phpuploadCanCommonly usedImethodofSimplekind

A very simple, commonly used PHP method. I took it out from the class for everyone. You can use it directly, or you can continue to improve it. The bkJia video tutorial also explains the PHP upload method in detail. Please refer to it. Just a moment

/**
* Image upload method-source and bkJia Chinese website
* $maxsize=500000 = 500k;
* $updir="up/";
* $upfile=$_FILES["file_img"];
​*/
public function Get_file_upload($upfile, $maxsize, $updir, $newname = date) {

if ($newname == date)
$newname = date("Ymdhs"); //Use date as file name
$name = $upfile["name"];
$type = $upfile["type"];
$size = $upfile["size"];
$tmp_name = $upfile["tmp_name"];

switch ($type) {
case image/pjpeg :
case image/jpeg :
$extend = ".jpg";
Break;
case image/gif :
$extend = ".gif";
Break;
case image/png :
$extend = ".png";
Break;
}
if (empty ($extend)) {
The echo file type is incorrect, only JPG GIF PNG format can be used;
}
if ($size > $maxsize) {
$maxpr = $maxsize / 1000;
echo "Warning! The uploaded image size cannot exceed";
}
if (move_uploaded_file($tmp_name, $updir . $newname . $extend)) {
Return $newname . $extend;
}
}

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

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),
