Functions?

[Abu Hafs]

Hello,

I just signed up for this google group with the hope that i will get
some help out here. I was looking into a source code given to me in
the office but i was unable to understand this funcion declaration,
can any body please help me

function & query ($sQuery) {
global $default;
$aParams = array();
if (is_array($sQuery)) {
$aParams = $sQuery[1];
$sQuery = $sQuery[0];
}

What is the & symbol is about in this code.

Thanks

The '&' symbol normal refers to passing a value by 'reference' (not a
copy) and is normally used like so:

function query(&$sQuery)
{
...
}

I've never seen it in front of a function name before. You'll find alot
more help in the newsgroups 'alt.php' and 'alt.comp.lang.php'

If you put an ampersand before your function name, the function will
return a reference to a variable instead of the value.
