string trim ( string $str [, string $charlist ] )

Example #1 Trimming array values with trim()

<?php
function trim_value(&$value) 
{ 
    $value = trim($value); 
}

$fruit = array('apple','banana ', ' cranberry ');
var_dump($fruit);

array_walk($fruit, 'trim_value');
var_dump($fruit);

?>

Example #2

<?php
$string = 'This string  has   no    whitespaces.';
echo ereg_replace( ' +', '', $string );
?>
Output: Thisstringhasnowhitespaces.
