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
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]).

this helps alot:

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
Thank you !

Let me know.
I optimized it a li
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)
12 matches
