Get Headers And Content Of A URL Using Single CURL Request In PHP

Get-Headers-And-Content-Of-A-URL-Using-Single-CURL-Request-In-PHP
A common question is that Is there any way to get both headers and body for a cURL request using PHP? or Can PHP cURL retrieve response headers AND body in a single request?

When an HTTP request has been received by a server, typically the response is sent back to the client. In the case of web resources, the response will usually consist of two parts, the Response Header, and the Response Body.

The header part of the response contains all the response headers, including cookies (if any) and information about the mime type of the content. The response body contains the content, which should match the mine-type in the headers. For example, common mime-types might be text/html for HTML pages, and text/css for external StyleSheets.

There is no build-in way to only return the response headers using cURL in PHP. However, we can still “cut” them from the full response. To do this, we first determine the size of the response header, and then simply cut it from the response using the strings function.

So Are you looking for a PHP script to get Headers and Content of a URL using a single cURL request in PHP? This tutorial will provide a code snippet that will help you to get Headers and Content of a URL from a given website.
