What potential issues can arise when using if and else statements in PHP?

One potential issue when using if and else statements in PHP is forgetting to include an else block, which can result in unexpected behavior if the condition is not met. To solve this, always ensure that there is an else block to handle the alternative scenario. 

// Example of using if and else statements with a complete else block
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is not greater than 5";
}
