POSIX Functions

This function group exists to allow PHP programmers access to POSIX functions which are not represented by other function groups in PHP. This group also contains a few functions which are not actually defined in POSIX; these are marked where appropriate.

This extension is compiled into PHP by default; however, you may add the --disable-posix option to the configure line when building PHP to prevent inclusion of these functions.
