preg_replace() replacing all in loop

[sicapitan]

preg_match( "|<!-- InstanceBegin(.*)(-->)(.*)<!-- InstanceEnd -->|U",
$contents, $matches );

$my_template = $matches[0];
preg_match_all( "|<!-- InstanceBeginEditable(.*)(-->)(.*)<!--
InstanceEndEditable -->|U", $my_template, $editables );

$keys = array_keys( $editables[1] ); // from the editable region
names
foreach ($keys as $key)
{
$k = trim( ereg_replace( '["]', "", $key ) );

$on_mouse_over = "onMouseOver=hi_frame('$k');";
$on_mouse_out = "onMouseout=lo_frame('$k');";
$on_mouse_click =
"onClick=url_refresh('?option=com_oscar&task=edita rea&area=".urlencode($k)."');";
$new_contents = "<div id=$k $on_mouse_over $on_mouse_out
$on_mouse_click>". $editables[0][$k] ."</div>";
$pattern = "|<!-- InstanceBeginEditable(.*)(-->)(.*)<!--
InstanceEndEditable -->|U";
$placeholder = "<!--%ed".$k."-->";
$replaced_editables = preg_replace($pattern, $placeholder,
$my_template);

}

I want to loop through a string and replace the first instance of the
reg with <!--%ed0--> and the second with <!--%ed1--> etc untill the
loop has finished. But when I look at the output, the file is filled
with the last number - any ideas?

thanks

If you want to post code: make it easy to read: compact and snip the
irrelevant stuff.

Then your code is not complete, I don;'t see any line that outputs
anything. All T see is 1 preg_replace overwriting the same variable
again and again.
