Php – Remove the first 1 and space before a phone number?

I did searches and figured this would be an easy find. Though I haven’t found anything related to exactly what I need and similar questions are from people from overseas that have different phone formats with plus signs. A lot of my phone number entries start with a 1 and a space. I did a simple str_replace then I realized if a number has a 1 in the middle followed by a space, then that would mess it up

$string = trim($string);

$string = str_replace('1 ', '', $string);

That works for phone numbers beginning with

1 800-555-1111

1 222-555-1111

But in the case the phone number is

1 222 551 1111

Then that 551 and space would mess things up. How can it be rewitten so that only the first 1 and the following space is removed and the rest is untouched? Thanks.

EDIT

I forgot to mention that the entries do not always start with a 1 and a space. Sometimes they may be

888-555-1111

888 555 1111

1 888 555 1111

    To remove the first 1 and space

    substr($string,2)(without using the trim() method) or substr($string,1)(if you used the trim() method first) will work but are you sure that your number will always start with a 1 and whitespace?

    Do you have any checks or conditions added to make sure that the user input will always start with a 1 and followed by a space?

    If you are sure about that, then the substring solution removes those first two and then returns the rest of the string.

    You can use regex to achieve this:-

    $phone_number = '1 800-555-1111'
echo preg_replace('/^ds+/', '', $phone_number);
// Will echo 800-555-1111

$phone_number = '1 800 555 1111'
echo preg_replace('/^ds+/', '', $phone_number);
// Will echo 800 555 1111

    if sometimes the number could be 888-555-1111 -, use if :

    $str = "1 978 981 543";
$str_check = substr($str, 0, 2);
$need = "1 ";

if($str_check == $need) {
  echo substr($str, 2);
} else {
  echo $str;
}
