Answer 1

• (=) is a Assignment operator while (==) is a Equal to operator.
• (=) is used for assigning the values from right to left while (==) is used for showing equality between values.

Example:

$test = 1;
if($test=2){
echo "Hello";
}

if($test==2){
echo "world";
}
//The result is Hello because = is assigning the value to $test and the second condition is false because it check the equality of $test to the value 2.

I hope this will help.
