RegExp help

Note: $code is a single line of code that the previous segment of this
method has located.

I have this...

preg_match('/\bnew wBug\s*\(\s*(.+)\s*\);/i', $code, $arrMatches);
$results = $arrMatches[1];


it will find this...

new wBug ( $myvar ); // <-- this is what $code contains

and it will give me...

$myvar

Which is exactly what I want, for this instance, but if I have this...

new wBug ( $myvar, true ); // <-- this is what $code contains,
this time

I get this...

$myvar, true

I'd like to only get....

$myvar

Actually, I'd like to get each parameter in its own array element of
'$arrMatches'

My RegExp is limited on this one.

Can someone throw me a bone?

Thx

walter

wait, wait, wait. so you are opening what apparently is a php script and
parsing it?

try:

/new\s+wBug\s?[^(]*\(\s*([^,)]*)[,)]/i

First of all, are you sure regex is the way to go here? It looks awfully=
=

like a parser should be involved...

And while it's perfectly doable to create a regex for it, why not apply =
=

KISS and:

if(preg_match('/\bnew wBug\s*\(\s*(.+)\s*\);/i', $code, $arrMatches)){
$results =3D $explode(',',arrMatches);
array_walk($results,'trim');
}
It's a LOT easier to maintain then a regex...

how about this, no regexp, just simple sub strings

$string = 'new wBug ( $myvar , true )';
$firstpos = strpos($string,"(");
$lastpos = strrpos($string,")");
$str=substr($string,$firstpos+1,$lastpos-$firstpos-1);
if ( strstr($str,",") )
{
$var=explode(",",$str);
echo $var[0];
}
else
{
echo "$str\n";
}

usually a great way to go. however when parsing, there's no good way to get
around the literal difference v. abstract differences between 'new wBug (
$myVar' or 'new wbug($myVar' or any other variation. all are the same
when seen by php, but not by strpos - which looks for literal string
occurances. regex can more easily account for any variation of 'new wBug'
and return exactly what the op is looking for.
