If you're going to only accept 12-hour input, this is the right thing to do. 00:nn is not a valid 12-hour representation - only times from 1:nn to 12:nn are acceptable. If you were to accept 00:nn, you'd have to also accept 13:nn-23:nn as well, for consistancy. Granted, not specifying am or pm adds a layer of ambiguity, but maybe that's not relevant for this query. For example, maybe there's also a select field that has am and pm as options. As it appears that accepting only 12-hour input is part of the brief, Jim is IMHO doing the right thing.

OK - I don't yet understand how this works, but it seems to work for almost
all cases. The one erroneous result I get is from a value of 0040 (which I
convert to 00:40 before hitting the regexp). It comes thru as Ok. If you
have a fix for that I'd appreciate it - otherwise I'll have to devote some
book-time to mastering this string and come up with a fix myself.
Thanks again!!

Nope - that didn't work. Tested it against 1900, 1300 and 13:00 and all
came thru as OK.
Also - I don't understand at all the following:
FYI: ? is equal to {0,1}, and [1-9] to [123456789] (and therefore [1-2]
to [12]).
I know (?) that [1-9] validates any digit from 1 to 9 - I was already using
that.
And your point about [1-2] doesn't make sense to me since I need to validate
10:00 which [1-2] in my usage would cause 10:00 to fail.
And I don't know what ? means at all.
FWIW - I couldn't find much in the way of tutorials on the meanings of the
various chars in regexp's.

I can not correct your regexp. But I must tell you that trying to tweak a
regex for hours is surely **not productive**. If you got any type of text
processing dont always go for regular expression. This problem can be
solved just by simple string parsing.
Here I have done that for you.
function valid_time($time){
$m = (int) substr($time, -2);
$h = (int) substr($time, 0, -2);
return ($h=0 $h13 $m=0 $m60);
}
That won't work, it doesn't account for the possibility of a single digit
hour field.
I would do something like this:
?php
$times = array(
'100', # valid
'1100', # valid
'1300', # invalid
'01:00',# valid
'12:59',# valid
'00:01',# valid
'00:25pm', # invalid
'', # valid
'a00', # invalid
'00', # invalid
);
foreach ( $times AS $time )
echo {$time} is .(valid_date($time)?'valid':'invalid').\n;
function valid_date($time) {
if ( ( $c_time = preg_replace('|[^\d:]+|', '', $time) ) !== $time )
return false;
if ( ( $pos = strpos($c_time, ':') ) !== false ) {
list($hour, $minute) = explode(':', $c_time, 2);
} else {
$break = (strlen($c_time) - 2);
$hour = substr($c_time, 0, $break);
$minute = substr($c_time, $break, 2);
}
$hour = (int)$hour;
$minute = (int)$minute;
if ( strlen($c_time) = 2 )
return false;
if (
( $hour = 0 $hour = 12 )
( $minute = 0 $minute = 59 )

Thanks for the work you did, but I really wanted to try to solve this using
the more elegant way, which from my readings over the last year as a new
php developer, seemed to be the regexp methodology. I'm so close - it's
only the 1300,1400,etc. time values that are getting by my expression.
And thank you Shiplu also for your simple, but non-regexp, solution. Yes -
it works and I had something similar that was just missing one more check
when I decided to explore the regexp method.

How about this instead?

if ( ( $c_time = preg_replace('|[^\d\:]+|', '', $time) ) != $time )

preg_match('#^(?Phour\d{1,2}):?(?Pminute\d{2})$#', $time, $m);

Re: [PHP] regexp novice
Jim L. I did't actually consider that wide range of time values. Here
is an update. Still this can be written without help of regex. I must
add one more thing that a '00:01' is invalid in 12 hour format. OP
wants it to be 12-hour format.
function valid_time($time){
$m = substr($time, -2);
$h = (explode(':', substr($time, 0, -2)));
$h = $h[0];
return (is_numeric($h) is_numeric($m) $h0 $h13
$m=0 $m60);
}

Hi everyone,
I hope you're doing well (haven't written here for a long time :-)).
The question is as follows: I have a regexp that would do the
following. If the string begins with Re:, it will change the
beginning to Re[2]:; if it doesn't, then it would add Re: at the
beginning. But (attention, here it is!) if the string starts with
something like Re[4]:, it should replace it by Re[5]:.
Here's the code:
$start=mb_strtolower(mb_substr($f['Subject'], 0, 3));
if ($start==re:) {
$subject=preg_replace(/^re:(.+?)$/usi, re[2]:$1, $f['Subject']);
} elseif ($start==re[) {
// Here $1+1 doesn't work, it returns Re[4+1]:!
$subject=preg_replace(/^re\[(\d+)\]:(.+?)$/usi, re[$1+1]:$2,
$f['Subject']);
} else {
$subject=Re: .$f['Subject'];
}
I know there actually exists a way to do the numeral addition
(Re[5]:, not Re[4+1]:).
How do I manage to do this?
This looks like a job for the e modifier (see
http://php.net/manual/en/reference.pcre.pattern.modifiers.php, and example #4
at http://php.net/preg_replace). Something like:
$subject = preg_replace(/^re\[(\d+)\:](.+?)$/eusi, 're['.(\\1+1).']:\\2',
$f['Subject']);
Cheers!

Watch out for the missing '[1]'. This needs to become '[2]' and not '[1]'.
The callback seems to be the only way I could get the regex to work.

Already provided an example using that : http://news.php.net/php.general/308728
It was the 'e' modifier I couldn't get to work, though I suppose, as
the code is eval'd, I should have been able to do it.
The callback just seems a LOT easier.

Sorry - I missed the callback function in there. The loop threw me off
because I thought that was part of the solution rather than a test

Regular expressions do not support any mathematical operations. Instead, you
need to use preg_match() to extract the number inside the brackets,
increment it, and build a new string using simple concatenation (.).
elseif ($start==re[) {
if (preg_match('/^re\[(\d+)\](.*)/i', $f['Subject'], $matches) 0)
{
$f['Subject'] = 'Re[' . ($matches[1] + 1) . ']' . $matches[2];

I know there actually exists a way to do the numeral addition
(Re[5]:, not Re[4+1]:).
How do I manage to do this?
Thanks!
Can you adapt this ...
?php
$s_Text = 'Re: A dummy subject.';
foreach(range(1,10) as $i_Test)
{
echo $s_Text = preg_replace_callback
(
'`^Re(\[(\d++)\])?:`',
function($a_Match)
{
if (count($a_Match) == 1)
{
$i_Count = 2;
}
else
{
$i_Count = 1 + $a_Match[2];
}
return Re[$i_Count]:;
},
$s_Text
), PHP_EOL;
}
Outputs ...
Re[2]: A dummy subject.
Re[3]: A dummy subject.
Re[4]: A dummy subject.
Re[5]: A dummy subject.
Re[6]: A dummy subject.
Re[7]: A dummy subject.
Re[8]: A dummy subject.
Re[9]: A dummy subject.
Re[10]: A dummy subject.

RE: [PHP] regexp questions
Hi,
I'm trying to insert a serialized data into mysql, but I does
mysql_real_escape_string() before inserting it.
INSERT IGNORE INTO `table` (`value`) VALUES
('a:3:{s:12:F1;s:6:nombre;s:11:F2;s:5:F3;s:16:F4;s:10:F5;}');
it result in
INSERT IGNORE INTO `table` (`value`) VALUES
(\'a:3:{s:12:\F1\;s:6:\nombre\;s:11:\F2\;s:5:\F3\;s:16:\F4\;s:10:\F5\;}\');
and of course it's not a valid SQL sentence.
Why can't I escape an SQL value with ???
Regards.
I.Lopez.

It appears that you're performing the mysql_real_escape_string on the
entire query, and not the variables you're using in your query, hence
the single quotes that denote an SQL string being escaped.

[PHP] regexp questions
Hi, I've recently changed from php 5.1 to 5.3.2 and I'm havong problems with preg_match, because the same regular expressions used in php 5.1 are not matching anything in 5.3.2. There are any significant changes that I should know? I've been searching but I haven't found anything. Thanks.

Re: [PHP] Regexp and Arrays
On a quick glance I don't think you are doing the casting correctly. For
example, you have stuff like:
(string) $string;
and
(string) $key;
(int) $val;
and
(int) $length_value = $match[1];
and the casted value is not being saved anywhere.
I believe it should be something like $string = (string) $string; in order to
assign the casted value back to the variable. In the third example, you
probably meant $length_value = (int) $match[1];

Re: [PHP] Regexp and Arrays
I think part of the problem may lie in the use of variables in regular expressions. I am trying to use the perl-style preg_match(), but the regular expression values that it checks on each iteration of the foreach loop checks for a different value (hence, the use of a variable).

[PHP] Regexp to get paramname
Hi,
I have these lines to get parameters' name to $regs, but I always get the
first one twice.
What do I do wrong?
$sql = 'select * from hotsys where ALREND=:alrend and SYSKOD=:syskod';
eregi('(:[a-z,A-Z,0-9]+)', $sql, $regs);
Thanks,

RE: [PHP] RegExp
I'm not trying to pre-populate the text area.
I just want to get the input from the user and make sure he can
only insert chars that I allow. The only char I have a problem with
is the (Quote). If I enter a into the text area the regexp bellow
does not allow it in.
preg_match(/^[à-úA-Za-z0-9_():,@\/\.\s\- ]*$/i,$FieldValue) - Fails
preg_match(/^[à-úA-Za-z0-9_():,@\/\.\s\\- ]*$/i,$FieldValue) (This one gives
a php error cause the \\ closes the opening )
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s- ]*$/i',$FieldValue) - Fails
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s\- ]*$/i',$FieldValue) - Fails
preg_match('/^[א-תA-Za-z0-9_():,@\/\.\s\\- ]*$/i',$FieldValue) - Fails
So how can I allow a quote () to be a valid char?
thanks

Are you sure you are remembering to do http://php.net/htmlentities on the data
you send out for the TEXTAREA to pre-populate it?
Does PCRE need escaped inside the [] bit? I think not, but I suppose \\
instead of \ couldn't hurt.
You may also want to move the - to the end of [] character set and lose the \,
just to keep it simpler.

avoid sticking your regexps in double quotes strings - you just end up
giving yourself an escaping headache.
what is exactly is the goal of the 'limit' you are imposing - wouldn't something

You want to use preg_match_all, not preg_split:
$String = 'Medaillons, Listels, custom stuff, more things, entryway,
accents, showplace';
$MyRegEx = '/[^]+|[^\s,]+/';
preg_match_all($MyRegEx, $String, $Tokens);
echo 'pre';
var_dump($Tokens);
produces:
array(1) {
[0]=
array(7) {
[0]=
string(10) Medaillons
[1]=
string(7) Listels
[2]=
string(14) custom stuff
[3]=
string(13) more things
[4]=
string(8) entryway
[5]=
string(7) accents
[6]=
string(9) showplace

[PHP] Regexp matching in SQL
I am trying to simplify an SQL query that is pretty much like below: $sql = SELECT * FROM table WHERE keyword RLIKE '$expression1' OR keyword RLIKE '$expression2' ; The different terms '$expression1' and '$expression1' come from an array. Is there any way to within one regular expression to say either term1 or term 2? Something like this where the OR condition would be basically built into the regular expression: $sql = SELECT * FROM table WHERE keyword RLIKE '$expression'; // the $expression would have to signify either a or b.

Re: [PHP] Regexp matching in SQL
IN ( exp1, exp2) didn't seem to work for me. I've seen that used
before for including a subquery, but somehow it didn't like the comma
separated list.
I think this below is doing it for me.
$separated = implode(|, (explode( ,
(AddSlashes($_REQUEST['terms']);
if($_REQUEST['c'] == and){
$conditional = 'AND';
}else{
$conditional = 'OR';
}
$delim = WHERE Keyword REGEXP '$separated' $conditional
ItemDescription REGEXP '$separated';
I'm still curious about the IN() keyword and how it works.

