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) && $h>0 && $h<13 &&
$m>=0 && $m<60);
}

How about this instead?

         '00:01',        # valid
         '00:25pm',      # invalid
         '0000',         # 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;

   preg_match('#^(?P<hour>\d{1,2}):?(?P<minute>\d{2})$#', $time, $m);

   if (
       $m &&
       ( 0 <= (int) $m['hour']   && 12 >= (int) $m['hour'] ) &&
       ( 0 <= (int) $m['minute'] && 59 >= (int) $m['minute'] )
      ) {
     return TRUE;
   }

   return false;

}

Let me know.

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.

Re: regexp novice

Jim Lucas — 2012-05-18T02:49:02

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
         '0000',         # 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;

this helps alot:

http://www.gskinner.com/RegExr/

you can paste your pattern (needle) in  the top input, and hover over each 
char to see what it means in grep land.
Paste your haystack in the big box (input), under that, to see where all 
your needle will be found.

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:


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.

Re: regexp novice

Yared Hufkens — 2012-05-17T20:58:37

Try this:
/(0?[1-9]|[12][0-9]):?[0-5][0-9]/

FYI: ? is equal to {0,1}, and [1-9] to [123456789] (and therefore [1-2]
to [12]).

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 && $h<13 && $m>=0 && $m<60);
}

Re: regexp novice

Jim Giner — 2012-05-17T20:43:46

OOPS
FORGOT to mention that I modify the string to add a colon if it is entered 
without one, so my regexp
always expects a ":" to be in the middle.  So in actuality - my regexp is 
'passing' a value of 13:00 as legitimate, when it should not be.

Jim Giner — 2012-05-17T20:37:12

ok - finally had to come up with my own regexp - and am failing.

Trying to validate an input of a time value in the format hh:mm, wherein 
I'll accept anything like the following:
hmm
hhmm
h:mm
hh:mm

in a 12 hour format.  My problem is my test is ok'ing an input of 1300.

Here is my test:

 if (0 == preg_match("/([0][1-9]|[1][0-2]|[1-9]):[0-5][0-9]/",$t))
    return true;
else
    return false;

Can someone help me correct my regexp?

Re: Bug in DOMDocument schemaValidate() function?

Voß, Marko — 2012-05-14T14:49:20

Hello,

I am sorry, but everything is ok here. I am performing an unmarshalling and marshalling unit test for every resource and 
the problem was, that after unmarshalling to the object, the marshalling of the object did not create the version 
element. I did not notice this in the first place.

So the validation error occured after the step of testing the marshalling and not before testing the unmarshalling.

Thank you anyways!

Best regards,
Marko

If you're 100% sure this XML is valid, then this is a bug. You should
report it at bugs.php.net, but it is most likely this bug is in
libXML, and needs to be fixed there.

Bug in DOMDocument schemaValidate() function?

Voß, Marko — 2012-05-14T11:39:13

Hello,

I am validating user DOM against schema files using the following piece of code:

$valid = < at >$doc->schemaValidate($xsdFile);

where $doc is of type DOMDocument and $xsdFile is the file location of the XSD file.

Everything worked fine until the following validation occured:

A validation of a XML against the SRW/U schema (http://www.loc.gov/standards/sru/sru1-1archive/xml-files/srw-types.xsd) 
failed.

Here is the XML:

one final gotcha; if you want to backup the git repositories, you have
to use xcopy /s /h source destination. it needs that /h to copy .git
directories that are hidden by default.

Hi all

As PHP-GTK has "moved" to the PECL, I suppose several part of this 
documentation are not relevent anymore: 
http://gtk.php.net/manual/en/tutorials.installation.linux.php

Would you know a place where I could find some way to work with it?
