The $_GET superglobal in PHP is an associative array.
- TRUE
- FALSE
The statement is true. In PHP, the $_GET superglobal is indeed an associative array. It contains key-value pairs where the keys represent the parameters or names of the variables passed through the URL's query string, and the corresponding values are the data associated with those keys. You can access this data using the $_GET['parameter'] syntax, where 'parameter' is the name of the key. Learn more: https://www.php.net/manual/en/reserved.variables.get.php
You are debugging a PHP script and a variable is not retaining its value between function calls. What might be the problem and how would you solve it?
- The variable is declared as a local variable inside the function.
- The variable is declared with the static keyword inside the function.
- The variable is declared as a global variable outside of any function.
- The variable is not properly initialized or assigned values.
If a variable is not retaining its value between function calls, the possible problem might be that the variable is declared with the static keyword inside the function. The static keyword makes the variable retain its value between multiple calls to the same function. To solve this, you can remove the static keyword if the variable doesn't need to retain its value. Alternatively, if the variable should retain its value, make sure it is properly initialized and assigned values.
