Preg_Match...

[phpSensei]

I really Suck with delimeters and Regular expressions so can someone help me?

 

I have a date of birth field which needs to be in this format dd/mm/yyyy...

 

But I want the script to detect if the format is as followed "

 

Number Number / Number Number / Number Number Number Number/

 

So it contains no Strings, and I want to use some kind of explode to see if it has three sections and each seperated by "/"...

 

Anyone help?

A very basic regex pattern:

$dob = '02/01/1964';

echo '<b>DOB: </b>' . $dob . '<br />';


if(preg_match('|[0-9]{2}/[0-9]{2}/[0-9]{4}|', $dob))
{
    echo 'Date of birth is in the correct format';
}
else
{
    echo 'Date of birth is not in the correct format';
}

If you don't like regular expressions, explodes are normally a great alternative.

 

$dob = explode("/", $dob);

 

if(count($dob) != 3){

// wrong format

}else {

// right format

}

 

This doesn't check to make sure the parts are a set length. It would probably be better to cast the parts as int's and check the value that it would be to just make sure they contained two numbers - both because the two numbers could be out of range, and because it seems weird to require leading zeros.

Wow, they both work..

 

 

Thanks guys, I really think this forum is the greatest of all of them.
