The basic requirements include: 1. The length is no less than 8 digits; 2. At least containing lowercase letters, uppercase letters, and numbers; 3. Special character restrictions can be added; in terms of advanced aspects, continuous duplication of characters and incremental/decreasing sequences need to be avoided, which requires PHP function detection; at the same time, blacklists should be introduced to filter common weak passwords such as password and 123456; finally it is recommended to combine the zxcvbn library to improve the evaluation accuracy. How to combine two php arrays unique values? Jul 02, 2025 pm 05:18 PM To merge two PHP arrays and keep unique values, there are two main methods. 1. For index arrays or only deduplication, use array_merge and array_unique combinations: first merge array_merge($array1,$array2) and then use array_unique() to deduplicate them to finally get a new array containing all unique values; 2. For associative arrays and want to retain key-value pairs in the first array, use the operator: $result=$array1 $array2, which will ensure that the keys in the first array will not be overwritten by the second array. These two methods are applicable to different scenarios, depending on whether the key name is retained or only the focus is on PHP Variable Scope Explained Jul 17, 2025 am 04:16 AM Common problems and solutions for PHP variable scope include: 1. The global variable cannot be accessed within the function, and it needs to be passed in using the global keyword or parameter; 2. The static variable is declared with static, and it is only initialized once and the value is maintained between multiple calls; 3. Hyperglobal variables such as $_GET and $_POST can be used directly in any scope, but you need to pay attention to safe filtering; 4. Anonymous functions need to introduce parent scope variables through the use keyword, and when modifying external variables, you need to pass a reference. Mastering these rules can help avoid errors and improve code stability. How to handle File Uploads securely in PHP? Jul 08, 2025 am 02:37 AM To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data. Commenting Out Code in PHP Jul 18, 2025 am 04:57 AM There are three common methods for PHP comment code: 1. Use // or # to block one line of code, and it is recommended to use //; 2. Use /.../ to wrap code blocks with multiple lines, which cannot be nested but can be crossed; 3. Combination skills comments such as using /if(){}/ to control logic blocks, or to improve efficiency with editor shortcut keys, you should pay attention to closing symbols and avoid nesting when using them.

Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4.

Good annotations can reduce communication costs and improve code maintenance efficiency. How to create an array in php? Jul 02, 2025 pm 05:01 PM There are two ways to create an array in PHP: use the array() function or use brackets []. 1. Using the array() function is a traditional way, with good compatibility. Define index arrays such as $fruits=array("apple","banana","orange"), and associative arrays such as $user=array("name"=>"John","age"=>25); 2. Using [] is a simpler way to support since PHP5.4, such as $color See all articles <strong id="ot9qz"><strong id="ot9qz"><legend id="ot9qz"></legend></strong></strong><pre id="ot9qz"></pre><cite id="ot9qz"><thead id="ot9qz"></thead></cite>
