What is php.ini<\/span>?<\/h3>\n

php.ini<\/span> is a file that allows you to control your PHP settings on your server. When your PHP starts, it will consult your <\/span>php.ini<\/span> files to see how PHP settings should be configured. So, naturally, if you make changes to the <\/span>php.ini<\/span> file, you may have to restart your PHP processes to see those changes go into effect.<\/span><\/p>\n

The php.ini<\/span> file can be used in many ways, some of which include:<\/span><\/p>\n\n\n\n\n\n
upload_max_filesize<\/b><\/td>\nLimiting the maximum file size that can be uploaded<\/span><\/td>\n<\/tr>\n
max_file_uploads<\/b><\/td>\nLimiting the maximum number of files that can be uploaded at the same time<\/span><\/td>\n<\/tr>\n
max_execution_time<\/b><\/td>\nLimiting the maximum time a script can run before it\u2019s terminate<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

php.ini<\/span> uses commands called \u201cdirectives\u201d to communicate with the server. You can find a <\/span>list of <\/span>php.ini<\/span> directives<\/span><\/a> on the PHP documentation site. Make sure you check the \u201cmodes\u201d of the directives so you know they are compatible with the <\/span>php.ini<\/span> file. \u00a0Modes are really just categories that help you figure out which directives can be used in certain PHP files. If you refer to the PHP documentation site\u2019s list of <\/span>php.ini<\/span> directives, you will see that each directive has a mode associated with it. These modes are listed in the <\/span>Changeable <\/b>column.<\/span><\/p>\n

Optionally, you can also group <\/span>php.ini<\/span> directives together into \u201csections.\u201d While this does not immediately affect your PHP, it can be used to group directives together and apply them to specific hosts or paths. Check out the<\/span> list of <\/span>php.ini<\/span> sections<\/span><\/a> on the PHP documentation site. \u00a0<\/span><\/p>\n

The <\/span>php.ini<\/span> file has a blanket effect. How it\u2019s configured will dictate how all your server directories are configured. However, if you want to make an exception for a directory, you would use a <\/span>.user.ini <\/span>file.<\/span><\/p>\n

What is .user.ini<\/span>?<\/h3>\n

.user.ini<\/span> file controls the PHP settings of a single directory. It will only affect the directory it is in. However, each directory may have a <\/span>user.ini<\/span> file.<\/span><\/p>\n

There are only certain directives allowed for use in a<\/span> .user.ini<\/span> file. The allowed directories belong to the <\/span>php_ini_perdir <\/span>and <\/span>php_ini_user<\/span> modes. Be sure to check the <\/span>Changeable<\/b> column of the<\/span> php.ini<\/span> directives list <\/span><\/a>to see if the directive is usable with the <\/span>.user.ini <\/span>file.<\/span><\/p>\n

One directive to keep in mind is the <\/span>user_ini.filename_ttl<\/span>. This directive establishes how often the <\/span>.user.ini<\/span> file is checked for changes. Depending on what frequency this directive is set to, changes to PHP may experience a slight delay before being implemented. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
