How to Resolve "Fatal error: Maximum function nesting level of '100' reached, aborting!" in PHP

When dealing with recursive functions, it's common to encounter this error, especially when the recursion is performed for a significant number of times. In PHP, the default maximum function nesting level is set to 100 for security reasons.

To resolve this issue in your specific case, you can adjust the maximum function nesting level in your php.ini configuration file. Here are the steps to follow:

1. Locate php.ini: The php.ini file is typically located in the following paths:

   • Windows: C:Windowsphp.ini
   • Linux: /etc/php.ini
2. Find xdebug.max_nesting_level: Open the php.ini file and search for the xdebug.max_nesting_level directive.
3. Increase the value: By default, xdebug.max_nesting_level is set to 100. To increase this limit, edit the line and provide a higher value. For example, you can set it to 500 or 1000.
4. Save the changes: Save the php.ini file and restart your web server for the changes to take effect.

Once you've increased the nesting limit, the recursion limit will be extended and your function should be able to run without crashing due to this error.
