I need from regular expression for phone number that can match phones like this:

00354 554-54687 | +354 55445 6584 | +35845344 | +354 458621264

First of number must be '+' or '00' after that can be random count of numbers, spaces and '-'. Thank you

Cool.

Asking for it here is not going to get you anywhere though.

Show us what you have done yourself - and no I don't mean Google it and copy the first one you find.

And we will probably help you out.

This is not a difficult one as described.

Use ^ to represent the start of your string.
Use [] to encompass the required character sets at the start of your string; OR (|) comes in handy here
Use [] encompass the rest of the permitted character set
Use $ to represent the end of the string

Might I suggest the use of RegExr to assist you?

Tou could use is_int (or is_numeric).


Or use this:

$number = eregi("^([0-9])+([\.|,]([0-9])*)?$",$val);

(copypasta from php website, regex is hard to learn and I do not know how to edit it.)

eregi is deprecated for a start.

We also shouldn't be encouraging people to just copy and paste code - if he uses that he will have no idea how or why it works.

PHP Code:

preg_match("/[0-9|\+]{0,2}[0-9\- ]*/", $string, $matches);

Regex:

/[0-9|\+]{0,2}[0-9\- ]*/

Explanation:

/ Start delimeter (can be most characters, but the character that is used can't appear in the string)

[0-9|\+] Match any number, or a + sign. 0, 1 or 2 times.

{0,2} Match the previous set between 0 and 2 times, in other words; 0,1 or 2 times.

[0-9\- ] Match any number, dash or space.

* Match the previous set 0 or more times, in other words, as many times as they appear.

/ End delimeter

Tested and working with the example numbers you gave.

EDIT: As moopet pointed out, this code will also match strings such as 9+1, so it's not safe to use in production, but can be used as a starting point

That will also match "9+1" or an empty string or a zillion other combinations. It's a good starting point, though.

Oh crap, didn't think of checking things that it shouldn't match. Whoops, I'll see if I can improve on that one.

That's really cool. I've been meaning to learn RegEx anyway, and that will come in handy.

Thanks to all

I try to do it myself and it work.

This is my code

/^[\+|\(|\)|\d|\- ]*$/;
