php文件上传的问题
我用php写了一个简单的文件上传的页面,显示上传成功了,但
(1)、对应目录下却没有上传的文件【tmp目录下没有文件,也没有生成upload目录和文件】。
(2)、move_uploaded_file的参数顺序,代码中上一行的为错误的,下一行正确,与教材上的相反。
求大神解惑。
upload.html
<br /><form action = "upload_file.php" method = "post" enctype = "multipart/form-data"><br /><label for = "file">Filename</label><br /><input type = "file" name = "file" id = "file"/><br /><br><br /><input type = "submit" name = "submit" value = "上传"/><br /><br /></form><br />
upload.php
<br /><?php<br />if($_FILES["file"]["error"] > 0)<br />{<br /> echo "Error : ".$_FILES["file"]["error"]."<br>";<br />}<br />else<br />{<br /> echo "Upload: ".$_FILES["file"]["name"]."<br>";<br /> echo "Type: ". $_FILES["file"]["type"]."<br>";<br /> echo "Size: ".($_FILES["file"]["size"]/1024)."KB<br>";<br /> echo "Stored in: ".$_FILES["file"]["tmp_name"]."<br>";<br /> <br /> if(file_exists("upload/".$_FILES["file"]["name"]))<br /> {<br /> echo $_FILES["file"]["name"]." already exists.";<br /> }<br /> else<br /> {<br /> //move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$_FILES["file"]["name"]);// 报错<br /> move_uploaded_file("upload/".$_FILES["file"]["name"],$_FILES["file"]["tmp_name"]);<br /> echo "<br><br><br> Storeed in: "."upload/".$_FILES["file"]["name"];<br /> }<br /> <br /><br />}<br /><br /><br /><br />?><br />

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
