What are common methods in PHP to remove characters from a string starting from the first space?

To remove characters from a string starting from the first space in PHP, one common method is to use the `strpos()` function to find the position of the first space in the string and then use the `substr()` function to extract the substring starting from the character after the space. This allows us to effectively remove characters from the beginning of the string up to the first space.

$string = "This is a sample string";
$first_space_position = strpos($string, ' ');
if ($first_space_position !== false) {
    $result = substr($string, $first_space_position + 1);
    echo $result; // Output: is a sample string
}
