We can remove blank space from left side of any string by using ltrim function.

$text=rtrim($text);
echo $text; To remove extra blank space, line break, carriage return from both sides ( left and right ) of a string we can use trim function
$text= " This string has blank space at both sides ";
echo $text;
$text=trim($text);
echo $text;
