What is the correct syntax for comparison in PHP if statements?
When comparing values in PHP if statements, the correct syntax is to use double equals sign (==) for comparison and triple equals sign (===) for strict comparison. Double equals sign will only compare the values of the variables, while triple equals sign will also compare the data types of the variables. Using the correct syntax ensures that the comparison is done accurately and avoids unexpected results.
// Correct syntax for comparison in PHP if statements
$var1 = 10;
$var2 = "10";
// Using double equals sign for comparison
if ($var1 == $var2) {
echo "Values are equal.";
}
// Using triple equals sign for strict comparison
if ($var1 === $var2) {
echo "Values and data types are equal.";
}
