Difference between == and === in php

Two of the many comparison operators used by PHP are '==' (i.e. equal) and '===' (i.e. identical). The difference between the two is that '==' should be used to check if the values of the two operands are equal or not. On the other hand, '===' checks the values as well as the type of operands. Let me explain more using some examples: '==' (Equal): if("22" == 22) echo "YES"; else echo "NO";      The code above will print "YES". The reason is that the values of the operands are equal. Whereas when we run the example code below: '===' (Identical): if("22" === 22) echo "YES"; else echo "NO"; The result we get is "NO". The reason is that although values of both operands are same their types are different, "22" (with quotes) is a string while 22 (w/o quotes) is an integer. But if we change the code above to t...
