preg_replace problem

I am running The following on a Windows 7 platform:
Setting Value

User Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

with the following code I get a deprecated warning:
$vr_str="";
foreach ($var_hsh as $key => $value )
{

$var_t="
";
$value=ereg_replace ($var_t , "", $value);

$vr_str=$vr_str.$key.$dlmtr.$value."
";
}

I change the sixth line to preg_replace

and I get the foloowing warning:
Warning: preg_replace() [function.preg-replace]: Empty regular expression in

I gather they are trying to replace a newline with nulls????

This is a Joomla component and they are not running the latest PHP version (I assume).

I am just getting back into PHP coding and this has me stumped.

It does look like it. If so, one might as well use str_replace:

$vr_str = "";
foreach ($var_hsh as $key => $value )
{
    $value = str_replace("\n", "", $value);

$vr_str .= $key . $dlmtr . $value . "\n";
}

When you do that are you also adding pattern delimiters to $var_t?

But yeah; as laserlight writes, [man]str_replace[/man] is by far the easier way to go with this, as is "\n" instead of "
";
