Re: [PHP] Re: parsing a string
I tried the print_r on $res. The preg_match does the first set fine.
So I get:
Campus
Bob (Williams)
the second one starts
-
Address123 Main St
-
CityOxford
and so on

use print_r on the $res to check for the results (I'm not 100% sure if
they'll come out in $res[2], $res[3], $res[4], etc. or in $res[4][0],
$res[4][1], etc.

Do you Yahoo!?

Re: [PHP] Re: parsing a string
I knew I shouldnt have abreviated the string.
here is the string sorry I kinda flubbed on the last string
"LocationCampus~\\n-\nNameBob
Williams~\\n-\nAddress123 Main St~\\n-\n..."
the ... is a very long list.
how does this change the preg_match

[PHP] Re: parsing a string
Not sure what you want exactly, but here's a way using regexps to
retrieve the strings seperatly:
$string = 'CampusBob (Williams)~\toms more
crap)~\blah blah blah)~\';
preg_match('#([^|]*)[|]+([^|]*)~[\]+([^\]*)~[\]+([^\]*)~[\]+#Ui',
$string, $res);
$campus = $res[1];
$bob = $res[2];
$crap = $res[3];
$blah = $res[4];
?>
Now, if you wanted the positions... then something like this would work:
$string = 'CampusBob (Williams)~\toms more
crap)~\blah blah blah)~\';
preg_match('#([^|]*)[|]+([^|]*)~[\]+([^\]*)~[\]+([^\]*)~[\]+#Ui',
$string, $res);
$campus = strpos($string, $res[1]);
$bob = strpos($string, $res[2]);
$crap = strpos($string, $res[3]);
$blah = strpos($string, $res[4]);
?>

$x = explode('~', $string);

Make sure that for each \ in the string, you use \\ (that's why there
are 10 in my example. If you have 5 \ you need 5 \\)

Great!. I love it when I see stuff like this written by someone
who knows regex better than I. The ability to insert the
pieces that are recognized/extracted via \1, \2 is pretty cool.
Thanks.

Hey John,
something like this might work:

echo $string;
