Data validation library
Upload is a PHP library that handles file upload and verification.
<?php
class FileInfoTest extends PHPUnit_Framework_TestCase
{
protected $fileWithExtension;
protected $fileWithoutExtension;
public function setUp()
{
$this->fileWithExtension = new \Upload\FileInfo(dirname(__FILE__) . '/assets/foo.txt', 'foo.txt');
$this->fileWithoutExtension = new \Upload\FileInfo(dirname(__FILE__) . '/assets/foo_wo_ext', 'foo_wo_ext');
}
public function testConstructor()
{
$this->assertAttributeEquals('foo', 'name', $this->fileWithExtension);
$this->assertAttributeEquals('txt', 'extension', $this->fileWithExtension);
$this->assertAttributeEquals('foo_wo_ext', 'name', $this->fileWithoutExtension);
$this->assertAttributeEquals('', 'extension', $this->fileWithoutExtension);
}We know that in the process of using the language, we will definitely pay attention to the security issues in the actual development process. So, today we will introduce to you the primary measure to ensure PHP security-verification data. Validation of data is the most important habit you can adopt. And when it comes to input, it's very simple: don't trust the user. When validating data to secure PHP, remember that it's often easier to design and validate the values your application allows than to protect against all unknown values.
General validation tips that apply to various types of validation data are listed below:
1. Use values from the whitelist
2. Always re-validate limited options
3. Use the built-in escape function
4. Verify that the correct data type (such as a number)
The value in the white-listed value (White-listed value) is the correct value , as opposed to an invalid blacklist value (Black-listed value). The difference between the two is that typically when validating data, the list or range of possible values is smaller than the list or range of invalid values, many of which may be unknown or unexpected values.
