What are common mistakes when using if statements to check true or false values in PHP functions?

Common mistakes when using if statements to check true or false values in PHP functions include using assignment operators (=) instead of comparison operators (== or ===), not properly handling boolean values, and not considering type coercion. To solve this issue, always use comparison operators when checking for true or false values in if statements. Additionally, ensure that boolean values are explicitly checked using comparison operators to avoid unexpected behavior due to type coercion. 

// Incorrect way to check for true or false values
$value = true;
if ($value = true) {
    echo "Value is true";
} else {
    echo "Value is false";
}

// Correct way to check for true or false values
$value = true;
if ($value === true) {
    echo "Value is true";
} else {
    echo "Value is false";
}
