How can the use of comparison operators like "==" and "===" impact the conversion of variables to strings in PHP?

When using comparison operators like "==" and "===", it's important to be aware of how PHP handles the comparison of different variable types. The "==" operator performs type juggling, which can lead to unexpected results when comparing variables of different types. On the other hand, the "===" operator performs a strict comparison that not only compares the values of the variables but also their types. To avoid issues with variable type conversion when comparing variables, it's recommended to use the "===" operator for strict comparisons. 

// Example of using the "===" operator for strict comparison
$var1 = 5;
$var2 = "5";

if ($var1 === $var2) {
    echo "Strict comparison: Equal";
} else {
    echo "Strict comparison: Not equal";
}
