ereg_replace

[chosun27]

I've looked through a bunch of tutorials and invariably the examples they use are much harder than what I'm trying to do. But none that I've looked through (including the documentation at php.net) clearly show how to do what I want to do. I am changing links from something like this:

table=intro&id=3 //where id can be a one or two-digit number

to this:

intro3.htm

I know that most programmers use matching for much more complex examples like url and zip code validation, but I haven't seen anything that does exactly this. Please help. Any links to tutorials that provide this kind of example are also much appreciated. I haven't found any that made sense.

Use ereg_replace instead:

$theVal = ereg_replace("&id=", "", ereg_replace("table=", "", $theVal));

that should do it! Or checkout this article: http://www.devarticles.com/art/1/106

<?

$table = trim($POST['table']);
$id=trim($POST['id']);

//to create a link

echo "<a href=\"./$table$id.htm\">click here</a>

//to create a redirect

$url="www.mysite.com/".$table.$id.".htm"

header("location:$url);

//hope i got the syntax right there

?>

Thanks for the suggestions,

Actually, these links are part of a page already constructed and inside a database, so the form handling won't work exactly. The first suggestion is close, it drops down to intro6, but it does not append the .htm. That is where I get stuck. How do I grab that whole tag ( <a href = "page.php?table=intro&id=6">) or whatever (each page has at least a dozen different ones) and then drop what I don't want and add the .htm while part of an entire page of HTML?

Is that clearer? Again, I am trying to go from <a href = "page.php?table=intro&id=6"> to <a href="intro6.htm"> .

thanks again for the help,

All done,

I'm quite surprised that I solved this before all you gurus, but I'm glad it is done. Here is my solution for those interested in doing something similar.

	$html = ereg_replace("page.php\?table=","", $html);
	$html = ereg_replace("id=([0-9]{1,2})", "\\0.htm", $html);
	$html = ereg_replace("&id=","", $html);

I dropped the page and table like Mytch suggested, but I didn't drop the id= part until I ran a replace on that because it was necessary for identification. The page id sitting by itself is just a number and you can't search on that. But once I matched that and figured out the syntax to tell it that there would be one or two numbers following it, then I could attach the .htm. And from there, the last part to drop wsa the &id= bit.
