Why is it important to use var_dump() instead of echo for debugging in PHP?

When debugging in PHP, it is important to use var_dump() instead of echo because var_dump() provides detailed information about a variable, including its type and value, making it easier to identify issues such as unexpected data types or values. Echo simply outputs the value of a variable as a string, which can be misleading and not provide enough information for debugging purposes. 

// Incorrect way of debugging using echo
$variable = "Hello";
echo $variable; // Outputs: Hello

// Correct way of debugging using var_dump
$variable = "Hello";
var_dump($variable); // Outputs: string(5) "Hello"
