在php上使用文件上傳得到錯誤

任何人都可以用我的代碼推斷出什麼可能是問題嗎？當我試圖上傳超過8 MB的PDF文件時，這是我收到的消息：在php上使用文件上傳得到錯誤

出錯了[沒有文件上傳]文件已存在於服務器上。

這是我輸入了代碼：

<?php 
    $name = $_FILES['file']['name']; 
    $storefile_loc = "uploads/"; 
    $storefile_path = $storefile_loc.basename($name); 

    //$get_ext=explode(".",$_FILES['file']['name']); //separates file name from extension 
    //$ext=end($get_ext); //gets the extension from above explosion 
    $txtFileType = pathinfo($storefile_path,PATHINFO_EXTENSION); 
    $goodext = array("txt","doc","odt","docx"); //array of extensions for app 

    //Check if files are .txt (.doc, and .pdf functionality to be added) 
    if (isset($_POST["submit"])){ //checks if form has been submitted 
     //$check=mime_content_type($name); 
     if (($_FILES['file']['type'] == "text/plain") 
     ||($_FILES['file']['type'] == "application/pdf") 
     ||($_FILES['file']['type'] == "application/vnd.oasis.opendocument.text") 
     ||($_FILES['file']['type'] == "application/msword") 
     ||($_FILES['file']['type'] == "application/vnd.openxmlformats-officedocument.wordprocessingml.document") 
     &&(in_array($txtFileType,$goodext))){ 
      echo "Uploading File..."; 
     } 
     else { 
      echo "You can only upload a txt/doc/docx/pdf/odt file."; 
     } 
    } 
    else { 
     echo "Something went wrong [No file uploaded]"; 
    } 

    //Check if file already exists. Probably won't need this 
    if (file_exists($storefile_path)){ //this instead of $name because it's checking server 
     echo "File already on server."; 
    } 

    //Check file size 
    if ($_FILES['file']['size'] > 2000000){ 
     echo "File is too large."; 
    } 


    //Way to upload permanently. Probably won't need this 
    /* 
    if (move_uploaded_file($_FILES['file']['tmp_name'], $storefile_path)){ 
     echo "The file '".basename($_FILES['file']['name'])."' has been uploaded."; 
    } 
    else { 
     echo "Something went wrong when uploading your file."; 
    } 
    */ 

    ?>

我也得上線2的36是我的代碼問題通知的錯誤？還是與Apache？

首先檢查'upload_max_filesize'和'post_max_size'大於'8MB' –

什麼錯誤和什麼是在這些行上，'我也在第2行和第36行發現了錯誤。是否我的代碼存在問題？' – ArtisticPhoenix

嘗試在php.ini中增加這些設置，默認大小（典型值）爲8MB

; Maximum allowed size for uploaded files. 
    upload_max_filesize = 40M; 
    ; Must be greater than or equal to upload_max_filesize 
    post_max_size = 40M;

之後，你必須重新啓動服務器以應用這些設置。

這意味着PHP將您的文件上傳大小限制爲這兩個設置。你可能不需要40M，但你應該增加它，可能是你想要上傳的最大文件的120％，這會給你一點喘息的空間。

這通常是我在我的服務器上配置的第一件事，我通常做的大約80MB，更重要的是，這對我的客戶使用sFTP更簡單。

就是這樣！ Thnx太多了！ – Lloydinator

當然，很高興我能幫助你... – ArtisticPhoenix

你需要添加的通知錯誤行

$name = $_FILES['file']['name'];

和

if ($_FILES['file']['size'] > 2000000){ 
    echo "File is too large."; 
}

到isset（ 'POST'）

if (isset($_POST["submit"])){ 
    $name = $_FILES['file']['name']; 
    ... 
    if ($_FILES['file']['size'] > 2000000){ 
    echo "File is too large."; 
    } 
}
