本文实例讲述了php+html5+ajax实现上传图片的方法。分享给大家供大家参考，具体如下：
<?phpif (isset($_POST['upload'])) { var_dump($_FILES); move_uploaded_file($_FILES['upfile']['tmp_name'], 'up_tmp/'.time().'.dat'); //header('location: test.php'); exit;}?> <!doctype html><html lang="zh"><head> <meta charset="utf-8"> <title>HTML5 Ajax Uploader</title> <script src="jquery-2.1.1.min.js"></script></head><body><p><input type="file" id="upfile"></p><p><input type="button" id="upJS" value="用原生JS上传"></p><p><input type="button" id="upJQuery" value="用jQuery上传"></p><script> /*原生JS版*/ document.getElementById("upJS").onclick = function() { /* FormData 是表单数据类 */ var fd = new FormData(); var ajax = new XMLHttpRequest(); fd.append("upload", 1); /* 把文件添加到表单里 */ fd.append("upfile", document.getElementById("upfile").files[0]); ajax.open("post", "test.php", true); ajax.onload = function () { console.log(ajax.responseText); }; ajax.send(fd); } /* jQuery 版 */ $('#upJQuery').on('click', function() { var fd = new FormData(); fd.append("upload", 1); fd.append("upfile", $("#upfile").get(0).files[0]); $.ajax({ url: "test.php", type: "POST", processData: false, contentType: false, data: fd, success: function(d) { console.log(d); } }); });</script></body></html>
