$ftext = file_get_contents($filename);
preg_replace('String regular expression to be replaced', 'Replacement content',$ftext);

Is it correct for me to write this:

$xml = "books.xml";
$f = fopen( 'books.xml', 'r' );
while( $data = fread( $f, 4096 ) ) { $xml .= $data; }
fclose( $f );

$xmla=preg_replace( '/', 'lee', $xml );

$xmla=preg_replace( '', '/lee', $xmla );



echo "$xmla";

?>

The following is the code according to the code above:
$xml = implode("",file('books.xml'));
$data=str_replace( array('',''), array('',''), $xml );
// Replace with and with
echo $data;
?>
But the running result is:
