[PHP] Re: preg_match()

Good Afternoon.
This shouldn't be too complicated, but I can't come up with a solution for
the problem right now. It's about RegEx in PHP (5.2)
Is there a way to capture ALL sub elements of an expression like
preg_match('@a(?[0-9])*b@' ,a2345678b , $matches); ??
This would produce (below) whereas I'd like to get all the elements (2-8) as
an array entry each . ([1]=2, [2]=3 .)
AFAIK, you would need to know how many digits are there and use that
many capture groups (), because you only have one capture group which
will be overwritten each iteration. An alternative for your simple
example above would be to do:
preg_match('@a([0-9]+)b@' ,a2345678b , $matches);
--then--
print_r(str_split($matches[1]));
To do this multiple times in a large string you would need:
preg_match_all('@a([0-9]+)b@' ,a2345678b , $matches);
foreach($matches[1] as $match) {
print_r(str_split($match));
}

If you must know - it's data from a biology vertebrate museum. Thousands
of records may match a given query. Most of them look fairly easily
parsable and it does look like when a day is specified, it is always
first and year is always last.
The data is needed by me, so I'm planning on having the script die if it
comes across a date I don't have a regex to parse before it does
anything so I can add appropriate regex as necessary, but damn - you'd
think a vertebrate museum would have cleaned up their DB somewhat.
My first shot would be to see how far I get with strtotime(), or date_create().
The rest looks like a job for the Mechanical Turk (http://www.mturk.com/mturk).
For your specific query, you could do something like
(Jan|January|Feb|February|...) alternation, but that won't catch typos and
idiosyncrasies. You probably want to make it case-insensitive too.
I suspect you will end up with a bunch of records where the data cannot be
parsed sensibly - I would probably write the list of such records to an
exception file. Once you have a a system that generates a manageable number of
exceptions you can deal with those by hand.
As for your expectation of a museum: the reputation of dusty old rooms full of
stuff is not entirely un-earned, so I wouldn't expect their databases to be
spotless!

Hi Jared,
If the pattern delimiter character appears in the pattern it must be
escaped so that the regexp processor will correctly interpret it as a
pattern character and not as the end of the pattern.
This would produce a regexp error:
/ldap://*/
but this is OK:
/ldap:\/\/*/
Therefore if you choose another delimiter altogether you don't have
to escape the slashes:
#ldap://*#
Cleaner and more clear.
preg_match('|^ldap(s)?://[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$|', $this-server )
I also recommend using single quotes instead of double quotes here.
Single Quotes: Noted. Any reason why? I guess you might be a little out of
luck putting $vars into a regex without . concatenating.
Both PHP and regexp use the backslash as an escape. Inside double
quotes, PHP interprets \ as escape, while inside single quotes PHP
interprets \ as a simple backslash character.
When working with regexp in PHP you're dealing with two interpreters,
first PHP and then regexp. To support PHP's interpretation with
double quotes, you have to escape the escapes:
Single quotes: '/ldap:\/\/*/'
Double quotes: /ldap:\\/\\/*/
PHP interprets \\/ as \/
RegExp interprets \/ as /
There's also the additional minor argument that single-quoted strings
take less processing because PHP isn't scanning them for escaped
characters and variables to expand. On a practical level, though,
the difference is going to be measured in microseconds and is
unlikely to affect the perceptible speed of a typical PHP application.
So, for a pattern like this that contains slashes, it's best to use a
non-slash delimiter AND single quotes (unless, as you say, you need
to include PHP variables in the pattern):
$pattern = '#ldap://*#';
Personally I favor heredoc syntax for such situations because I don't
have to worry about the quotes:
$regexp = _
#ldap://*$var#
_;

Inside of a bracketed character class, the dot means a literal period
character and not a wildcard.
All non-alphanumeric characters other than \, -, ^ (at the start)
and the terminating ] are non-special in character classes

Also, why are you allowing for uppercase letters

I hadn't gotten far enough to strtolower(), but that's a good point, I
hadn't actually considered it yet.
Perhaps it has to do with the source of the string: can you guarantee
that the URIs passed to this routine conform to spec?
Another way to handle this would be to simply accept case-insensitive strings:
|^ldap(s)?://[a-z0-9-]+\.[a-z.]{2,5}$|i
Pattern Modifiers
http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php
i (PCRE_CASELESS)
If this modifier is set, letters in the pattern match both upper
and lower case letters.

