How do I modify the path used by exec in php

Question

There are some scripts that need certain paths to be set in environment to run. I want to edit my path to include those locations. These are the locations I want to add to my exec path.

 $JAVA_HOME = "/usr/java/jdk1.6.0_31";
 $ANT_HOME = "/usr/apache-ant-1.8.3";
 $ANT_BIN = "$ANT_HOME/bin";
 $JAVA_BIN = "$JAVA_HOME/bin";
 $ADDPATH=$JAVA_HOME . ":" . $ANT_HOME . ":" . $ANT_BIN .":" . $JAVA_BIN . ":" . $PATH;

And i used putenv

 putenv("JAVA_HOME=" . $JAVA_HOME);
 putenv("ANT_HOME=" . $ANT_HOME);
 putenv("ANT_BIN=" . $ANT_BIN);
 putenv("JAVA_BIN=" . $JAVA_BIN);
 putenv("PATH=".$_ENV["PATH"].":".$ADDPATH);

However when I do a

echo getenv("PATH");

i get

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

I have two queries : (a) How do I set the path variable to the values I want (b) Is there a way ( or a location ) to add these locations to be a part of server environment ( within php.ini or apache configs ) rather than use the script to make these edits.

Answer 1

Try to use apache_setenv() and apache_getenv().
