Decoding a Gzipped Web Page Retrieved via cURL in PHP

When retrieving a gzipped web page using cURL, extracting the actual content can be challenging if it appears in raw form. PHP offers a better solution than manually decompressing the data through a temporary file.

Solution:

The key lies in configuring cURL's "auto encoding" mode. This enables cURL to communicate its support for different encoding methods (via the Accept-Encoding header) and automatically handle the decompression process. To activate this mode, use the following code:

<code class="php">// Allow cURL to use gzip compression or any other supported encoding
// A blank string activates 'auto' mode
curl_setopt($ch, CURLOPT_ENCODING, '');</code>

Alternatively, to specify a specific encoding (gzip only), use this command:

<code class="php">// Allow cURL to use gzip compression
curl_setopt($ch, CURLOPT_ENCODING, 'gzip');</code>

This simple adjustment will let cURL automatically decompress the gzipped web page, providing you with the decoded content directly. Refer to the PHP documentation for more information on curl_setopt.
