Regular Expression

Copy linkTweet thisAlerts:
Jul 30.2013

HI

I am trying to write a regular expression that should match the following cases

  • 1. Should start with either + or 00

  • 2. After p#1, it should have numbers only and length between 11 – 16 chars

  • 3. Overall length including pt#1 and pt#2 should be minimum 12 chars and max 17 chars

    • Which means the following should be valid:
    +95215487511
    0041587695157

    My following expression does not work fine ?

    [code=php]
    <?php
    $reg =”/^[+|00]{1}[0-9]{12,16}$/”;
    $number = ‘065471852956’;
    $x = preg_match( $reg , $number);

    var_dump($x); // returns true
    [/code]

    Any help is appreciated

    Thanks

    @phantom007authorJul 30.2013 — One more rule

  • 4. if there is + then it cannot be followed by zero, and if there are 00 then it cannot have + at beginning.

    @NoEffinWayJul 30.2013 — I think this should do it:
    [CODE]/^+{1}[1-9]{11,16}$|^00{1}[1-9]{11,16}$/[/CODE]

    @iBeZiJul 30.2013 — This should work as an alternative to NoEffinWay's solution

    <i>
    </i>/^(?:+|00)[1-9][0-9]{10,15}$/

    NoEffinWay's solution does not seem to be working (for example +123456789012)

    iBeZi, ur regex works so far, will keep testing for more combinations and will update you.


    Thanks again

    cheers

    I am using the following regex:
    [CODE]/^(?:+|00)[1-9][0-9]{10,15}$/[/CODE]

    But it does not validate the following two numbers, any idea why?

    [CODE]005374152368
    +4865718575[/CODE]


    Thanks

    Thanks[/QUOTE]

    The numbers aren't long enough (+ or 00 followed by a number in the range of 1-9 followed by 10-15 of any number).

    The first number is 00 followed by a number (5), followed by only 9 other numbers, same with the second number except starting with +
    ×

    Success!