[PHP] Regexp trouble
Hi list
I still fail to understand why regular expressions are causing me such a hard
time.
I used and tested my regexp in kregexpeditor (comes with Quanta [kdewebdev])
but when I put it in the php script it fails.
ereg('^([\w]{3,3})[\s]([\d]{2,2})[\s]([\d]{2,2})[:]([\d]{2,2})[:]([\d]{2,2})'
Does not match my query string.
Which is
Nov 22 06:51:36
Any ideas why? I mean Line start, followed by 3 word chars, followed by a
space, followed by 2 digits, followed by a space, followed by two digits,
folowed by a colon followed by 2 digits and followed by a colon, should match
that date?
With kind regards

Hi!
Why don't you use 'preg_match'? And why do you use all those character
classes?
This:
code
$subject = 'Nov 22 06:51:36';
$pattern = '/^(\w{3})\s(\d{2})\s(\d{2}):(\d{2}):(\d{2})/';
if (preg_match($pattern, $subject, $matches)) {
print_r($matches);
}
/code
nicely prints:
Array
(
[0] = Nov 22 06:51:36
[1] = Nov
[2] = 22
[3] = 06
[4] = 51
[5] = 36
)
Bye

Re: [PHP] Regexp trouble
Andy Pieters wrote: Err.. why NOT use character classes? What is easier [0-9] or \d or maybe [a-zA-Z] or [\w], ... ? Well, first of all the square brackets in [\w] aren't needed, \w already means 'any word character'. Secondly, [a-zA-Z] is not the same as \w: A word character is any letter or digit or the underscore character, that is, any character which can be part of a Perl word. The definition of letters and digits is controlled by PCRE's character tables, and may vary if locale-specific matching is taking place (see Locale support above). For example, in the fr (French) locale, some character codes greater than 128 are used for accented letters, and these are matched by \w. [http://www.php.net/manual/en/reference.pcre.pattern.syntax.php] Anyway I'm not really a great RegExp expert, a good starting point for understanding regexp and PHP is, as usual, the manual: http://www.php.net/manual/en/reference.pcre.pattern.syntax.php Bye! -- tradeOver | http://www.tradeover.net ...ready to become the King of the World? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

First of all thx :).
Just an idea... (Becouse im not that good at it).
Is it possible to create a while loop for the whole part?
Simply sad...
while .*? do { parse the contents of that tag in someway and change it? }
Becouse i think it is imposible with RegEx alone to make it so that it can
handle every attribute within a tag.

Hi!
I had a script for parsing text into html, similar to phpBB. Everything
has been working fine until now. Some of my 'pseudotags' like [b] are
still recognized (parsed into b) but some more advanced pattern
matching is not. I haven't changed the code, but the php-version on the
server has changed from default on debian-woody to php-4.3.10. I
haven't made the upgrade myself.
The users of the site reported the bug to me this week, but the users
aren't active so I don't really know when then bug was created. Because
I know it has worked before.
Does any of you have a clue or experience of this? Or has my code been
mysterious altered on the server?
An example of the expressions?

[PHP] Regexp help second
Hi!
Last help about regexp solve my problem, but I have another one.
I've made some regexp but it does not work always
Let say I have some strings
1) this is some domain.com test
2) domain.com
I can make this work either for first example of fo second, but not for
both. What I want is replace of domain.com to get
this is dome domain.com domain com test so replace should be
\1 \2 \3
so for second example I did /((.+)\.{1}(.+))/
How can I extend this to work in both.
regards
Uros

Re: [PHP] Regexp help second
You could maybe cheat and add an X at the beginning and end of the string
before your Regex, then you will have:
X\1 \2 \3X
and you can strip off the initial X from \1 and the trailing X from \3
There's probably some fancy Regexp way to do it though.

Can you explain in a little more detail what you're trying to replace
domain.com with? I'm having trouble understanding your intentions. A
regular expression like: /([\w-]+)\.([\w-]+)/ should be able to grab
strings like domain.com in any type of string (I'm using the
preg_replace function).
