What potential pitfalls can arise from using assignment operations within conditional statements in PHP?

Using assignment operations within conditional statements in PHP can lead to unexpected behavior due to the order of operations. To avoid this, it is recommended to separate the assignment operation from the conditional statement. 

// Potential pitfall: using assignment within a conditional statement
if ($value = getValue()) {
    // This will always evaluate to true, even if getValue() returns a falsy value
}

// Solution: separate the assignment from the conditional statement
$value = getValue();
if ($value) {
    // Now the conditional statement will correctly evaluate the value returned by getValue()
}
