PHP - Image Upload, Fatal Error On Memory Size??

Hi ,

 As you may all have experienced this problem is there way we can non-healthy exit of script ..due to memory problem........???

I got to know..we avoid this......by properly managing our php memory by unset function. remove unusable variables and objects from memory......

Is there any way we can check each time inside the script -to check memory is available  or sleep for some time and check again.......to proceed without exit........

Is there a way to catch this fatal error and take necessary steps to avoid exit........

Thanks,
redfort  :confused:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4864 bytes) in /home/a5418385/public_html/scripts/status.php on line 2 What does this mean?

Hello,

I have no experience when dealing with large files so I am not sure what to do about this. I have attempted to read several large files using file_get_contents ; the task is to clean and munge them using preg_replace().

My code runs fine on small files ; however, the large files (40 MB) trigger an Memory exhausted error:

Code: [Select]
PHP Fatal error:  Allowed memory size of 16777216 bytes exhausted (tried to allocate 41390283 bytes)

I was thinking of using fread() instead but I am not sure that'll work either. Is there a workaround for this problem?

Thanks for your input.

Al.

I'm having real difficulty with something that should simply work... 

I've got a script that reads files within a specific folder defined elsewhere.  Then it returns the filenames (image files) to an array.  Relatively simple, you'd think...

Here's the process loop :

Code: [Select]
// Read directory for images
        @$dh  = opendir($img_dir);
        while (false !== (@$filename = readdir($dh))) {
            if (($filename == '.') || ($filename == '..') || ($filename == 'Thumbs.db')) {
            } else {
            $files[] = $filename;
            }
        }
There is a maximum of 4 images in each folder.  This process will run once per page load.

I have checked my php settings:

memory_limit     256M
post_max_size     64M
upload_max_filesize   62M (just for good measure).

IMHO 256m works for another site I developed which processes up to three images using imagemagick, and I've tested this with a 4mb png file too....

Yet I get this error :

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 35 bytes) in F:\html\bishopstrings\components\com_content\views\article\tmpl\default.php on line 43

This is telling me it's trying to allocate 35bytes when there is 268435456 bytes available... 

Yet this fails - any help 

Hi all

I have a script that takes up to 3 images and resizes them. It works except for if you try and upload images over roughly 500kb. I then get the message:

Fatal error: Allowed memory size of X bytes exhausted (tried to allocate Y bytes)

Here's a snippet of the code for one image:

Code: [Select]
// Process image 1 :

if(!empty($_FILES['image1']['name'])) {
$imagelarge = $_FILES['image1']['tmp_name'];
$imagelargemain = $_FILES['image1']['name'];
$pathInfo = pathinfo($imagelargemain);
$rand = rand(1, 100000000000000);
$name = $rand . '.' . $pathInfo['extension'];
$src = imagecreatefromjpeg($imagelarge);
list($width,$height)=getimagesize($imagelarge);
if ($width > $height) {
$newwidth=600;
$newheight=($height/$width)*$newwidth;
}
elseif ($height > $width) {
$newheight=400;
$newwidth=($width/$height)*$newheight;
}
$center_x = (600/2)-($newwidth/2);
$center_y = (400/2)-($newheight/2);
$tmp=imagecreatetruecolor(600,400);
$white = imagecolorallocate($tmp, 255, 255, 255);
imagefill($tmp, 0, 0, $white);
imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height);
$filename = WEB_UPLOAD."images/adverts/". $name;
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);
$image_sql = mysql_query("UPDATE `adverts` SET image1 ='".$name."' WHERE id='".$insertid."'") or die ("Error updating database");
}

Any ideas why this happens?

Many thanks

Pete

Is there a way I can get the .jpg file in kilobytes from a remote url and check it to make sure it does not exceed 40 kilobytes before it saves the remote url into my database?

Hey there so I'm using the below code to upload images/files to my server via ftp. The issue I've found is that anything bigger than 200KB either stalls out and partially uploads or doesn't upload at all.

I've set my php.ini file to have upload_max_filesize = 1000M and post_max_size = 1000M. And still anything bigger than 200KB won't upload right. Any help would be appreciated. I'm using php version 5.2.14 fyi. Thanks so much.

Hi,

I'm developing a code that uploads images. I need to verify if the image have the minimum size of 100*100 pixels before the upload. How can I do this?

