Are there specific DLL files that need to be copied to the Windows System directory when installing PHP5, and how does this impact extension functionality?

When installing PHP5 on Windows, specific DLL files need to be copied to the Windows System directory in order for certain extensions to function properly. This is because PHP extensions are typically implemented as DLL files that need to be loaded by the PHP interpreter. By ensuring that the necessary DLL files are in the System directory, PHP will be able to locate and load the extensions correctly. 

// Example code snippet to copy necessary DLL files to the Windows System directory
$sourceDir = 'C:\path\to\php\ext'; // Directory where PHP DLL files are located
$destinationDir = 'C:\Windows\System32'; // Windows System directory

$extensionDLLs = ['php_curl.dll', 'php_mysql.dll', 'php_mysqli.dll']; // List of extension DLL files

foreach ($extensionDLLs as $dll) {
    if (file_exists($sourceDir . DIRECTORY_SEPARATOR . $dll)) {
        copy($sourceDir . DIRECTORY_SEPARATOR . $dll, $destinationDir . DIRECTORY_SEPARATOR . $dll);
        echo "Copied $dll to $destinationDir\n";
    } else {
        echo "Error: $dll not found in $sourceDir\n";
    }
}
