Are there any security implications to consider when determining the path to PHP in a script?

When determining the path to PHP in a script, it is important to ensure that the path is secure to prevent potential security vulnerabilities, such as allowing unauthorized access or execution of malicious code. One way to address this issue is to use an absolute path to the PHP executable in your script, rather than relying on a relative path or environment variables.

// Use absolute path to PHP executable to ensure security
$phpPath = '/usr/bin/php';
