How does PHP handle boolean evaluation in conditional statements?

When evaluating boolean expressions in PHP conditional statements, it is important to remember that PHP considers certain values as false when evaluating to a boolean context, such as 0, false, an empty string, an empty array, or null. To ensure accurate boolean evaluation, it is recommended to use strict comparison operators (=== and !==) to explicitly check for true or false values. 

// Example of using strict comparison operators for boolean evaluation
$value = 0;

if ($value === true) {
    echo "Value is true";
} elseif ($value === false) {
    echo "Value is false";
} else {
    echo "Value is neither true nor false";
}
