PHP4 configuration file php.ini annotations and configuration instructions

Throughout the file, in order to keep the original file from being corrupted, I took the following way

1, can be directly annotated, in the ";" after adding.

2, if it is not easy to annotate directly, then add another, but all with ";;" Start

The "Boolean" flag in the file can be the following value
Open: 1 or on or True or Yes;
OFF: 0 or off or False or No
