[SOLVED] do while function... help

[shamuraq]

can't seem to get this to work...

$num = rand(1,9);
  do{
  $num1digit1 = rand(1,9);
  }while($num1digit1 = $num);
  
  echo $num1digit1;

Any sugestions?

i never used a do while in php... but i think this is the same

 

 

$num = rand(1,9);
$num1digit1 = rand(1,9);

while($num1digit1 != $num){ 
  $num1digit1 = rand(1,9); 
}

echo $num1digit1; 

 

not sure the point of it is though

[shamuraq]

the reason i use the loop is to prevent both the variables from having the same value...

ah ok then...

 

$num = rand(1,9);
$num1digit1 = rand(1,9);

while($num1digit1 == $num){
  $num1digit1 = rand(1,9);
}

echo $num1digit1; 

[shamuraq]

actually i'd just like to take this opportunity to clarify this

 

what is the difference between:

$num1digit1 == $num;

 

and

$num1digit1 = $num;

 

when i tried the second one, there are times it doesn't work...

[l0ve2hat3]

== is an operator... asking if something is equal to something

= is defining the variable

[ngreenwood6]

Just to clarify a little bit further:

 

== comparison operator (compare a value)

= assignment operator (assign a value)

 

The code that he gave you should work ALL the time

thanx y'all
