Question

how to install php4 on wamp5 1.7.4, any ideas?

BTW, I know how to install php4 addon on WampServer 2.

Answer 1

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.

1. Download PHP4 for Windows.
2. Install or Unzip PHP-files in a PHP-folder like c:\php.
3. Stop Apache.
4. Edit Apache:

  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"
  

1. Make sure you change “C:/phpdir” to wherever you put PHP 4.
2. Start Apache.
