输入中的国际电话号码格式

Question

I have an input like this one:

<textarea name='phone_number' id='phone_number' cols='80' rows='1'><? echo $_POST['phone_number']; ?></textarea>

well, i made a function in PHP to validate the phone number( check that's not empty and no chars in it, just + and numbers)

and now, i want to format it inline in that input with some JQuery/JavaScript thing, but the format i'm thinking something International like if i have:

0016073222153 to be [phone]

0049329351525 to be [phone]

any ideas how can i do this? appreciate it ! thanks!

Answer 1

For the country code, this is not very complicated (I think), just a bit of grunt work.

You can get the list of country codes here. Then you fetch the first digit and determine from the calling code table if there's a next digit you should read; repeat until you have determined the country code.

For the rest of the numbers you could just do something like:

join('-', str_split($nr, 3));

This gives you groups of 3 digits, separated by a dash.
