PHP String Triming from left and right

We can remove blank space from left side of any string by using ltrim function.
$text= " This is my text";
echo $text;
$text=ltrim($text);
echo $text;
Same way we can remove blank space from right side of any string by using rtrim function.
$text= " This is my text";
echo $text;
$text=rtrim($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;
