file_upload_parser.php：
<?php $fileName = $_FILES["file1"]["name"]; // The file name $fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder $fileType = $_FILES["file1"]["type"]; // The type of file it is $fileSize = $_FILES["file1"]["size"]; // File size in bytes $fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true if (!$fileTmpLoc) { // if file not chosen echo "ERROR: Please browse for a file before clicking the upload button."; exit(); } if(move_uploaded_file($fileTmpLoc, "test_uploads/$fileName")){ echo "$fileName upload is complete"; } else { echo "move_uploaded_file function failed"; } ?>
