Question

I have a variable called $name and it contains something like this:

$name = 'FName_LName_DataX_Number_www.website.com';

I want to put all the data before the Number in an array withouth the underscores and the Number value too.

Something like this:

$array[0] = 'Fname Lname DataX';
$array[1] = 'Number';

$name examples:

$name = 'Roberto_Carlos_01_www.website.com';
$name = 'TV_Show_Name_785_www.website.com';

Your problem is special to use regular expressions. But at any time that someone gives that kind of solution another someone say regular expressions are evil!. So let’s play a little:

$index  = 0;
$array  = array();
$array0 = array();
$array1 = array();

$name = 'FName_LName_DataX_002_www.website.com';

$aux = explode('_', $name);

if (is_array($aux))
{
    foreach ($aux as $key => $value)
    {
        if (is_numeric($value))
        {
            $index = $key;
            break;
        }
    }

    foreach ($aux as $key => $value)
    {
        if ($key >= $index)
        {
            $array1[] = $value;
            break;
        } else
        {
            $array0[] = $value;
        }
    }

    $array[0] = implode(' ', $array0);
    $array[1] = implode(' ', $array1);
}

$name = 'TV_Show_Name_785_www.website.com';
result: 
array (
  0 => 'TV Show Name',
  1 => '785',
)

$name = 'FName_LName_DataX_002_www.website.com';
result: 
array (
  0 => 'FName LName DataX',
  1 => '002',
)

$name = 'Roberto_Carlos_01_www.website.com';
result: 
array (
  0 => 'Roberto Carlos',
  1 => '01',
)
