how to install php4 on wamp5 1.7.4, any ideas?
BTW, I know how to install php4 addon on WampServer 2.
The only component of WAMP that uses PHP is Apache. Hence it is a standard installation procedure, same as any Apache on Windows. Nearly the same on all os.
Replace PHP5 with PHP4:
# PHP5 #LoadModule php5_module "c:/phpdir/php5apache2_2.dll" #PHPIniDir "C:/phpdir/php-5.2.3-Win32"
# PHP4 LoadModule php4_module "C:/phpdir/php4apache2.dll" PHPIniDir "C:/phpdir"
