PHP settings ​

Finding the correct php.ini ​

Create a temporary PHP file (for example info.php) in your NADA web folder:

php
<?php phpinfo(); ?>

Open it in the browser and note Loaded Configuration File. Edit that php.ini, then delete info.php from the server.

PHP info

File upload limits ​

By default PHP often allows only small uploads (for example 2MB). For large data files, raise both of these together:

ini
upload_max_filesize = 800M
post_max_size = 800M

post_max_size must be at least as large as upload_max_filesize.

Time zone ​

Set your site’s time zone (list of time zones):

ini
date.timezone = "America/New_York"

Execution time and memory ​

ini
max_execution_time = 300
memory_limit = 128M

Increase further if large imports or API jobs time out.

Enable PHP extensions ​

NADA requires:

  • xsl
  • xml
  • mbstring
  • mysqli — if using MySQL or MariaDB
  • sqlsrv — if using Microsoft SQL Server (Install with SQL Server)

Use the extension that matches your database choice (MySQL/MariaDB or SQL Server — not both required).

Minimum PHP version: 7.4 · Recommended: PHP 8.x

Windows ​

Recommended: use PHP Manager for IIS to register PHP and enable extensions — see Installation (Windows) — Install PHP.

You can also edit php.ini directly. Enable extensions with .dll names (exact names depend on your PHP build):

ini
extension=php_xsl.dll
extension=php_mbstring.dll
extension=php_mysqli.dll

Restart IIS or recycle the app pool after saving (or use PHP Manager’s refresh). See Installation (Windows).

Linux ​

Prefer your distribution’s packages / phpenmod, for example:

bash
sudo apt install php-xsl php-xml php-mbstring php-mysql
# or enable modules if already installed:
sudo phpenmod xsl mbstring mysqli
sudo systemctl restart apache2

If you edit php.ini directly, module lines typically look like:

ini
extension=xsl
extension=mbstring
extension=mysqli

See Installation (Linux).
