How to Encode and Decode URL Using PHP

admin | Posted on May 14, 2021 |

PHP supports encoding and decoding of URL by providing some built-in functions. Encoding is required before sending URL data to query string or to a function which might dynamically work on this URL data. And then, this data will be decoded into its original form, after receiving it in target PHP page or function.
