help with a preg-replace routine

[phporcaffeine]

Let me explain -

I have an .rtf (rich text file) that is a "template" for a report format. My script gets values n' such from a DB then it open/reads the template file.

In the template file, there are " keywords " or " flags " that mark where the different values go, I then replace the individual flag with the appropriate value and fwrite the new file data to a seperate .rtf file.

It's very doable but I am running into a logic issue. I can't figure out how to replace a given "flag" with the appropriate value foreach() flag that preg_replace comes across.

Example:

[code]

$flags = array("flaga", "flagb", "flagc", "flagd");

$values = array("flaga" => $valuea, "flagb" => $valueb, "flagc" => $valuec, "flagd" => $valued);

$filedata = file("../my_template.rtf");

foreach ($filedata as $key +> $value) {

$hook = preg_replace($flags, (how do I get the appropriate value here for whatever preg_replace found?), $value);

$newdata .= $hook . "\n";

}

//$newdata should now contain the whol .rtf file with all the flag characters replaced with their appropriate values
var_dump($newdata);
[/code]


TIA

If you're not using any advanced rules for your replacements it would be better to use str_replace() instead of preg_replace(). In which case, you can use it like this:
[code]<?php
$search = array("old1","old2","old3");
$replace = array("new1","new2","new3");

$str = "old1 old2 old3";
echo str_replace($search,$replace,$str);
//The above will echo "new1 new2 new3"
?>[/code]

No, no advanced rules here -

I see what your doing though, as long as the value stays in the same stack position as the "flag" then it will always match...

I also know what you mean about preg_replace Vs. str_replace cause preg_ can be a stinker if your search string has anything but straight alpha in it.

-damint Jim, why didn't I think of that!
