The `clear_var` function is a built-in function in the PHP template library that helps to remove or clear any data previously set in a variable. This function is useful when trying to reset a variable or when one wants to ensure that there is no data contained in a variable.
Example 1:
`$name = "John Doe";`
``
In the above example, the variable `$name` is set to the value `John Doe`. Then, the `clear_var` function is used to clear the value in the variable. After the function is executed, the variable `$name` will have no value.
Example 2:
``
`
`
`
Age:
`
``
``
`
`
In this example, the variable `$age` is set to the value `25`. The age is displayed using the `echo` statement inside a paragraph tag within a div. There is a button which when clicked, calls the `clear_var` function to clear the value in the `$age` variable. After the button is clicked, the value of `$age` will no longer be displayed in the paragraph tag.
The `clear_var` function is part of the PHP standard library and does not require any specific package.
