Why will my upload form not upload files over 2.1mb using php?

Question

I am using an upload script that is working great:

ini_set('memory_limit', '256M');
function uploadImage($files_name, $files_tmp_name, $files_error, $files_type, $uploaded_photos_array, $image_type, $replace_position='69') { //Checks if the file uploaded correctly, saves the folder name to the DB, and calls the resizeAndPlaceFile 3 times 
 global $address;
 //If the directory doesn't exist, create it
 if (!is_dir('../images/uploads/temp/'.$address)) {
 mkdir('../images/uploads/temp/'.$address);
 }
 $myFile_original = $files_name; //Store the filename into a variable
 //Change the filename so it is unique and doesn't contain any spaces and is all lowercase
 $myFile = str_replace(' ', '_', $myFile_original); //change all spaces to underscores within a file name
 $myFile = strtolower($myFile); //Make all characters lowercase
 //$anyNum = rand(20,500789000); //Generate a random number between 20 and 500789000 
 //$newFileName = $anyNum.'_'.$myFile; //Combine the random number with the filename to create a unique filename
 $newFileName = $myFile;
 $info = pathinfo($newFileName); //Finds the extension of the filename
 $directory_name = basename($newFileName,'.'.$info['extension']); //Removes the extension from the filename to use as the name of the directory
 $folder = '../images/uploads/temp/'.$address.'/'.$directory_name.'/'; //Folder to upload to
 //If the directory doesn't exist, create it
 if (!is_dir($folder)) {
 mkdir($folder);
 }
 //===Check if the File already exists======== 
 if (file_exists($folder.'large.jpg')) {
 echo $myFile_original." already exists.";
 } //******If file already exists in your Folder, It will return zero and Will not take any action===
 else { //======Otherwise File will be stored in your given directory and Will store its name in Database===
 //copy($_FILES['fileField']['tmp_name'],$folder.$newFileName); //===Copy File Into your given Directory,copy(Source,Destination)
 // Check if file was uploaded ok
 if(!is_uploaded_file($files_tmp_name) || $files_error !== UPLOAD_ERR_OK) {
 exit('There was a problem uploading the file. Please try again.');
 } else {

When I try to upload any file above 2.1mb, it won't upload the file and won't display any error so I have no idea why it is not working. Why will my upload form not upload files over 2.1mb using php?

Answer 1

Check and change the following php.ini instructions:

memory_limit = 32M
upload_max_filesize = 10M
post_max_size = 20M

Answer 2

update these parameters in your php.ini

upload_max_filesize
post_max_size

Answer 3

You can't change maximum file upload size from your php script. You should change in php.ini file as upload_max_filesize = 30M post_max_size = 30M

Some hosters dosen't allow to change php.ini(in case of shared hosting) in that u should use .htaccess and use following php_value upload_max_filesize 30M
