语句中的print函数始终返回true

Question

I have a question that really confuses me. If I write a print function in the statement is always return true. For example:

if (print('x') === 'y')
        echo 'true';

Now I know that is not how the things works and I should not write it, but I saw this question in another forum.

I checked it out and read that print always return 1, which mean it actually 1 === 'y' and still this should not echo true.

Any idea why is true?

Answer 1

Write your print() in () so that first print function executed then condition will be matched

<?php

if ((print('x')) === 'y')
        echo 'true';
