Check PHP syntax

check_php_syntax

#!/bin/bash

# Usage: check_php_syntax [directory1] [directory2] ... [directoryN]
#
# This script checks the syntax of all PHP files within the provided directories.
# If no directories are specified, it checks the current directory by default.
#
# Example usage:
#   check_php_syntax                                # Check PHP files in the current directory
#   check_php_syntax /path/to/dir1                  # Check PHP files in a single directory
#   check_php_syntax /path/to/dir1 /path/to/dir2    # Check PHP files in multiple directories
#
# The script uses `php -l` to check the syntax of each PHP file and outputs
# whether the file has any syntax errors or not.

# Check if at least one directory is provided, otherwise use the current directory
if [ $# -eq 0 ]; then
    echo "No directory paths provided. Using the current directory."
