file_put_contents() or similar to create new photo - php

Question

I receive a string of base64 and am able to decode it and put it into a file. The problem is, I would like to create a new image file each time to put this base64 into.
Currently I have a basic code which is able to put contents into the file that is pre-existing but the current code does not create a non-existent file.
$data = base64_decode($data);
$path = 'abc';
var_dump(is_dir($path));
if ( ! is_dir($path)) {
if(mkdir($path, 0777)) {
echo "created dir";
}
}
file_put_contents('tmp.png', $data);

Answer 1

Base64 function to decode
function base64ToFile($base64String, $outputFile) {
$file = fopen($outputFile, "wb");
$data = explode(',', $base64String);
fwrite($file, base64_decode($data[1]));
fclose($file);
return $outputFile;
}

Check this the function will return you the unique name after uploading your image in a directory
$imageBase64=$_POST['image_converted_base64'];//get base64 of image from client end
$unique_name =uploadSingleImage($imageBase64);//function call
//function to upload image and get an unique name to store in db
function uploadSingleImage($base64) {
$uniname = uniqid() . date("Y-m-d-H-i-s") . ".png";
$new_image_url = "../../image/" . $uniname;
$base64 = 'data:image/jpeg;base64,' . $base64;
$base64 = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $base64));
file_put_contents($new_image_url, $base64);
return $uniname;
}