Warning: preg_match_all(): unknown modifier '#' in file
Gracious, did you start a long thread. Several workable solutions are provided.
I'd like to offer some general advice, I learned from experience.
I never use / as the delimiter; there are too many chances for errors. I generally use %, unless my haystack can
possible contain it. It is easier to spot syntax errors, for example. Otherwise, I use a delimiter that cannot be in my
haystack and is not a regex reserved character. Rarely is there a delimiter that is both in the haystack and is a
reserved character; if so, I just use literal code \ as required.
I never use repeated special characters e.g., \s\s use *, + or {n,m} as
needed.
I rarely use dot all [e.g., .] it accepts everything and can make testing very difficult. Invariably, there is a
combination I never thought of to test. I use explicit statements for everything that can be in my haystack [e.g., \d,
\w, [a-z], [0-9], \s, \S, etc.]
I always use the Reg Coach for complicated patterns and build and test the
pattern one step at a time.

You should use the ^ and $ characters which signify the start and the
end of the string respectively.
For example:
$matched = preg_match('/^www\.test\.com$/', $string);

Your regex is matching EVERYTHING before and after the div. It's also
matching the maximum of content between the div tags. Here's a better one:
/(div.*?\/div/i
1) You don't need to escape the and .
2) The ? after .* makes it match a minimum of content between the div tags.
3) the /i matches case insensitive, meaning that DIV will be matched as well
Note that this won't work quite right on nested div tags.

you don't need the .*? in your regex (either * or ? multiplier) as preg_match searches
for any occurance (not from begin ^ or to end $).

What the below loop needs to do, is search each entry of the array

Thanks,
I weas reading on the php website under the preg_match functino and
people were saying that you had to excape the $ so that iw ould be
evaluated right. That's what got me confused.

you could consider configuring a prebuild html editor (just WYSIWYG)

Andy Crain [EMAIL PROTECTED] wrote in message

My apologies in advance if this too basic or there's a solution easily
found out there, but after lots of searching, I'm still lost.
I'm trying to build a regexp that would parse user-supplied text and
identify cases where HTML tags are left open or are not properly
matched-e.g., b tags without closing /b tags. This is for a sort of
message board type of application, and I'd like to allow users to use
some HTML, but just would like to check to ensure that no stray tags are
input that would screw up the rest of the page's display. I'm new to
regular expressions, and the one below is as far as I've gotten. If
anyone has any suggestions, they'd be very much appreciated.
Thanks,
Andy
$suspect_tags = b|i|u|strong|em|font|a|ol|ul|blockquote ;
$pattern = '/(' . $suspect_tags . '[^]*)(.*)(?!\/\1)/Ui';
if (preg_match($pattern,$_POST['entry'],$matches)) {
//do something to report the unclosed tags
} else {
echo 'Input looks fine. No unmatched tags.';

Hello,
Can I get the starting position of my string occurence when using any
regexps searching functions in PHP ?
for example:
$mem='this is a test';
preg_match('/test/', ...) should return me somehow: 10
Thanks
strpos might be useful

It sounds like you need an exact match; note that your regex is matching
against substrings, thus additional invalid characters are allowed to pass.
Anchor the pattern, so that it essentially says From beginning to end, the
only chars allowed are one or more digits, optionally followed by the
combination of a period then two more digits. (The ^ and $ special
chars are anchors.)
A regex special character loses it specialness when it's either escaped
with a backslash, or included within a square-bracketed character class;
you don't need to do both.
The {1} is implied; you don't need it.
if (preg_match(/^\d+(\.\d{2})?$/, $form_data[amount]))
{echo Validated!;}
else
{exit(That's not a dollar amount.);}
