Hi,
I was wondering why ls * | echo does not print the contents of the directory to the screen? The way I see it, ls * returns a whole lot of information, and then we pipe all this info to echo, so surely it should all come to our screen!
Is there a serious flaw in my understanding?

OUTPUT_ADD_REWRITE_VAR(3) 1 OUTPUT_ADD_REWRITE_VAR(3)output_add_rewrite_var - Add URL rewriter valuesSYNOPSIS
bool output_add_rewrite_var (string $name, string $value)
DESCRIPTION
This function adds another name/value pair to the URL rewrite mechanism. The name and value will be added to URLs (as GET parameter) and
forms (as hidden input fields) the same way as the session ID when transparent URL rewriting is enabled with session.use_trans_sid. Please
note that absolute URLs (http://example.com/..) aren't rewritten.
This function's behavior is controlled by the url_rewriter.tags php.ini parameter.
Note
Calling this function will implicitly start output buffering if it is not active already.
PARAMETERS
o $name
- The variable name.
o $value
- The variable value.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
output_add_rewrite_var(3) example
<?php
output_add_rewrite_var('var', 'value');
// some links
echo '<a href="file.php">link</a>
<a href="http://example.com">link2</a>';
// a form
echo '<form action="script.php" method="post">
<input type="text" name="var2" />
</form>';
print_r(ob_list_handlers());
?>
The above example will output:
<a href="file.php?var=value">link</a>
<a href="http://example.com">link2</a>
<form action="script.php" method="post">
<input type="hidden" name="var" value="value" />
<input type="text" name="var2" />
</form>
