PHP Variable Stacking

[StormTheGates]

Any help is appreciated.

 

for($num=0; $num<=9; $num+=1){
  $exsettings='$settings['.$num.']';
  eval("\$exsettings = \"$exsettings\";");
  if($exsettings=='1'){
   $check$num='checked';
   
  }else{
   $check$num='';
  
  }
}

 

Basically I need the variables to stack, for instance $check$num would wind up to be increasing such as $check1 $check2 $check3.

 

How do I make it do this?

I think what you want is...

 

${$check$num} = 'value';

[StormTheGates]

Nope, dosnt work.

I am also having very similar problems, no idea what to do, any more thoughts anyone?

[hitman6003]

oops, forgot the concatenation operator...

 

${$check . $num} = 'value';

 

EDIT:

 

An example:

 

$check = 'value';

for ($i = 1; $i < 10; $i++) {
${$check . $i} = $i + 10;
}

echo $value1 . '<br />';
echo $value2 . '<br />';
echo $value3 . '<br />';
echo $value4 . '<br />';
echo $value5 . '<br />';
echo $value6 . '<br />';
echo $value7 . '<br />';
echo $value9 . '<br />';
echo $value9;

This is what I tried,

 

<?php
$userinfoget=mysql_query("SELECT `sms_credits`,`sms_phone`,`sms_settings` FROM `users` WHERE `username` = '$username'") or die(mysql_error());
$userinfo=mysql_fetch_assoc($userinfoget);

$settings=explode(",",$userinfo[sms_settings]);

$check='value';

for($num=0; $num<=9; $num++){
$exsettings='$settings['.$num.']';
eval("\$exsettings = \"$exsettings\";");
if($exsettings=='1'){
	${$check.$num}='checked';

}elseif($exsettings=='0'){
	${$check.$num}='';

}
}
echo"0 = $check0<br>1 = $check1<br>1 = $check2<br>3 = $check3<br>4 = $check4<br>5 = $check5<br>6 = $check6<br>7 = $check7<br>8 = $check8<br>9 = $check9<br>";
?>

 

It returned this...

 

0 =

1 =

1 =

3 =

4 =

5 =

6 =

7 =

8 =

9 =

 

Still doesnt work

 

Im sure theres a way of doing this though!

You need to use $GLOBALS Array

if($exsettings=='1'){
	$GLOBALS[$check.$num]='checked';

}elseif($exsettings=='0'){
	$GLOBALS[$check.$num]='';

}

Did you even bother trying hitman's method? It works! Its called variable variables and this is exactly its purpose.

 

You need to use $GLOBALS Array

 

What does it have to do with the $GLOBALS array?

What does it have to do with the $GLOBALS array?

He was talking that he need to make variables like

$check1, $check2, $check3, $check4, $check5, ...................

Thats why $GLOBALS Array will work here

if($exsettings=='1'){
	$GLOBALS['check'.$num]='checked';

}elseif($exsettings=='0'){
	$GLOBALS['check'.$num]='';

}

OOPS The previous one had a mistake.

[trq]

[code]The problem is this piece of code....

[code]
$exsettings='$settings['.$num.']';
eval("\$exsettings = \"$exsettings\";");

 

and the fact that $exsettings never equals 0 or one, hence the if() never runs. Try...

 

<?php

$settings = explode(",",$userinfo['sms_settings']);

$check='value';

for ($num=0; $num<=9; $num++) {
if ($settings[$num] == 1) {
	${$check.$num} = 'checked';
} elseif ($settings[$num] == 0){
	${$check.$num} = '';
}
}
echo"0 = $check0<br>1 = $check1<br>1 = $check2<br>3 = $check3<br>4 = $check4<br>5 = $check5<br>6 = $check6<br>7 = $check7<br>8 = $check8<br>9 = $check9<br>";
?>

 

Thats why $GLOBALS Array will work here

 

Sorry, but I still just don't see the point.[/code][/code]

There are thousand ways to do 1 thing you are doing it without using $GLOBALS array but it can be done using $GLOBALS Array also.

We could put all our variables in the $GLOBALS array if we wanted, but there wouldn' t be much point would there. My point is there is no point to your method.

Hey, Thanks very much for your help, the $GLOBALS method worked perfectly!

 

Did you even bother trying hitman's method? It works! Its called variable variables and this is exactly its purpose.

Yep, tried it, unless I was doing something wrong it didnt work in the way i needed it to, $GLOBALS did the trick

 

Also, it was stored in the database as "0,0,0,0,0,0,0,0,0,0", and was either set to 1 or 0

 

Thanks for your help once again
