echo doesn't return them, it prints them. Minor but important difference. Programs return a number that you don't see but can check for to see if the program succeeded or failed... 0=success, anything else means error.

Shell expansion (often called globbing) happens before the program is run, the same way it substitutes variables. This means you can drop a * almost anywhere you like and it will become a list of files -- not just into shell commands but also shell builtins, lists, arrays, and operators... To make * not expand you have to put it in quotes like "*" or '*'

So when you do "echo *", the * becomes a list of files before echo is run at all, and echo doesn't have to do anything special to do what you'd expect it to. Do an echo "*" though and the shell will not substitute for *, and echo just prints it unchanged.

echo `echo ` doesn't echoes anything. And it's logic. But echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo" (too much echoing :P):o (2 Replies)

GET_MAGIC_QUOTES_GPC(3) 						 1						   GET_MAGIC_QUOTES_GPC(3)

get_magic_quotes_gpc - Gets the current configuration setting of magic_quotes_gpc

SYNOPSIS
bool get_magic_quotes_gpc (void ) DESCRIPTION
Returns the current configuration setting of magic_quotes_gpc Keep in mind that attempting to set magic_quotes_gpc at runtime will not work. For more information about magic_quotes, see this security section. RETURN VALUES
Returns 0 if magic_quotes_gpc is off, 1 otherwise. Or always returns FALSE as of PHP 5.4.0. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.4.0 | | | | | | | Always returns FALSE because the magic quotes | | | feature was removed from PHP. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 get_magic_quotes_gpc(3) example <?php // If magic quotes are enabled echo $_POST['lastname']; // O'reilly echo addslashes($_POST['lastname']); // O\'reilly // Usage across all PHP versions if (get_magic_quotes_gpc()) { $lastname = stripslashes($_POST['lastname']); } else { $lastname = $_POST['lastname']; } // If using MySQL $lastname = mysql_real_escape_string($lastname); echo $lastname; // O'reilly $sql = "INSERT INTO lastnames (lastname) VALUES ('$lastname')"; ?> NOTES
Note If the directive magic_quotes_sybase is ON it will completely override magic_quotes_gpc. So even when get_magic_quotes_gpc(3) returns TRUE neither double quotes, backslashes or NUL's will be escaped. Only single quotes will be escaped. In this case they'll look like: '' SEE ALSO
addslashes(3), stripslashes(3), get_magic_quotes_runtime(3), ini_get(3). PHP Documentation Group GET_MAGIC_QUOTES_GPC(3)
