Newbie question, probably stupidly simple .. sorry !!
|
|
| Ha .. What ??!!?? 2004-12-10, 8:56 pm |
| Hi all, I have recently completed a php course (beginner I hasten to add)
and one of the unfinished projects was to create a bingo card. I have made a
working version of part of it (creates five random numbers from 90, and
orders them into columns based on their number) but when i try to run this
as a function, I get 'Warning: array_rand(): First argument has to be an
array in blah/blah.php on line 15'. Any help would be gratefully recieved,
thanks, Scruffy.
code follows >>>>>
<?php
srand ((float) microtime() * 10000000);
for($i=0;$i<=90;$i++){
global $numbers1;
$numbers1[]=$i;
global $numbers2;
$numbers2[]=$i;
global $numbers3;
$numbers3[]=$i;
}
function drawtable(){
unset($numbers1[0]);
for ($i=0;$i<5;$i++)
{
$name=array_rand($numbers1); <<<<<<<<<<<<<<<<<<<<line 15
$name2[]=$numbers1[$name];
if ($name<10) {for ($j=0;$j<10;$j++){unset($numbers1[$j]);}}else
if ($name>=10 && $name <=79){
for ($loop=10;$loop<=70;$loop+=10)
{
for($loop2=0;$loop2<=9;$loop2++)
{
if(($loop+$loop2)==$name){for
($j=$loop;$j< =($loop+9);$j++){unset($numbers1[$j]);}}
}
}
}else
{for ($j=80;$j<=90;$j++){unset($numbers1[$j]);}}
}
sort($name2);
for($loop=10;$loop<=90;$loop+=10)
{
print "<td>";
for ($i=0;$i<5;$i++)
{
$check=$name2[$i];
if ($check==90&&$loop==90) {print $check;}else
if($check<($loop)&&$check>=($loop-10)){print $check;}else{print
" ";}
}
print "</td>";
}
//foreach($name2 as $key=>$value){
//print $key." -key, $value -value - name2<br>\n";
//}
}

| Array $numbers1 is defined outside of "drawtable" function. If you want
to use this "global" variable value, then you'll have to put "global
$numbers1" into this function, or move also the variable initialization
into the function or pass the variable as the function parameter.
If you post your code, then make it a bit more readable.
Compare the one you sent with the one below (no changes in syntax made).

| I did as you said and put the global in the function, and all is well ine
the world again !!!
If you dont mind, can you explain the other ways around that you described
(ie move also the variable initialization
into the function or pass the variable as the function parameter) as Im
afraid you lost me a bit with these.
Many thanks again, Scruffy.
