This article mainly shows you "how php curl sends get or post requests". The content is simple and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how php curl sends get or post requests".

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".
