ereg_replace help

zorzor

Hello

I need to replace "toto.php?link=00013010"
by "toto.php?link=000130101234"

my code is :
$test="1234";
$text=ereg_replace("((toto.php\?link=)([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])([0-9])([0-9]))", "\1$test", $text);

and the output is :
toto.php?link=0001301012341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234

Do you have some Idea ?
I need help for the syntax.

Thanks.

Zor.

uhhmmm...

it's just stupid to use ereg_replace here simplu do this:

$test = "1234";
$text .= $test;

$test contains n lines and i just want to modify the "toto.php?link=" in the middle of the $test.

And the number in 8 number is not the same in $test.

Need help...

<?
$replacement = "1234";
$text = ereg_replace("/(toto.php?link=[\d*])/e", "\1$replacement", $text);
?>

That should do it.

It should, but it doesn't.
"\1$replacement" is evaluated as "\11234", which is a non-existing backreference.

It's exactly my problem.

Is there a solution to this bad evaluation ?

Thanx.

Some tiny errors... this version if tested and working:

<?
$replacement = "1234";
$text = preg_replace("/(toto.php\?link\=[\d]*)/", "\0" . $replacement, $text);
?>

Note that it's no longer ereg_replace but preg_replace - don't know whether ereg_replace works as well.

The problem is that
"\0" . $replacement" is evaluated as "\01234"

and the output is :
...
com/toto.php?link=0001301012341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234
...

not on my box though...

I'm on PHP 4.0.6 Apache 1.3.20

and the output is http://mysite.com/toto.php?link=0001301012341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234123412341234

???

Thanx

Same configuration here, this is my script - I suggest to test this one as single file first:

<?
$text = "asdlfjbsdfkhsdfsfdtoto.php?link=00013010afgökjsbdgdfög";
$replacement = "1234";
$text = preg_replace("/(toto.php\?link\=[\d]*)/", "\0" . $replacement, $text);
echo $text;
?>

The resulting Output is:

asdlfjbsdfkhsdfsfdtoto.php?link=000130101234afgökjsbdgdfög

(without the "--").
As said, Apache-1.3.20, PHP 4.0.6, Linux 2.2.something.
Good Luck 🙂

Zor,
Just to confirm... you're using preg_replace and not ereg_replace, right?
I've run Dom's code (preg_replace) and it works here too... Win2K, Apache 1.3.1, PHP 4.06

Thanx for your help.
My $replacement is a number so I protect it whith "\0" and it's working.

<?
$replacement = 1234;
$text = preg_replace("/(toto.php\?link\=[\d]*)/", "\0\0" . $replacement, $text);
?>
