While( ) statment exceptions?

do only first time threw?

[Sarah Atkinson]

Ihave a while statement and only the first time it cycles I want it to do something. All other times I simply want it to skip it. I though aboult something like
$x=0;
while($n=9){
if ($x==0)
//do whatever;
$x=1;
//do all the rest;
}

but is their an easer way?

if it needs to loop and do something only when a certain value is true, then that is the way to do it

I dont get this though
$x=1;

[Sarah Atkinson]

let me add the brakets in (i don't include them when i have only one lined ifs

$x=0; //sets a boolean style verriable

while($n=9){
if ($x==0){
//do whatever;
}
$x=1; //basicly says that the while statment has executed at least one time
//do all the rest;
}

could also do something like ++$x; and keep a tally of how many times the while statment has cycled.

but I want a statment to happen the first time and only the first time and other statments to happen as normal.

You could take the first statement out of the while loop ... thus simplifying the code ...

// do whatever
while($condition){
//do all the rest;
}

won't that work?
