Php can act as the sender of the data.

Simple get

$ch = curl_init (); curl_setopt ($ch, CURLOPT_URL, "http://SomeDomain/SamplePath?SomeVar=test");curl_exec($ch);curl_close($ch);"

two。 Simple post

$ch = curl_init (); curl_setopt ($ch, CURLOPT_URL, "http://SomeDomain/SamplePath");curl_setopt($ch, CURLOPT_POST, true); / / enable POSTcurl_setopt ($ch, CURLOPT_POSTFIELDS, http_build_query (array (" a "= >" 123", "b" = > "321")); curl_exec ($ch); curl_close ($ch)

3. Advanced post, which can set multiple parameters

$toURL = "http://SomeDomain/SamplePath?SomeVar=XX";$post = array (" a "= >" 123", "b" = > "321",); $ch = curl_init (); $options = array (CURLOPT_URL= > $toURL, CURLOPT_HEADER= > 0, CURLOPT_VERBOSE= > 0, CURLOPT_RETURNTRANSFER= > true, CURLOPT_USERAGENT= > "Mozilla/4.0 (compatible;)", CURLOPT_POST= > true, CURLOPT_POSTFIELDS= > http_build_query ($post),); curl_setopt_array ($ch, $options) / / CURLOPT_RETURNTRANSFER=true will return the server response code, and / / false will only return the success or failure $result = curl_exec ($ch); curl_close ($ch); echo $result

4. Post sends files

Sender code:

$target_url = 'https://cache.yisu.com/upload/information/20200310/52/110483.jpg'); / * curl will accept an array here too. * Many examples I found showed a url-encoded string instead. * Take note that the 'key' in the array will be the key that shows up in the * $_ FILES array of the accept script. And the at sign'@'is required before the * file name. * / $post = array ('extra_info' = >' 123456'. File_name_with_full_path); $ch = curl_init (); curl_setopt ($ch, CURLOPT_URL,$target_url); curl_setopt ($ch, CURLOPT_POST,1); curl_setopt ($ch, CURLOPT_POSTFIELDS, $post); curl_setopt ($ch, CURLOPT_RETURNTRANSFER,1) $result=curl_exec ($ch); curl_close ($ch); echo $result

Receiver code:

Uploaddir = realpath ('. /'). '/'; $uploadfile = $uploaddir. Basename ($_ FILES ['file_contents'] [' name']); echo''; if (move_uploaded_file ($_ FILES ['file_contents'] [' tmp_name'], $uploadfile)) {echo "File is valid, and was successfully uploaded.\ n";} else {echo "Possible file upload attack!\ n";} echo 'Here is some more debugging info:' Print_r ($_ FILES); echo "\ n\ n"; print_r ($_ POST); print "\ n"; these are all the contents of the article "how php curl sends get or post requests".
