Why am i encountering 'cannot redeclare function in php'?

Example:

function duplicate() {
    // some code
}
function duplicate() {
    // some code
}

Defining the same function multiple times in your script or including it from external sources.

Solution:

Ensure that functions are uniquely named throughout your application. Utilize PHP's include_once or require_once to avoid including files multiple times.


// Use unique function names
// Use include_once or require_once
