I wrote a verification class here to determine the file format through the file header. (It is not 100% safe. If the user forges the file header, it can also pass the verification)

Copy the code The code is as follows:


/**

class FileTypeValidation
{
// 文件类型,不同的头信息
private static $_fileFormats = Array(

调用

复制代码 代码如下:


require './class_filetypevalidation.php';
// 文件路径
$filePath = "D:/test.png";
$x = FileTypeValidation::validation($filePath, 'zip');
var_dump($x);
