PHP Fatal error: Cannot redeclare a function previously declare in another file.

Question

I have a sub-domain of the main domain which seems to be broken. The error states that "Server IP Address could not be found".

When I checked the logs I found the following error:

[04-Jun-2018 17:54:43 UTC] PHP Fatal error:  Cannot redeclare is_writeable_ACLSafe() (previously declared in /home/testcompany/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase2.php:1009) in 

/home/testcompany/training.testcompany/wp-content/plugins/wp-super-cache/wp-cache.php on line 102

Line#102 belonging to the section

/home/thebettersoftwar/training.thebettersoftwarecompany.com/wp-content/plugins/wp-super-cache/wp-cache.php

function is_writeable_ACLSafe($path) {

    // PHP's is_writable does not work with Win32 NTFS

    if ($path{strlen($path)-1}=='/') // recursively return a temporary file path
        return is_writeable_ACLSafe($path.uniqid(mt_rand()).'.tmp');
    else if (is_dir($path))
        return is_writeable_ACLSafe($path.'/'.uniqid(mt_rand()).'.tmp');
    // check tmp file for read/write capabilities
    $rm = file_exists($path);
    $f = @fopen($path, 'a');
    if ($f===false)
        return false;
    fclose($f);
    if (!$rm)
        unlink($path);
    return true;
}

The code belonging to this section

previously declared in /home/thebettersoftwar/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase2.php:1009 is:

function is_writeable_ACLSafe( $path ) {

    // PHP's is_writable does not work with Win32 NTFS

    if ( $path[ strlen( $path ) - 1 ] == '/' ) { // recursively return a temporary file path
        return is_writeable_ACLSafe( $path . uniqid( mt_rand() ) . '.tmp' );
    } elseif ( is_dir( $path ) ) {
        return is_writeable_ACLSafe( $path . '/' . uniqid( mt_rand() ) . '.tmp' );
    }

    // check tmp file for read/write capabilities
    $rm = file_exists( $path );
    $f = @fopen( $path, 'a' );
    if ( $f === false )
        return false;
    fclose( $f );
    if ( ! $rm ) {
        unlink( $path );
    }

    return true;
}

Problem Statement:

I am wondering what changes I should make in the code above so that I am able to run the website live again.

Wrap the function declaration in https://secure.php.net/manual/en/function.function-exists.php — castis, Jun 04 '18 at 18:56
@castis I know its a duplicate but I wasn't able to get my answer. — flash, Jun 04 '18 at 19:01
`if (!function_exists('is_writeable_ACLSafe')) { put function code in here }` — Danny, Jun 04 '18 at 19:02
I do not know the order of includes so just wrap it around both. It will run the first time it's found since the function is not found and then not run the second time since it's been created whatever the order of includes are. — Danny, Jun 04 '18 at 19:09
By the looks of it both of these functions are declared in the source of wp-super-cache. I'd suggest re-installing the plugin as it seems to me like you've updated half the files and that function was moved from one file to another somewhere a long the line. — Arcath, Jun 06 '18 at 14:50
