Is this seen as a strength or a weakness of PHP.? In C(++), direct comparisons to true/false are discouraged. In other words, instead of this: bool x; if(x==true) ... if(x==false) ... itt's always considered better to do this: if(x) ... if(!x) ... But PHP seems to require a direct comparison with false in certain situations. Are there any cases where you need to do a direct comparison with true?
