PHP version 4 is no longer supported. The '''only''' reason for downgrading is to match your service provider's version of PHP. They, in turn, should be requesting that you upgrade to version 5.  

== A) Download PHP 4.4.8 ==
Download the full version of PHP 4.4.8

# Create a new folder named '''c:\php448''' (alternatively save the file to any folder)
# Download and save the following file into the above folder:
:# Goto: [http://www.php.net/downloads.php PHP Downloads]
:# Scroll down the page to: Windows Binaries
:# Download this file: '''PHP 4.4.8 zip package''' [8,434Kb] - 12 Feb 2008<br>md5: 09ffff4b1a54bbadb8fee6acd85a2c1f
# '''Right click''' on file and select '''Extract All''', click '''NEXT''' (no need to change path), click '''NEXT''' again.

== B) Install ==
Start with a clean version of Uniform Server 3.5-Apollo and install PHP 4.4.8 as follows:

# '''Extract a new copy of Uniform Server''' to C drive (alternatively you can use any folder or drive)
# '''Start''' and '''stop''' the servers. Make sure they work and train any security software.
# '''Backup php.ini:'''
:# Copy php.ini from C:\Uniform Server\udrive\usr\local\php to C:\Uniform Server
<ol start="4">
<li> '''Install PHP 4.4.8''':
</ol>
:# Delete the contents of folder C:\Uniform Server\udrive\usr\local\php
:# Copy the contents of folder C:\php448\php-4.4.8-Win32\php-4.4.8-Win32<br>To folder: C:\Uniform Server\udrive\usr\local\php
:# Copy php4apache2.dll from: C:\Uniform Server\udrive\usr\local\php\sapi<br>To folder: C:\Uniform Server\udrive\usr\local\php
:# Copy iconv.dll from: C:\Uniform Server\udrive\usr\local\php\dlls<br>To folder: C:\Uniform Server\udrive\usr\local\php
:# Copy libmysql.dll from: C:\Uniform Server\udrive\usr\local\php\dlls<br>To folder: C:\Uniform Server\udrive\usr\local\php
<ol start="5">
<li> '''Restore php.ini''': Copy php.ini from C:\Uniform Server to C:\Uniform Server\udrive\usr\local\phpSave the file to any folder.
</ol>

== C) Edit php.ini ==
Using a text editor, open''' php.ini''' located in folder C:\Uniform Server\udrive\usr\local\php and change the following:

# Locate the line: ''';extension=php_iconv.dll''' and change to  '''extension=php_iconv.dll'''
# Locate the line: '''extension=php_mysql.dll''' and change to  ''';extension=php_mysql.dll'''
# Locate the line: '''extension=php_mysqli.dll''' and change to ''';extension=php_mysqli.dll'''
# Locate the line: '''extension=php_pdo.dll''' and change to      ''';extension=php_pdo.dll'''
# Locate the line: '''extension=php_sqlite.dll''' and change to   ''';extension=php_sqlite.dll'''

== D) Edit httpd.conf ==
Open '''httpd.conf''' located in folder C:\Uniform Server\udrive\usr\local\apache2\conf

<pre>
Locate the line: LoadModule php5_module "/usr/local/php/php5apache2.dll"
Change to:       LoadModule php4_module "/usr/local/php/php4apache2.dll"
</pre>

== E) Edit phpMyAdmin ==
Edit the phpMyAdmin file: '''config.inc.php''' located in folder: C:\Uniform Server\udrive\home\admin\www\phpMyAdmin

<pre>
 Locate the line: $cfg['Servers'][$i]['extension'] = 'mysqli';
 Change to:       $cfg['Servers'][$i]['extension'] = 'mysql';
</pre>

== F) Edit my-small ==
Edit '''my-small''' Located in folder: C:\Uniform Server\udrive\usr\local\mysql\bin

<pre>
  Under this line port=3306 add the following two new lines:

  #Use old password encryption method (needed for 4.0 and older clients).
  old_passwords=1
</pre>

== G) Test - Expected error ==
Restart the servers. From apanel click on '''phpinfo()''' and check that PHP 4.4.8 info is displayed.

Now click '''phpMyAdmin''' (left menu) the following error is expected:
<pre>
#1251 - mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client”
</pre>

'''Reason''':

PHP4 uses short password hashes as opposed to PHP5’s long ones. Anyway it shows PHP4 is working and phpMyAdmin.

To correct the above '''do not turn the servers off''' and follow these instructions:

# Open a command prompt ('''start''' > '''run''' > type '''cmd''' and press '''OK''')
# Type the following and press return at the end of every line:

      '''W:'''
      '''Cd usr\local\mysql\bin'''
      '''mysql -u root –p'''
<ol start="3">
<li> When requested enter the password root
<li> You are now at the MySQL command prompt. Type the following and press return:<br><br>'''SET PASSWORD FOR 'root'@'localhost' =OLD_PASSWORD('root');'''<br><br>Query OK indicates you have created a short password hash.
</ol>
<ol start="5">
<li> Close the command prompt window (top right cross).
<li> Restart the servers; check you can access MySQL using phpMyAdmin.
</ol>

You will need to update phpMyBackupPro:

# From apanel run '''phpMyBackupPro'''
# Login as '''root root''',
# Select the configuration tab:<br>Change the MySQL password to '''root'''<br>Finally click Save Data

That completes the downgrade.
