What potential issues could arise when using IF statements in PHP?

One potential issue when using IF statements in PHP is forgetting to use double equals (==) for comparison instead of a single equals sign (=), which is used for assignment. This mistake can lead to unintended behavior in the code. To avoid this issue, always double-check the comparison operators in your IF statements. 

// Incorrect usage of single equals sign (=) for comparison
$number = 5;
if($number = 5) {
    echo "Number is 5";
}

// Corrected usage of double equals sign (==) for comparison
$number = 5;
if($number == 5) {
    echo "Number is 5";
}
