String Manipulation 

1. Changing Case

<?

$full_name = 'nicholas cage';

$full_name = ucwords($full_name);

echo $full_name;

// Use strtolower and strtoupper functions too

?>

2. Trimming White Space

<?

trim(" Test "); // Remove white space from both sides of a string

ltrim(" Test "); // Remove white space from left side of a string

rtrim(" Test "); // Remove white space from right side of a string

?>

3. Shuffle characters

<?

$full_name = 'nicholas cage';

$full_name = str_shuffle($full_name);

echo $full_name;

?>

4. Finding String Positions with strpos

<?

$full_name = "nicholas";
$letter_position = strpos($full_name,"h");
echo $letter_position;

?>

5. Splitting a line of text

<?

$full_name = "Jaydra,Joe,Elizabeth,Abby,Vilma,Laura";
$names = explode(",",$full_name);  // Returns an array by breaking string with "," sign
echo $names[0];

?>
