What is the difference between => and >=?

Question

read the above

Answer 1

$a = 5;
$b = 4;

if ($a >= $b){
echo '$a is GREATER THAN OR EQUAL TO $b';
}else {
echo '$a is LESS THAN $b';
}

In this case $a is greater than $b. This >= means GREATER OR EQUAL TO, and the opposite means <= LESS THAN OR EQUAL TO. You've got to pay attention to the operands being compared. In my example it checks to see if $a is greater or equal to the operand $b on the right, and it is so it will be true echoing:

$a is GREATER THAN OR EQUAL TO $b

Answer 2

=> is used for associative arrays,
>= is used for comparison
