What are the potential pitfalls of using loose comparisons (==) in PHP?

Using loose comparisons (==) in PHP can lead to unexpected results due to PHP's type juggling. It can result in values being converted to the same type before comparison, which may not always be what you intend. To avoid this, it is recommended to use strict comparisons (===) which not only compare the values but also check if the types are the same. 

// Using strict comparison (===) to compare values and types
if ($var1 === $var2) {
    // Perform actions if $var1 is identical to $var2 in both value and type
}
