What are the potential pitfalls of using if statements in PHP for conditional logic, especially in relation to variable initialization?

When using if statements in PHP for conditional logic, especially in relation to variable initialization, one potential pitfall is the possibility of the variable not being initialized if the condition is not met. To solve this issue, it's important to ensure that the variable is initialized before the if statement to avoid any potential errors. 

// Potential pitfall: variable may not be initialized if condition is not met
if ($condition) {
    $variable = "initialized";
}

// Solution: initialize the variable before the if statement
$variable = ""; // initialize the variable
if ($condition) {
    $variable = "initialized";
}
