// This file contains functions that deal with execution of shell commands and provides
|
|
// fixes for 'exec()' on certain win32 systems (based on rivera at spamjoy dot unr dot edu's
|
|
// 'wind_exec()' function <http://php.net/function.exec>).
|
|
|
|
// Note: Since the 'exec()' function is used, some things may not work if
|
|
//'safe_mode' is set to 'On' in your 'php.ini' file. If you need or want to
|
|
// keep 'safe_mode=ON' then you'll need to put the programs within the
|
|
// directory that's specified in 'safe_mode_exec_dir'.
