Quick PHP Question, how to use a "goto" function

[WarDemon666]

I know in the BASIC language I could use a GOTO function to go back to a specific part of the script, is there a way i could do the same with PHP?

Thanks

goto = the most evil part of programing

do not use goto no matter what you are doing

How would i go about going back to the first part of the script again so it redoes everything again then?

i really need some help

thanks to all who reply

use functions

 

[Czar]

and for or while loops if you need them

 

[WarDemon666]

Please explain!

Could you give me an example or two?

Thanks

Don't you know, goto's are the Devil! Don't EVER use them!

Then could someone tell me how i could repeat a part of a PHP script several times, without having the script too large

Thanks

Create a function:

function dosomething() {
<insert here the part of the script you want repeated several times>
}

the script:
<?php
$i = 0;
while ($i == 0) {
dosomething; //this might be dosomething(), I haven't fiddled with PHP much as of late.
}
?>

This'll create an endless loop. So you might want to add another variable after $i = 0; put $d =0; Then after while($i == 0) { throw in $d = $d+1;. After the dosomething; statement add if ($d == 30) { exit; } replace 30 with the amount of times you want dosomething ran. Of course, there are also for loops and other methods of this. Which is faster I do not know, but this should work fine. If you need more help I recommend www.php.net's online manual. That is where I learned to write a forum system (much like the one I'm typing this on! ). You can also reply to this thread and if I see it I'll reply. Good luck to ya.

This is what i put in:

<?php
function test() {
echo "test"; }
$i = 0;
$d = 0;
while ($i == 0) {
$d = $d+1
test();
if ($d == $num) { exit; }
}
?>

I get a parse error on line 4, i have no clue why, can someone help me out please?
Thanks

Try something like this:
function test(){
echo "Test ";
}
$i = 1;
while ($i <= 10):

test();
print $i;
$i++;
if ($i <= 10){
echo ", ";
}
endwhile;
