ZEND MOCK TEST PREPARATION: comparison in php

php provides many ways to compare 2 variables. == operator doesn't check the type of the operands. it just compare the 2 operands with matching the type. === operator checks for the types of the operands also. If a string contains any numbers before having any characters in it like "1time", then === operator matches it with integer value "1". Any string without initial number are treated as 0 when converted to integer. let's see a zend mock question for php 5 certification.


Question: Which of the following comparisons will evaluate to true?

Answer:

1. 't' == t
2. 1 === "1time"
3. "top" == 0
4. "top" === 0
5. 1 == "1time"
