A basic question on php..

[Ezio]

Hey guys,

could someone explain to me the use of:

1. " === " e.g; ($i % 2 === 0 || $i % 5 === 0)

2. is there something like "$i+-" ?

[Ingolme]

If you know what == is, === is similar, but it also makes sure that the type of the two variables is the same:

$a = 1;$b = "1";if($a == $ { // This statement evaluates to true because $a and $b are both 1    echo "A and B are both 1";}if($a === $ {  // This statement evaluates to false because $a is a number and $b is a string    echo "A and B are both 1 and are both the same type";}

Thanks Ingolme.

 

But what about the 2nd one?

2. N0

[Ingolme]

What would $i+- do?

[Ezio]

nothing, that was a stupid question..

..as "Birbal" replied there is nothing like "$i+-".

[astralaaron]

theres $i++ and $i--

 

$i+- seems like it would just remain the same if it did exist :-)

[Ezio]

Yeah right.
