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
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.

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]).

FWIW - I couldn't find much in the way of tutorials on the meanings of the
various chars in regexp's.

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

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,
13 matches
