PHP - How Can Find Some Of Words And Replace It ..

Hi
i wrote a find and replace code but my code replace last value of array and skip the first, second.... values in the array.
Please give me an idea because i stack with this code.

Regards


$KeyWord  = explode("\n", $RowGetWords['KEYWORDS']);
$Replace  = explode("\n", $RowGetWords['ReplaceTo']);

for($i=0; $i<count($KeyWord); $i++){
$pattern = $KeyWord[$i];
$replace = "<a href=\"" .$URL. "\" target=\"_blank\" >" .$Replace[$i]. "</a>";
$html = str_replace($pattern, $replace, $Row['MessageBody']);
}

Hello

I'm making a guestbook in PHP and I'm having trouble displaying the posts. The user fills a form and sends it, it goes into the database (mysql) and I can then fetch the data. So far so good.

I'm then going to use HTML to display the posts to the user. It's code looking like this:

Code: [Select]
<p>
<br /> ID: ---replaceid--- <br /><br />

Time: ---replacetime--- <br />
From: <a href="---replacehomepage---">---replacefrom---</a> <br />
Email: ---replacemail--- <br /> <br />

Comment: ---replacecomment--- <br /><hr>
</p>

I want to use str_replace in PHP to replace the values in HTML... like this:
Code: [Select]
$numquery = mysql_query("SELECT * FROM guestbook", $dbconnect);

$num = mysql_num_rows($numquery);
$i=1;
while ($i < $num) {

header('Content-type: text/html');
$html = file_get_contents("test.html");

$query = mysql_query("SELECT * FROM guestbook WHERE id='$i'", $dbconnect);
$rows = mysql_fetch_row($query);

echo str_replace('---replaceid---', nl2br($rows[0]), $html);
echo str_replace('---replacetime---', nl2br($rows[1]), $html);
echo str_replace('---replacefrom---', nl2br($rows[2]), $html);
echo str_replace('---replacemail---', nl2br($rows[3]), $html);
echo str_replace('---replacehomepage---', nl2br($rows[4]), $html);
echo str_replace('---replacecomment---', nl2br($rows[5]), $html);

$i++;
}


But this only replaces ---replaceid---, leaves the rest and outputs it. Then, only ---replacetime--- is replaced and so on.
I hope you understand. It means that 1 guestbook entry is displayed like 6, with only 1 string replaced at each one.

What do you think I should do?

Worth saying is that I'm not allowed to mix PHP-code with HTML-code

I have a long string of html, and what I want to do, if find all occurrences of:

/static (anything after)...

and replace with:

http://www.mydomain.com/static (anything after).

What is the best and fastest way to do this? Thanks.

I have this code reads the xml runs with no errors but will not input the data from the array in the <catparent>

The script

Code: [Select]
<?php
// isbn => pages
$page_numbers = array(
                     '1234' => 'hello parent', // insert data into catparent node
                     '5678' => 'hello parent', // insert data into catparent node
                );
$dom = new DOMDocument();
$dom->load('edtest1.xml');
$xpath = new DOMXPath($dom);
$items = $xpath->query('item');
foreach($items as $item)
{
    $catcode = $item->getElementsByTagName['catcode'];
$parent_code = $page_numbers[ $catcode[0] ];
$item->appendChild( $dom->createElement('catparent', $parent_code) );
}
$dom->save('edtest_stack.xml');
?>

My XML file looks like

Code: [Select]
<?xml version="1.0" encoding="UTF-8"?>

<items>

<item>
<catcode>1234</catcode>
<catdesc>Systems - System Bundles</catdesc>
</item>

<item>
<catcode>5678</catcode>
<catdesc>Hard Drives - SATA</catdesc>
</item>
</items>

Output XML looks like this as you can see it has created the <catparent> but will not insert the data from the array.

Code: [Select]
<?xml version="1.0" encoding="UTF-8"?>
<items>

<item>
<catcode>1234</catcode>
<catdesc>Systems - System Bundles</catdesc>
<catparent></catparent></item>

<item>
<catcode>5678</catcode>
<catdesc>Hard Drives - SATA</catdesc>
<catparent></catparent></item>
</items>

Any ideas pointers as to where I'm going wrong would be most helpful

I'm trying to increment a numerical value and after several hours of reading haven't come up with a solution.
this may be too much information but here it is;

I'm using this code to change the values in r5include.html

Code: [Select]
<?php $ident = $_POST['ident']; ?>
<?php
$ident2 = ($ident . 2);
$filename = 'r5include.html'; 
$string = file_get_contents($filename); 
$old = array("'images/up.jpg'","add.html' target='_blank'");
$new = array("'$ident/$ident2.jpg'","$ident.html' target='iframe2'");
$data = str_replace($old,$new,$string);
$handle = fopen($filename, "w+"); 
fwrite($handle,$data); 
fclose($handle); 
?>

but before I do that I'm copying the original to a temp file with this code:

Code: [Select]
<?php
$filename = 'r5include.html';
$string = file_get_contents($filename);
$tempfile = 'temp.html';
$handle = fopen($tempfile, "a"); 
fwrite($handle,$string); 
fclose($handle); 
?>
This is what goes to temp.html:

Code: [Select]
<img height=75 src='images/up.jpg'
hidefocus='true' usemap='#record51' />
<map name='record51'>
  <area shape='rect' coords='0,0,75,75'
href='add.html' target='_blank'>

I would like to increment the 2 instances of record51 to record52 and increment again each time the process is initiated.  And then  append it to r5include with this:

Code: [Select]
<?php
$myFile = "r5include.html";
$fh = fopen($myFile, 'a') or die("can't open file");
$filename = 'temp.html';
$string = file_get_contents($filename);
fwrite($fh,$string);
fclose($fh);
?>
So the question is is it possible? and if so how do I increment the record number? 

Thanks,
