Is it recommended to transfer files using base64 encoding in PHP AJAX requests?

Transferring files using base64 encoding in PHP AJAX requests is not recommended for large files as it can significantly increase the size of the data being transferred. It is more efficient to use FormData objects in AJAX requests to send files without encoding them in base64. This method allows for faster transfer speeds and reduces the risk of running into memory limitations. 

// Create a new FormData object
$formData = new FormData();

// Append the file to be uploaded to the FormData object
$formData->append('file', fileInputElement.files[0]);

// Make an AJAX request with the FormData object
$.ajax({
    url: 'upload.php',
    type: 'POST',
    data: formData,
    processData: false,
    contentType: false,
    success: function(response) {
        console.log('File uploaded successfully');
    },
    error: function(xhr, status, error) {
        console.error('Error uploading file');
    }
});
