What are the best practices for reusing variables in PHP scripts?

When reusing variables in PHP scripts, it is important to ensure that the variable is properly reset or cleared before assigning a new value to it. This prevents any unintended data contamination or unexpected behavior in the script. One common practice is to use unset() function to clear the variable before reusing it. 

// Clearing the variable before reusing it
$myVar = "First Value";

// Do something with $myVar

unset($myVar);

$myVar = "Second Value";

// Now $myVar is ready to be used with a new value
