[SOLVED] Another noob question :)

[shane18]

when you do

 

if($BLAH = $BLAH2)

 

... that makes $BLAH value = $BLAH2.... and if that makes $BLAH higher than 0(aka makes it true)... it makes the if statement true?

 

i been coding with unanwsered questions.. and now i been on here helpin with easy stuff and asking questions to improve my knowledge more

yea if you use a single equals sign it equates to true, but I'm not sure if that's what you're asking

if $BLAH = NULL, and $BLAH2 = 6...

 

 

if you do if($BLAH = $BLAH2)

 

that will be true because $BLAH now has the value of 6.. which makes the statement true right?

$a = $b will return what ever the value of $b is:

 

 

$b = true;

if($a = $b) //true

$b = 1;

if($a = $b) //true

$b = '1';

if($a = $b) //true

$b = false;

if($a = $b) //false

 

 

You get the point.

$b = 1;

if($a = $b) //true

$b = '1';

if($a = $b) //true

$b = false;

if($a = $b) //false

 

 

You get the point.

 

 

then from that point forward...

$BLAH = 0;

$BLAH2 = 6;

if($BLAH = $BLAH2)//Equals TURE

 

and then

 

echo $BLAH would display 6 right?

you're basically saving the contents of $blah2 into $blah, then using $blah to test for true/false.  so basically, as long as $blah2 doesn't contain 0, null, or false, it should be true.

thanks man for clearing that up
