PHP search & replace from index.php text boxes?

[gowner]

Hi everyone, this is my first post here and I'm a PHP newb, so excuse me if this is easy mode. I know a lot of HTML, etc. a bit of a "copy paste coder", but this is my first time really trying to make a script.

Essentially what I want is a script where on the index.php there's 2 boxes, 1 for the base content, and another for the variable that needs to be replaced within the content.

The variable will remain constant, we'll call it %VARIABLE%. However the text replacing the variable will change each time.

This base content is fairly long so hopefully that wouldn't be a problem. I've found a lot of str_replace() scripts online but I don't want to have to change the file each time.

Any help, or pointing me in the right direction would be much appreciated.

Thanks!

if you do not want to use str_replace then you should see if pattern matching regular expressions will help you. Here is an article that may help you -

So you will have many pages in the format www.domain.com/index.php?pagename=x ?
With the variable text different for each pagename (x), or whatever the parameter name is.
If so you could use a database table to store the different text values for each pagename, then reference the relevent text from the current url :

Table fields :
PAGENAME
TEXT

<?
foreach($_REQUEST as $name=>$value) {
${$name} = $value;
}

$result = mysql_query("SELECT TEXT FROM TABLE_PAGES WHERE PAGENAME='$pagename'");
$row = mysql_fetch_array($result);
$thistext = $row['TEXT'];

?>

// text box display

<input type="text" value="<?echo $thistext;?>" >
