php.ini directives – attempt to standarize notation #17266

Description

Currently there are some writing inconsistencies in php.ini directives. Sometimes there are spaces around equals sign (user_ini.cache_ttl = 300), sometimes not (opcache.enable_cli=0). String values are sometimes inside double quotation marks (docref_root = "/phpmanual/") and sometimes not (mbstring.language = Japanese). Finally, boolean values are most often written as On/Off but sometimes they are written as 1/0 or true/false.

The idea is to standarize notation of directives according to some set of rules. For example:

• equals signs should be surrounded by spaces,
• string values should be surrounded by double quotation marks,
• boolean values should be written as On/Off.

Following the above rules, the list of directives would look like this (values taken from production version of php.ini):
