i have string like this:
$mystr = "1,2,3";

and i want to use that string like the script (bold red text) below:
<?

$okvar = 1;
if ($okvar == (1||2||3)) {
echo "OK";
} else {
echo "ERROR";
}

?>

(1||2||3) is from $mystr
How to do that?

Well, not quite understand you, but:

$okvar = '(' . str_replace(',', '||', $mystr) . ')';

I kinda understand but at the same time i don't
Ill just assume

PHP Code:

<?

$mystr = "1,2,3";

$str=explode(",", $mystr);



$okvar = 1;

for($i=0; $i < count($str); $i++){

if($okvar == $str[$i]){

echo "OK";

} else {

echo "ERROR";

}

}



?>

no, not like that.

if $okvar must 1 or 2 or 3
+++++++++++++++++++

1 or 2 or 3 are from $mystr

PHP has a function called in_array: http://us4.php.net/manual/en/function.in-array.php

So you could do in_array(1,$mystr);
It returns boolean so you could do:

Code:

if(in_array(1,$mystr)) {

} else {

}

If you use the third parameter it wont work unless you do '1' because the strict parameter compares the type.

Let me know if that helps.

PHP Code:

$okvar = 1;

echo in_array($okvar, explode(',', '1,2,3')) ? 'OK' : 'ERROR'; 

This should work, if I understand your problem correctly.

YES, Almost, but it makes Loops.

outputs:
---------------------

OK
ERROR
ERROR

what if he has "1,2,3,55"

and $okvar was 5?

it would pass when it should fail

wheezy's method will work!

<?
$mystr = "1,2,3";
$okvar = 1;
if(in_array($okvar, $mystr)){
echo "works";
}else{
echo "error";
}
?>

Ahhh. You'll still need need to use an explode and put it into an array. Sorry about that.
