In the context of PHP, what role does the order of execution of code segments play in achieving the desired functionality?

The order of execution of code segments in PHP is crucial for achieving the desired functionality because it determines when certain actions or operations are performed. If code segments are not executed in the correct order, it can lead to unexpected results or errors in the program. To ensure the correct order of execution, it is important to carefully structure the code and consider dependencies between different segments.

// Example of ensuring correct order of execution in PHP

// Code segment 1
$variable1 = 5;

// Code segment 2
$variable2 = $variable1 * 2;

// Code segment 3
echo $variable2;
