$ Ftext = file_get_contents ($ filename );

Is this correct:

$ Xml = "books. xml ";
$ F = fopen ('books. XML', 'r ');
While ($ data = fread ($ f, 4096) {$ xml. = $ data ;}
Fclose ($ f );

$ Xmla = preg_replace ('/ ', 'Lil', $ xml );

$ Xmla = preg_replace (' ','/Lil', $ xmla );



Echo "$ xmla ";

?>

$ Xml = implode ("", file ('books. XML '));

$ Xml = str_replace (array (' ',' '), Array (' ',' '), $ Xml); // Set Replace , Set Replace

Thank you, but it seems that some textures are missing. However, the result is not a new xml format.

The following code is as follows:
$ Xml = implode ("", file ('books. XML '));
$ Data = str_replace (array (' ',' '), Array (' ',' '), $ Xml );
// Set Replace , Set Replace
Echo $ data;
?>
However, the running result is:
