===== upgrade or install PHP =====

Go to [[niota_links | niota download page]] and download the pre configured PHP version or download an approved version from any official PHP download sites.

** 
It's recommended to shut down Apache when you install/upgrade PHP.\\
Don't forget to restart it when you are finished.
**

==== Windows Server ====
Unpack the downloaded PHP-file and copy the unpacked folder to ''C:\Program Files\'' (recommended)

Here we assume a PHP version number 7.3.8_x64. 

**Your PHP version number will be different. Check that you do not just copy the lines from here, but adapt it to you current version numbers.**


  * Copy “php-7.3.8_x64” into folder: “C:\Program Files\”.


==== configure Apache ====
If your Apache is currently running, shut it down!

<code - apache_shutdown.txt>

sc stop Apache24x64_niota

</code>

Open your Apache **''..\conf\httpd.conf''** file and check if PHP settings are made correctly

  * check if PHP path is correct at those lines
      * LoadModule php_module
      * PHPiniDir
  * check that that handler are set
      * AddHandler
      * AddType

<code - apache_phpconfig.txt>

AddHandler application/x-httpd-php .php
AddType application/x-httpd-php .php .html

LoadModule php7_module "C:/Program Files/php-7.3.8_x64/php7apache2_4.dll" 
PHPiniDir "C:/Program Files/ php-7.3.8_x64" 

</code>

After update from Version 7.x  to version 8.y it could look like this:

<code - apache_phpconfig.txt>

AddHandler application/x-httpd-php .php
AddType application/x-httpd-php .php .html

LoadModule php_module "C:/Program Files/php-8.2.18_x64/php8apache2_4.dll"
PHPiniDir "c:/Program Files/php-8.2.18_x64"

</code>

==== configure PHP ====
Navigate to your PHP folder and open **''php.ini''**. 
 
  * Verify if paths are set correctly:
      * session.save_path -- set it to your apache temp directory
      * extension_dir = -- set it to you PHP extension directory 


There are some extions that must be enabled.
- zip - for EXCEL upload
- soap - for Zagreus SOAP calls
- sqlserver in case you need native MS SQL connection
...

<code - phpini_phpconfig.txt>

session.save_path = "c:\Apache24x64\tmp\"
extension_dir = "c:\Program Files\php-8.2.18_x64\ext"

extension=soap
extension=php_zip.dll
extension=php_sqlsrv_82_ts_x64.dll
