(PHP 5)php_strip_whitespace --

Return source with stripped comments and whitespace

Описание

string php_strip_whitespace (string filename)

- Returns the PHP source code in filename with

PHP comments and whitespace removed. This may be useful for determining the

amount of actual code in your scripts compared with the amount of comments.

This is similar to using php -w from the

commandline.

Замечание:

This function works as described as of PHP 5.0.1. Before this it would

only return an empty string. For more information on this bug and its

prior behavior, see bug report

#29606.

Возвращаемые значения

- The stripped source code will be returned on success, or an empty string

on failure.

Примеры

-

Пример 1. php_strip_whitespace() example

<?php

// PHP comment here

/*

* Another PHP comment

*/

echo php_strip_whitespace(__FILE__);

// Newlines are considered whitespace, and are removed too:

do_nothing();

?>

Результат выполнения данного примера:
<?php

echo php_strip_whitespace(__FILE__); do_nothing(); ?>

- Notice the PHP comments are gone, as are the whitespace and newline

after the first echo statement.
