Base64 Encoding for Images from URLs

Question:

How do I obtain a Base64 representation of an image from a URL?

Answer:

To convert an image from a URL into Base64 encoding, utilize the following steps:

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

In this code snippet:

1. Path Extraction: $path is defined as the URL or local path to the image.
2. File Type Identification: pathinfo() is used to determine the file extension, which is stored in $type.
3. Content Retrieval: file_get_contents() reads the image binary data and assigns it to $data.
4. Data Encoding: Finally, base64_encode() converts the image data into a Base64 encoded string, which is then combined with the image's file type using a data URI syntax. The result is stored in $base64. This encoded string can then be used for various purposes, such as displaying the image inline in HTML or transmitting it via HTTP.
