Downloading Large Files with Curl: An Alternative to Reading into Memory

Question: How can one overcome the memory constraints when downloading large files using curl, which typically reads into memory?

This issue arises in situations where the file size exceeds the available memory on the server. A more efficient approach is to stream the file directly to disk, bypassing memory entirely.

Answer:

In this code, the following modifications are key:

• curl_setopt($ch, CURLOPT_FILE, $fp); specifies the target file for the download, enabling direct streaming to disk.
• curl_setopt($ch, CURLOPT_TIMEOUT, 600); ensures sufficient time for large file downloads.
• set_time_limit(0); prevents premature termination due to server timeouts.
