This script allows you to update a PHP configuration variable for all installed PHP versions on a cPanel/WHM server. It supports both ea-php and alt-php packages provided by CloudLinux.

Features

• Command-line Arguments: The script accepts the PHP configuration variable and its new value as command-line arguments.
• Interactive Mode: If no command-line arguments are provided, the script will prompt for input.
• Validation: Ensures the variable name does not contain spaces and both the variable and value are not empty.
• Preview Changes: Displays a preview of the changes for each PHP version, highlighting current and new values.
• Handling Missing Variables:
  • Warns if the variable is not present in the file and indicates it will be added.
  • If the variable is commented out, it will be uncommented and set to the new value.
  • If the variable does not exist, it will be appended to the end of the file.
• Confirmation Prompt: Asks for user confirmation before applying changes.
• Restart Apache: Automatically restarts Apache to apply the changes.

Usage

./update_php_config.sh [VARIABLE] [NEW_VALUE]

Parameters

• VARIABLE: The PHP configuration variable to change (e.g., post_max_size).
• NEW_VALUE: The new value for the PHP configuration variable (e.g., 64M).

Options

• -h, --help: Display the help message and usage instructions.

Example

To change the post_max_size to 64M for all PHP versions, run:

./update_php_config.sh post_max_size 64M

If no arguments are provided, the script will prompt for the necessary inputs.
