PHP - Get base64 in data - php

Question

How can I get the base64 value properly in PHP from a submitted data?
The data being passed on is
data:image/png;base64,LongBase64ValueHereOfAnImage
Right now, I can only get it by
$data = $_POST['image'];
list($type, $data) = explode(';', $data);
list($data) = explode(',', $data);
$data = base64_decode($data);
Is there a proper way to get the base64 value?

Answer 1

This could be done in one line with regex
$data = $_POST['image'];
$data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data));

Answer 2

try this: uploading image code.
if (count($_FILES) > 0) {
if (is_uploaded_file($_FILES['image']['tmp_name'])) {
$conn = mysqli_connect('localhost', 'username', 'password', 'databasename');
$imgData = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$imageProperties = getimageSize($_FILES['image']['tmp_name']);
$sql = "INSERT INTO upload(image) VALUES('$imgData')";
$current_id = mysqli_query($conn, $sql) or die("<b>Error:</b> Problem on Image Insert<br/>" . mysqli_error($conn));
if (isset($current_id)) {
echo 'done';
}
}
}
And then get data using base64
$sql = "SELECT * FROM upload WHERE id = 113";
$sth = $conn->query($sql);
$result = mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,' . base64_encode($result['image']) . '"/>';
