[Resolved] Replacing text symbol with "dynamic" variables

[tho68]

Hello,
I would sincerly appreciate your help. I am trying to replace various instances in a text that contains a fixed symbol with a variable that increases in number. The help I got so far lead to following code:
<?
$oldstring="BLA% BLA% BLA% BLA% BLA%";
$newstring=preg_replace('#%#e','isset($i)?0:++$i',$oldstring);
echo $newstring;
?>
Actual result echo output:
BLA1 BLA0 BLA0 BLA0 BLA0

Desired result would be:
BLAV1 BLAV2 BLAV3 BLAV4 BLAV5

or even better:
BLA<input type="text" name="V1"> BLA<input type="text" name="V2"> etc.

Thanks a lot for your time!

<?
$oldstring="BLA% BLA% BLA% BLA% BLA%";
$num = 1;
for($i=1;$i<=5;$i++){
$newstring=preg_replace('#%#e','$num',$oldstring);
$num++;
echo $newstring;
}
?>

first of all, thanks a lot for your swift response! I tested the code, but unfortunately it produces the following result:
"BLA1 BLA1 BLA1 BLA1 BLA1BLA2 BLA2 BLA2 BLA2 BLA2BLA3 BLA3 BLA3 BLA3 BLA3BLA4 BLA4 BLA4 BLA4 BLA4BLA5 BLA5 BLA5 BLA5 BLA5 "

the minimum I would need is
BLAV1 BLAV2 BLAV3..

and ideally instead of V(ariable)+Number a replace with an html tag:
BLA<input type='text' name="V1'> BLA<input type='text" mane='V2'> etc..
Again, thanks for your help!

In theory, this should work:

<?
$oldstring="BLA% BLA% BLA% BLA% BLA%";
list($string1, $string2, $string3, $string4, $string5) = split('[# #e]', $oldstring);
function Loop(){ for($num=1; $num<=5; $num++){
$var = "<input type='text' name='V$num'>";
}
return $var;
}
preg_replace('#%#e', Loop($var), $string1);
preg_replace('#%#e', Loop($var), $string5);
preg_replace('#%#e', Loop($var), $string4);
preg_replace('#%#e', Loop($var), $string3);
preg_replace('#%#e', Loop($var), $string2);
$newstring = $string1.' '.$string2.' '.$string3.' '.$string4.' '.$string5;

echo $newstring; 
?>

Thanks for the code! It should work, the only problem being that when the text becomes large it would require a lot of code typing. I just received a really great suggestion from a German php forum. A user called "derHund" devised the following code that works perfectly:
<?
$oldstring='BLA% BLA% BLA% BLA% BLA%';
$oldstring.=' dummy';

$old = explode ('% ', $oldstring);

for ($i=0; $i<sizeof($old)-1; $i++)

echo $old[$i].'<input type="text" name="V'.$i.'" /><br />';

?>

Thanks again for your effort!
