In this article, we will see how to download & save the file from the URL in PHP, & will also understand the different ways to implement it through the examples.
Below are the approaches to download file from URL using PHP:
Table of Content
- Using file_get_contents() function
- Using PHP Curl
Using file_get_contents() function
The file_get_contents() function is used to read a file into a string. This function uses memory mapping techniques that are supported by the server and thus enhances the performance making it a preferred way of reading the contents of a file.
Syntax:
file_get_contents($path, $include_path, $context,
$start, $max_length)
Example: This example illustrates the use of file_get_contents() function to read the file into a string.
<?php // Initialize a file URL to the variable $url = 'https://media.geeksforgeeks.org/wp-content/uploads/gfg-40.png'; // Use basename() function to return the base name of file $file_name = basename($url); // Use file_get_contents() function to get the file // from url and use file_put_contents() function to // save the file by using base name if (file_put_contents($file_name, file_get_contents($url))) { echo "File downloaded successfully"; } else { echo "File downloading failed."; }?>
Output:
Before running the program:
php source folder
After running the program:
File downloaded after successful execution
Downloaded image file
Using PHP Curl
The cURL stands for ‘Client for URLs’, originally with URL spelled in uppercase to make it obvious that it deals with URLs. It is pronounced as ‘see URL’. The cURL project has two products libcurl and curl.
Steps to download the file:
- Initialize a file URL to the variable.
- Create cURL session.
- Declare a variable and store the directory name where the downloaded file will save.
- Use the basename() function to return the file basename if the file path is provided as a parameter.
- Save the file to the given location.
- Open the saved file location in write string mode.
- Set the option for cURL transfer.
- Perform cURL session and close cURL session and free all resources.
- Close the file.
Example: This example illustrates the use of the PHP Curl to make HTTP requests in PHP, in order to download the file.
<?php // Initialize a file URL to the variable $url = 'https://media.geeksforgeeks.org/wp-content/uploads/gfg-40.png'; // Initialize the cURL session $ch = curl_init($url); // Initialize directory name where // file will be save $dir = './'; // Use basename() function to return // the base name of file $file_name = basename($url); // Save file into file location $save_file_loc = $dir . $file_name; // Open file $fp = fopen($save_file_loc, 'wb'); // It set an option for a cURL transfer curl_setopt($ch, CURLOPT_FILE, $fp); curl_setopt($ch, CURLOPT_HEADER, 0); // Perform a cURL session curl_exec($ch); // Closes a cURL session and frees all resources curl_close($ch); // Close file fclose($fp);?>
Output:
Before running the program:
php source folder
After running the program:
Downloaded image file
