Every installation of PHP has a default or global php.ini file for the default PHP settings. Normally it is suggested to leave the default or global php.ini file unaltered and to simply create your own php.ini file wherever needed to override the default settings. You can create the php.ini file using a text editor and saving the file to the folder where the settings should apply. Please note that using a php.ini file to override the default settings will only alter the PHP settings for all PHP files in the directory where it is saved. This means that any PHP files in subfolders will not recognize the changes you've made in the php.ini file. You will have to copy the file to any subdirectories needed.
Write each directive along with its value on separate lines. Lines starting with a hash symbol (#) are comment lines and have no effect on the settings within the file.
An example:
; at least 64M
memory_limit = 64M;
upload_max_filesize = 10M;
post_max_size = 12M;
Make sure that post_max_size is larger than the upload_max_size.
