Upload and Resize Large image using PHP

Hello experts,

I am new to PHP and I am developing Image Gallery component. Everything is working fine.

I can upload image upto 2MB and get resize it but cannot upload and resize larger image.

I tried to update settings in php.ini file and its working fine but on client's end php.ini is not accessible. Also, I tried to update via .htaccess but it gives me "Internal Error" on client's end.

My server is IIS and Client's Server is Linux based Apache.

Thanks in Advance.

Below is My Code:

Hi, use this link

http://www.thewebhelp.com/php/scripts/image-upload-with-resize/

d4011

      ini_set('upload_max_filesize', '8388608');
      ini_set('post_max_size', '8388608');

Open in new window

That will not work. As stated here:
http://www.php.net/manual/en/ini.core.php
upload_max_filesize and post_max_size are only PHP_INI_PERDIR changeable. So you have to make these settings in a .htaccess file.
Is PHP running in "CGI mode" or as Apache module? If PHP is running in "CGI mode" you can't make these settings via .htaccess. You have to adjust them in php.ini.

Beverley Portlock

The 2MB limit sounds familiar. PHP has a number of limits built in to it and one of these is file upload size. It is usually set to 2MB but you can change it by editing PHP.INI and finding

upload_max_filesize = 2M

and change 2M to 4M or whatever you like. Also read this http://php.net/manual/en/ini.core.php and scan for "File Uploads"

Monis Monther

I just want to add a simple notet to what has been posted above.

If your client has php installed as a CGI instead of an apache module. For example he has suPHP installed then you cannot put the above changes in a .htaccess file. You should put them directly under php.ini of it you dont have access to it then you create a php.ini file in your clients /home and put those values in it.

The syntax is different between .htaccess file and php.ini
For php.ini follow the syntax posted by bportlock

Hi small_student,

I think php is installed as CGI. But can you please verify ?

On runnint phpinfo(); I get "Server API -> CGI/FastCGI ". Does it means CGI ? if you want phpinfo() url i am ready to give.

Hi,
Will it be ok as php.ini ? And, will it effect other php.ini settings ?

[PHP]
post_max_size = 12M
upload_max_filesize = 12M
max_execution_time = 1200
max_input_time = 1200
memory_limit = -1

Monis Monther

Now I would not advise of putting memory limit to unlimited, this would make you open for memory leaks and memory DOS attacks. At least put some limit for memory

dotsandcoms

ASKER

ok..sure...i'll put 128M there as php.ini default...

but my question is do i have to put only this in php.ini or need to make whole php.ini ?

Beverley Portlock

You can either use a directory vbased php.ini or the global one. I would stick it in the global one as it keeps it away from sticky fingers that might want to fiddle or people deleting what they think is "duff" files when tidying up. If you pout it in the global version then it is out of the way and safe and none of your limits are outrageous or silly as long as you set the memory limit to 128M

Hi small_student,
I put php.ini in root directory of site but doesn't solve the problem. Do i have to tell server techsupport to allow.

Monis Monther

I am not really sure, You can ask them of how to achieve this.
