How can placeholders be used in PHP for IF statements?

When using placeholders in PHP for IF statements, you can store the condition in a variable and then use that variable in the IF statement. This can make the code more readable and easier to maintain, especially if the condition is complex or needs to be reused multiple times. 

// Using a placeholder for an IF statement
$condition = ($a > $b);

if ($condition) {
    echo "a is greater than b";
} else {
    echo "b is greater than or equal to a";
}
