[PHP] changing random numbers to a running numbers

Hey guys :)

I

while($i < 5)
{
$i = 1;
$i = $i++;
echo $i;
}
This will add +1 to the I var. it will echo 1 2 3 4 5 then stop... This is what I think your saying you need $i to +1 to have like 1: this 2: this 3: this so on so forth?

i know how to use $i++ but i have no idea how to use it in that special case.

Each time preg_replace is executed $i should raise by one. How can i tell preg_replace to raise $i by one each time it finds "area x" ?

while($str = preg_replace("!(area(.)[0-9]*)!","area $i",$text);)
{
$i = $i++;
}
I think that'd work?

had almost the same idea, but those won

how about spliting the text into lines and the use preg_replace or ereg_replace
cause if $text is whole text then it replace all text, but if you would have a loop that would
convert line by line...

PHP Code:

---


$lines = explode("\n", $text);

foreach($lines as $var) {
/* 
   you code wich would increment the $i
   and do rest whatever you would need
   also i'm not sure how the files were encdoded so try with \n and if it won't work
   try with \r
*/
}

take care.

[B]DanseMacabre very nice :)
But it gives me just the first line back. 0o
Any clue ? but i think we

eh it gives you only one line cause you are not appending the text into the variable named $str
it shall be

PHP Code:

---

foreach($lines as $var) {
$i = $i++;
$str .= preg_replace("!(area(.)[0-9]*)!","area $i",$var);
/* no look for the coma up there it's very important cause it will append each line
    into variable not overwrite it
*/
}
echo $str;

now please note the coma symbol before equation symbol, as the coma is very important so you would get all your records not just first or last one.

almost :) didn
