I know I've seen something about this (I can't remember whether yea or nay),
but I can't remember where I found it as at the time I was looking for
something else... and now that I'm looking for it I can't find it again.
Anyways, what I've done is store variable names that end up being passed as
part of various query strings in some variables similar to -
$var_id = "id";
$var_name = "name";
In the file that receives the information I'd like to know if there's a
faster way of finding out the value of the passed variables in the query
string than a function that explodes the query string & returns the value of
the requested variable. i.e. -
function getID($variable)
{
// explode 'var=x' from query string
$id = explode( "&", $_SERVER["QUERY_STRING"] );
// search to find correct 'var=x' from query string
for( $i=0; $i<count($id); $i++ )
{
// if $tag is found, extract value & assign to $value[]
if( $r = eregi( $variable."=([0-9])*", $id[$i], $regs ) )
{
$value[] = $regs[1];
}
}
return $value;
}
