ereg problem

[Richard Grove - ®ed Eye Media]

Can any of you kind people tell me what I'm doing wrong?

An example:
$code="<gateway>FooBar</gateway>";
$var="gateway";

I am trying to get the FooBar information from the $code by passing $var and
$code to a regular expression:
$value=eregi("<$var>[a-zA-Z0-9 ]<$var>", $code, $value);

I am trying to make $value contain FooBar.

No worries, I've sorted this now:

if(eregi("<$var>(.*)</$var>", $code, $out)) {
$value = $out[1];
}
$value=eregi_replace("<$var>","",$value);
$value=eregi_replace("</$var>","",$value);

Why not try a more generic solution e.g.:

$code="<gateway>FooBar</gateway>";
preg_match("/<([^>]+)>([^<]+)<.*/",$code,$match);

where $match is an array containing:
0=> FooBar (full patern match)
1=> gateway (first parenthesis)
2=> FooBar (second parenthesis)

now you could do:

$$match[1] = $match2;

wich would resolve in $gateway="FooBar"
