You can make use of a simple regex. This will test for

  • any number of spaces
  • '58'
  • 3 digits
$tests = [
  ' 58123',
  '     58123',
  '58123',
  '158123',
  '15813',
  ' 15813',
];

foreach($tests as $test) {
    echo $test, ': ', preg_match('/\s*58(\d{3})/', $test) ? 'true' : 'false', PHP_EOL;
}

58123: true
     58123: true
58123: true
158123: true
15813: false
 15813: false
