I have a string with numbers and periods. For example '123456...'
I want to separate 123456 and ... and still get the number and the period in php.
I tried using preg_replace():

Code: Select all

$numbers = preg_replace('/[^0-9]/', '', '123456...');
$period = preg_replace('/./', '', '123456...);

With the code above I can extract the numbers but I can't extract the periods. Is there any other way to extract the periods?

It's because the dot (.) in regex is any character, while \. is literal dot.
Try the following code:

Code: Select all

$matches = null;
$input = '123456...';

preg_match('/(?<nums>\d+)(?<periods>\.+)/', $input, $matches);

$numbers = $matches['nums'];
$periods = $matches['periods'];

$nums_only = preg_replace('/[^\d]/', '', $input);