Best Regards,

Sorry for my bad english.

Hi guys, with code below i can upload pictures to database, however i need to limit the file upload. I have this code done with help of php freak forum and i am  a newbie so can u help me please? thanks in advance


if (isset($_POST['register']) && $_POST['register']){
//image1
$nameone=$_FILES['myfileone']['name'];
if ($nameone)

{
$dst_filename = resize_upload_image($_FILES['myfileone'], "images/");
if ($dst_filename !== false) {
extract($dst_filename);
$image1 = mysql_query ("INSERT INTO img SET image='$img_filename', thumb='$thumb_filename', refimage='$reference'");
}
}
}
?>
<form action='' method='POST' enctype='multipart/form-data'>
<p>File:
      <input type='file' name='myfileone'>

(1) What does this actually do? (compress it?)

$image = imagecreatefromjpeg("image.jpg");
header('Content-Type: image/jpeg');
imagejpeg($image);

By using this rather than displaying by using www.site.com/image.jpg it reduces file size of an image from 2.5mb to 0.5mb !!

(2) ImageMagick can't get these results. Am I doing something wrong? If I change the pixel size of an image in ImageMagick then I can reduce its file size, but (1) above reduces file size regardless of changing pixel size.

Hey

My php function keeps returning an error on a valid image! I get this error:

Quote

could not make seekable

I use this line to get the image size but i get the above error for it:$picturearray = getimagesize($Image); 

Url being tested : Code: [Select]
http://www.fileden.com/files/2010/12/22/3043070/Sidroc.jpg
The url is correct and the image does exist - does any one know what can cause this issue ?

Hello guys,

I'm new in php and now I'm trying to make an php installer
Right now it compress php project/dump database with gzip in a file called install.php and the idea is when the user run install.php in his browser he can choose directory, overwrite existing file etc...
The problem is that when I try to run install.php in firefox I get this error: Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 134217728 bytes) in Unknown on line 0
and when I run it with chrome I get this:

Can anyone tell me what might be the problem ? Is it a memory size problem ?

Hello all,   Appreciate if you folks could pls. help me understand (and more importantly resolve) this very weird error:     Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ASC, purchase_later_flag ASC, shopper1_buy_flag AS' at line 3' in /var/www/index.php:67 Stack trace: #0 /var/www/index.php(67): PDO->query('SELECT shoplist...') #1 {main} thrown in /var/www/index.php on line 67   Everything seems to work fine when/if I use the following SQL query (which can also be seen commented out in my code towards the end of this post) :  

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
           FROM shoplist, store_master, item_master
           WHERE     shoplist.store_id = store_master.store_id
                   AND shoplist.item_id = item_master.item_id";

  However, the moment I change my query to the following, which essentially just includes/adds the ORDER BY clause, I receive the error quoted above:

$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name 
		FROM shoplist, store_master, item_master 
		ORDER BY purchased_flag ASC, 
				purchase_later_flag ASC, 
				shopper1_buy_flag ASC, 
				shopper2_buy_flag ASC, 
				store_name ASC) 
		WHERE 	shoplist.store_id = store_master.store_id 
				AND shoplist.item_id = item_master.item_id";

In googling for this error I came across posts that suggested using "ORDER BY FIND_IN_SET()" and "ORDER BY FIELD()"...both of which I tried with no success.   Here's the portion of my code which seems to have a problem, and line # 67 is the 3rd from bottom (third last) statement in the code below:  

                    <?php
                        /*
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
                                FROM shoplist, store_master, item_master
                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        */
                    
                        $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
                                FROM shoplist, store_master, item_master
                                ORDER BY FIND_IN_SET(purchased_flag ASC,
                                                 purchase_later_flag ASC,
                                                 shopper1_buy_flag ASC,
                                                 shopper2_buy_flag ASC,
                                                 store_name ASC)
                                WHERE     shoplist.store_id = store_master.store_id
                                        AND shoplist.item_id = item_master.item_id";
                        $result = $pdo->query($sql);                        
                        
                        // foreach ($pdo->query($sql) as $row) {
                        foreach ($result as $row) {
                            echo '<tr>';
                                print '<td><span class="filler-checkbox"><input type="checkbox" name="IDnumber[]" value="' . $row["idnumber"] . '" /></span></td>';
