php regex to validate a phone number
Article Introduction：Verifying regular expressions for phone numbers is not difficult in PHP, but the key is to clarify the format standards of legal phone numbers. 1. Different countries and business scenarios have different requirements for phone number formats, so general regularity is unrealistic; 2. Common formats include pure numbers, area codes, hyphens, international area code beginnings, extension numbers, etc.; 3. PHP uses the preg_match() function to perform regular matching, and rules can be flexibly written according to requirements; 4. When designing regularity, elements such as supporting digits, allowing symbols, whether international area codes are included; 5. Common errors include trying to cover all formats, ignoring boundary conditions, not conducting multi-case tests, and relying on back-end verification only. It is recommended to customize regular expressions according to specific project needs and do two-factor verification before and after.

php function for curl post request
Article Introduction：How to send a POST request in PHP? The answer is to use the cURL library. 1. Initialize the cURL handle; 2. Set the target URL, enable return transmission, enable POST method and specify POST data; 3. Optionally set custom request headers; 4. Execute request and process responses; 5. Check for error information; 6. Close the cURL handle. When sending data, you can use array or JSON format. If it is JSON, you need to manually set the Content-Type header; if HTTPS requests encounter SSL certificate problems, you can turn off verification in the test environment, but the production environment should avoid it. Examples include normal form submission and JSON data submission.
