What are the differences between comparison operators and bitwise operators in PHP?

Comparison operators in PHP are used to compare two values and determine if they are equal or not, while bitwise operators are used to perform operations on binary values at the bit level. Comparison operators include ==, ===, !=, !==, <, >, <=, >=, which compare values based on their actual content. Bitwise operators include &, |, ^, ~, <<, >>, which manipulate individual bits in binary numbers. 

// Comparison operators example
$a = 5;
$b = 10;

if ($a == $b) {
    echo &quot;Values are equal&quot;;
} else {
    echo &quot;Values are not equal&quot;;
}

// Bitwise operators example
$x = 5; // 101 in binary
$y = 3; // 011 in binary

$result = $x &amp; $y; // Bitwise AND operation
echo $result; // Output: 1
