialize store in database? next: called of database?
please give me example.
foreach($upload_data as $file) {
echo serialize($file['file']);
}
output: s:54:"Chrysanthemum6.jpg";s:47:"/Desert6.jpg";
With respect
Something like this?
$result = array();
foreach ($upload_data as $file) {
$result[] = $file['file'];
}
var_dump(serialize($result));
store the serialize in a variable?
$result = '';
foreach($upload_data as $file) {
$result .= serialize($file['file'];
}
echo $result;
