Depending on the PHP version, curl simulates the form upload method differently

Before php5.5

$curl = Curl_init (), if (Defined (' Curlopt_safe_upload ')) {  curl_setopt ($curl, Curlopt_safe_upload, false);} $data = Array (' file ' = ' @ '. Realpath ($path));//' @ ' symbol tells the server to upload resources curl_setopt ($curl, Curlopt_url, $url); curl_setopt ($ Curl, Curlopt_post, 1); curl_setopt ($curl, Curlopt_postfields, $data); curl_setopt ($curl, Curlopt_returntransfer, 1); curl_setopt ($curl, Curlopt_useragent, "TEST"), $result = Curl_exec ($curl); $error = Curl_error ($curl);

After php5.5, to PHP7

$curl = Curl_init (); curl_setopt ($curl, Curlopt_safe_upload, true); $data = Array (' file ' = ' = ' = new \curlfile (Realpath ($ path)); Url_setopt ($curl, Curlopt_url, $url); curl_setopt ($curl, Curlopt_post, 1); curl_setopt ($curl, Curlopt_ Postfields, $data); curl_setopt ($curl, Curlopt_returntransfer, 1); curl_setopt ($curl, Curlopt_useragent, "TEST"); $ result = Curl_exec ($curl); $error = Curl_error ($curl);

A compatible method is provided below:

$curl = Curl_init (), if (class_exists (' \curlfile ')) {curl_setopt ($curl, Curlopt_safe_upload, true); $data = Array (' file ' = = new \curlfile (Realpath ($path)))//>=5.5} else {if (defined (' Curlopt_safe_upload ')) {  curl_setopt ($curl, Curlopt_safe_upload, false); } $data = Array (' file ' = ' @ '. Realpath ($path));//<=5.5}curl_setopt ($curl, Curlopt_url, $url); curl_setopt ($curl, Curlopt_post, 1); curl_setopt ($curl, Curlopt_postfields, $data); curl_setopt ($curl, Curlopt_returntransfer, 1); Curl_ Setopt ($curl, Curlopt_useragent, "TEST"), $result = Curl_exec ($curl); $error = Curl_error ($curl);

which

$path: The address of the image to be uploaded

$url: Destination server address

For example

$url = "http://localhost/upload.php"; $path = "/bg_right.jpg"

upload.php Example:

<?php  file_put_contents (Time (). ". JSON ", Json_encode ($_files));  $tmp _name = $_files[' file ' [' Tmp_name '];  $name = $_files[' file ' [' name '];  Move_uploaded_file ($tmp _name, ' audit/'. $name);? >
