You may edit your PHP configuration in Basic Mode or in Advanced Mode.

Directive Info Value
asp_tags Enables the use of ASP-like <% %> tags in addition to the usual tags. This includes the variable-value printing shorthand of <%= $value %>.
enable_dl This directive is really only useful in the Apache module version of PHP. You can turn dynamic loading of PHP extensions with dl() on and off per virtual server or per directory. The main reason for turning dynamic loading off is security. With dynamic loading, it is possible to ignore all open_basedir restrictions. The default is to allow dynamic loading, except when using safe mode. This feature is deprecated, and will be removed at a future time.
file_uploads Whether or not to allow HTTP file uploads.
include_path Specifies a list of directories where the require(), include(), fopen(), file(), readfile() and file_get_contents() functions look for files. The format is like the system's PATH environment variable: a list of directories separated with a colon in Unix or semicolon in Windows.
max_execution_time This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. This helps prevent poorly written scripts from tying up the server. The default setting is 30.
max_input_time This sets the maximum time in seconds a script is allowed to parse input data, like POST, GET and file uploads.
max_input_vars This sets the maximum number of input variables allowed per request and can be used to deter denial of service attacks involving hash collisions on the input variable names.
memory_limit This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server. Note that to have no memory limit, set this directive to -1.
session.save_path session.save_path defines the argument which is passed to the save handler. If you choose the default files handler, this is the path where the files are created. Defaults to /tmp.
upload_max_filesize The maximum size of an uploaded file.
