Why does this code echo Yes. even though variables are not equal!
$a = '0e462097431906509019562988736854';
$b = '0e830400451993494058024219903391';
if( $a == $b ) echo 'Yes.';
else echo 'No!';

In String, the == operator is used to comparing the reference of the given strings, depending on if they are referring to the same objects. When you compare two strings using == operator, it will return true if the string variables are pointing toward the same java object. Otherwise, it will return false .
Both equals() method and the == operator are used to compare two objects in Java. == is an operator and equals() is method. But == operator compares reference or memory location of objects in a heap, whether they point to the same location or not.
Algorithm. Define a string and take the string as input form the user. Two loops will be used to find the duplicate characters. Outer loop will be used to select a character and then initialize variable count by 1 its inside the outer loop so that the count is updated to 1 for every new character.
Both will treated as numbers, and PHP had limitations in number storage before. So check that.
Try to use '==='. it will check the type also, so those will not convert to numbers.

You want strcmp, not the equality operator.
