PHP can be used to simulate HTTP requests via curl, as well as get HTTP response headers and body, and of course set parameters to get only one of them. When the settings get both the response header and the body, they are returned together as a result. Then we need to separate them ourselves.
The following code is impersonating an HTTP GET request to Google
functionHttpGet() {$url= ' HTTP://WWW.GOOGLE.COM.HK ';$ch=Curl_init();curl_setopt($ch,Curlopt_url,$url);curl_setopt($ch,Curlopt_header,TRUE); Indicates the need to response headercurl_setopt($ch,Curlopt_nobody,FALSE); Indicates the need for response bodycurl_setopt($ch,Curlopt_returntransfer,TRUE);curl_setopt($ch,Curlopt_followlocation,FALSE);curl_setopt($ch,Curlopt_autoreferer,TRUE);curl_setopt($ch,Curlopt_timeout, 120); $result = Curl_exec ($ Ch if (curl_getinfo $ch , Curlinfo_http_code) Span class= "PLN" > == ' ") { return $result } return Null} /span>
When you call the above method, you see an output like this:

Here you can see that the header and body information are together in the results, so how to separate them. There are two ways to get the length of the header by using the Curl_getinfo () method of curl, and then use SUBSTR to split the string. The sample code is as follows:
$response=Curl_exec($ch);If (Curl_getinfo($ch,Curlinfo_http_code) == ' ' ) {= Curl_getinfo ( $ch , Curlinfo_header_size $header = Substr ( $response 0, $headerSize $body = Substr ( $response Span class= "pun" >, $headerSize /span>
The second method is based on the header and body is divided by two carriage return line, so can be implemented by the following code:
$response=Curl_exec($ch);if (curl_getinfo $ch , Curlinfo_http_code) == ' $ ' { List ( $header , $body ) = explode ( "\r\n\r\n" , Response , 2 /span>
