In previous post I explain about install wampserver. This step only install php5 not php4, to add php4 support in wampserver php4 add on must installed first.
Here’s sthe steps :
1. Double click php4 add-on installer
2. Choose destination folder, in previous step I choose C
2. Click Install
2. Installing in progress
you got php4 and php5 in one machine.
by default only one instance php can be run in one session. to change to php4, right click on tray menu and choose
" Switch to PHP4"
