![]() it returns parsed query as associative array. ![]() ![]() If you need custom arg separator, you can use this function. As an alternative, I use a "proper" querystring parser function: This can be confusing for anyone who's used to the CGI standard, so keep it in mind. Instead, PHP uses a non-standards compliant practice of including brackets in fieldnames to achieve the same effect. If multiple fields of the same name exist in a query string, every other web processing language would read them into an array, but PHP silently overwrites them: Instead, we could use the respective subject’s names as the keys in our associative array, and the value would be their. For example, to store the marks of different subject of a student in an array, a numerically indexed array would not be the best choice. It bears mentioning that the parse_str builtin does NOT process a query string in the CGI standard way, when it comes to duplicate fields. Associative arrays are used to store key value pairs. 2) Using PHP arraykeys() function with an associative array example.
