sounds like ltrim() is what you're looking for:

ltrim — Strip whitespace (or other characters) from the beginning of a string!

echo $result_string = ltrim($string);

Not sure whether you just want to strip blank lines, or remove everything after the \n from the first instance of a word... went with the former so hopefully this is what you're after:

$string = "String first line

string second line";


$replaced = preg_replace('/[\r\n]+/', PHP_EOL, $string);
echo $replaced;

Returns:

String first line 
string second line

You can also use it like this:

if(startsWith($resultContent, '\n')) {  // true:  if string starts with '\n'
    str_replace("\n",null,$resultContent);
}

Just explode and take the first result
Do not forget to do some test : if !is_array() .....

$x = explode("\n", $resultContent);
$resultContent = $x[0];
