another strange include

[Guest askjames01]

include("lang/".$mg2->defaultlang);

ok, let me first try to explain it
is this include fetch the value from the variable defaultlang? right?
and put the inheritance into Class Object ('$mg2')? right?

and defaultlang variable can be found inside a class and
under a function? right?

please correct me if i'm wrong?

thanks.

*bump*

so what is the period all about in the front of $?
i checked the directory /root/lang/ and it has only a file namely english.php
is this line of code call the file english.php, because i'm so confused.

if you read the code --> include("lang/".$mg2->defaultlang); it does not indicate a filename
so maybe i assume that it is indicating the english.php which is the only file that residing
from the directory.

then if that is the case then what will happen if there are more than one files?
using the said code?

ok here are the english.php codes:

?>
[/code]

so what do you think my explaination above? is it all wrong or some how right?

[kenrbnsn]

This code line: [code]<?php include("lang/".$mg2->defaultlang); ?>[/code]

Has this meaning (and this meaning only)

Include the file that has the name that is equal to the string created by appending the string in "$mg2->defaultlang" onto "lang/".

The period in PHP is the concatenation operator. See the manual section on [a href=\"http://us2.php.net/manual/en/language.operators.string.php\" target=\"_blank\"]string operators[/a].

If you want to see what file is being included, put this line
[code]<?php echo 'lang/' . $mg2->defaultlang . '<br>'; ?>[/code]
before the include.
