php curl request information and return information setting code examples

This article mainly introduces php curl request information and return information setting code examples. This article directly gives code examples. Need Friends can refer to it

When using curl to capture web page content, you often need to know the request header information returned by the web page and the relevant information of the request, especially when there is a redirection during the request process, obtaining the request return header information is helpful for analyzing the request content. Very helpful

The following is an example of a redirection in a request. Our purpose is to obtain the url address of the final actual request

You can see that after a recursive request, you finally get a response of 200, but this method cannot get the URL of the last request, which is the final URL of the actual request. To get this URL, you need to recursively analyze each request. Returned response

The following is a recursive function I wrote to get the last request URL
