[PHP] Regex help please
I'm normally OK with regex, especially if I fiddle with it long enough,
however I have fiddled with this one so long that I'm either totally
missing it or it's something simple. Does it have anything to do with
the backref, or the fact that the value of the backref has a $? I have:
$out = '
{$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}';
And I want to capture the first {$tag}, everything in between and the
last {$/tag}. I have tried several things and here is my current regex
that looks like it should work, but doesn't:
preg_match_all('|{\$([^}]+)}(.+)({/\1})|Us', $out, $matches);
Gives:
Array
(
[0] = Array
(
)
[1] = Array
(
)
[2] = Array
(
)
[3] = Array
(
)
)

Shawn,
First thing I see--your first capture group doesn't include the $, and
so your final capture group will always fail given your current $out
(because it's looking for {/sites} instead of {/$sites}). Also, your
{} are outside of your capture group in \1, but inside in \3. Here's
what I came up with:
$out = '
{$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);
Produces this:
Array
(
[0] = Array
(
[0] = {$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}
)
[1] = Array
(
[0] = $sites
)
[2] = Array
(
[0] =
tr
td
{Site.id}
/td
/tr
)
[3] = Array
(
[0] = /$sites
)
)
Keep in mind, I had to view the page source in order to see the HTML
tags, but it showed me everything I expected to see.
HTH,

HTH,
Yes, thank you. I was fiddling before I got your post and I came up
with roughly the same.
preg_match_all('|{(\$[^}]+)}(.+){(/\1)}|Us', $out, $matches);

May have to go outside just a regex...
if ( preg_match ( /^\d{1}\.\d{2}$/, $number ) $number = 0
$number = 1 )

Re: [PHP] Regex help - PLease
Sorry I to should have added this this is what im going with so far preg_match(/\d100.*/); This will match a digit, followed by '100', followed by anything.

Hello Brent,

BC for example
BC 10064893
It's not a reg exp, but it will work:
if (is_numeric($val) == FALSE || strlen($val) 8 || substr($val, 0,
3) !== 100)
{
// $val doesn't match
}
Conversely:
if (is_numeric($val) == TRUE strlen($val) == 8 substr($val, 0,
3) == 100)
{
// $val does match
}
(Code not tested, but you get the idea I hope)

Unless you want to allow something like '10064893A' to match, use:
preg_match('/^100\d{5}$/', $test)

I have tried numerous variations, but my regex skills suck! I would appreciate anyone who can give me a pattern to use in preg_match_all() to match the following (I have the first part up to ANYTHING working): '|function ([\w\d\_]+)\((.*)\)ANYTHINGreturn (ANYTHING);|' So parsing a PHP file I hope to have 3 backreferences that return the function name, function args and return value (if present) of all functions.
