如果太大，PHP 上传会失败？ [复制]

Question

所以我使用 recorder.js 来捕获一些音频，然后我使用此代码将音频上传到我们的服务器：

	var url = URL.createObjectURL(blob);
	var au = document.createElement('audio');
	var li = document.createElement('li');
	var link = document.createElement('a');
	
	//name of .wav file to use during upload and download (without extendion)
	var filename = "test";

	//add controls to the <audio> element
	au.controls = true;
	au.src = url;

	//save to disk link
	link.href = url;
	link.download = filename+".wav"; //download forces the browser to donwload the file using the  filename
	link.innerHTML = "Save to disk";

	//add the new audio element to li
	li.appendChild(au);
	
	//add the filename to the li
	li.appendChild(document.createTextNode(filename+".wav "))

	//add the save to disk link to li
	li.appendChild(link);
	
	//upload link
		  var xhr=new XMLHttpRequest();
		  xhr.onload=function(e) {
		      if(this.readyState === 4) {
		          console.log("Server returned: ",e.target.responseText);
				  Redirect();
		      }
		  };
		  var fd=new FormData();
		  fd.append("audio_data",blob, filename);
		  xhr.open("POST","upload_audio.php",false);
		  xhr.send(fd);

这里是 PHP：

  
<?php
print_r($_FILES); //this will print out the received name, temp name, type, size, etc.
$size = $_FILES['audio_data']['size']; //the size in bytes
$input = $_FILES['audio_data']['tmp_name']; //temporary name that PHP gave to the uploaded file
$output = $_FILES['audio_data']['name'].".wav"; //letting the client control the filename is a rather bad idea
//move the file from temp name to local folder using $output name
move_uploaded_file($input, "../data/".$output)
?>

如果您在 30 秒内进行录制，则此脚本可以完美运行。如果录音变大，我们会从服务器获得以下响应：

Server returned:    
Array
(
    [audio_data] => Array
        (
            [name] => QA_3_Issue,html,7fac7e13c55a4eb18b0f2160f8581097_7fac7e13c55a4eb18b0f2160f8581097
            [type] => 
            [tmp_name] => 
            [error] => 1
            [size] => 0
        )

)

有人知道发生了什么吗？可能是服务器问题？ 我也不太明白为什么它说错误，但没有说明错误到底是什么。

最好的问候， 丹尼尔

您应该在 .htaccess 文件或 php.ini 文件中设置更大的文件大小以进行上传，例如 upload_max_filesize = 100M。 希望，这会有所帮助。
