Save image from url with curl PHP

To save an image from a URL using PHP and cURL, you can use the following function. This snippet requires the curl and gd PHP extensions.

Example: Save an image from a URL using PHP and cURL

<?php

function saveImage($image_url, $image_name)
{
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $image_url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  $data = curl_exec($ch);
  $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  curl_close($ch);

  if ($data === false || $http_code !== 200) {
    return false;
  }

  $image = imagecreatefromstring($data);
  if ($image === false) {
    return false;
  }

  $image_name = preg_replace('/[^A-Za-z0-9\. -]/', '', $image_name);
  imagejpeg($image, $image_name, 100);
  imagedestroy($image);
  return true;
}

To use this function, pass the URL of the image as the first argument and the desired name for the saved image as the second argument. For example:

Example: Save image to the current working directory

<?php

saveImage("http://example.com/image.jpg", "image.jpg");

This will save the image to the current working directory with the specified name. You can also specify a different directory by including the path in the image name. For example:

Example: Save image to a different directory

<?php

saveImage("http://example.com/image.jpg", "/path/to/directory/image.jpg");

Note: The example above uses imagejpeg(), which forces JPEG output. For PNG or GIF images, replace imagejpeg() with imagepng() or imagegif() to preserve transparency and animation.
