Can you please guide me how can I convert an image from a URL to base64 encoding?

Use also this way to represent image in base64 encode format...
find PHP function file_get_content
and next to use function base64_encode
and get result to prepare str as data:" . file_mime_type . " base64_encoded string
. Use it in img src attribute. see following code can I help for you.
// A few settings
$img_file = 'raju.jpg';
// Read image path, convert to base64 encoding
$imgData = base64_encode(file_get_contents($img_file));
// Format the image SRC: data:{mime};base64,{data};
$src = 'data: '.mime_content_type($img_file).';base64,'.$imgData;
// Echo out a sample image
echo '<img src="'.$src.'">';
<img src="data:image/png;base64,<?php echo base64_encode(file_get_contents("IMAGE URL HERE")) ?>">
I was trying to use this resource but kept getting an error, I found the code above worked perfectly.
Just replaced IMAGE URL HERE with the URL of your image - http://www.website.com/image.jpg
Very simple and to be commonly used:
function getDataURI($imagePath) {
$finfo = new finfo(FILEINFO_MIME_TYPE);
$type = $finfo->file($imagePath);
return 'data:'.$type.';base64,'.base64_encode(file_get_contents($imagePath));
}
//Use the above function like below:
echo '<img src="'.getDataURI('./images/my-file.svg').'" alt="">';
echo '<img src="'.getDataURI('./images/my-file.png').'" alt="">';
Note: The Mime-Type of the file will be added automatically (taking help from this PHP documentation).
Here is the code for upload to encode and save it to the MySQL
if (!isset($_GET["getfile"])) {
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br>";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);
$bin_string = file_get_contents($_FILES["file"]["name"]);
$hex_string = base64_encode($bin_string);
$mysqli = mysqli_init();
if (!$mysqli->real_connect('localhost', 'root', '', 'arihant')) {
die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
}
$mysqli->query("INSERT INTO upload(image) VALUES ('" . $hex_string . "')");
}
}
For showing the image use this
echo "<img src='data:image/jpeg;base64, $image' width=300>";
You can also do this via curl, just you need a path to an image file and pass it to the function given below..
public static function getImageDataFromUrl($url)
{
$urlParts = pathinfo($url);
$extension = $urlParts['extension'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, 0);
$response = curl_exec($ch);
curl_close($ch);
$base64 = 'data:image/' . $extension . ';base64,' . base64_encode($response);
return $base64;
}
Here is an example using a cURL call.. This is better than the file_get_contents() function. Of course, use base64_encode()
$url = "http://example.com";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
?>
<img src="data:image/png;base64,<?php echo base64_encode($output);?>">
