Hiya, i need to format a string for php, like ("Your name is %s", Bob) would give "Your name is Bob".

Thanks

EDIT: this might help you inderstand, it's what i'm doing

PHP код:

<?php
include 'config.php';
echo exec(' killall -9 $svr ');
echo "<meta http-equiv=\"refresh\" content=\"1; url=index.html\" />\n";
?>

config.php makes $svr = samp03svr. And i know it works, as i've included and used it in other scripts.

sprintf

I think you can use also '.' ( echo exec(' killall -9 '.$svr ); )

I've tried sprintf, but i don't want to print it - i want to use it!

You don't need a format function.

Just use somethin like the following:

PHP код:


<?php
$string = "Your name is " . $nameString . ".";
?>

Would return (if nameString contained 'Bob'):

Код:

Your name is Bob.

EDIT: +rep if this helped, please. <3

In the vast majority of cases sprintf is overkill, and PHP offers alternative methods:

PHP allows for variables to be parsed inside strings (like in your example) with double quotes ("), but not single quotes like you are using.

Another method is to use the concatenation operator (full stop) like Farsek suggested.

(I also hope that $svr is sanitized if it is based on any kind of user input!)

I never actually knew i could use " in PHP, thanks for that!

It's not, $svr is definable in the config file

I know this has already been solved, but sprintf RETURNS the value, it doesn't print it:

http://www.php.net/manual/en/function.sprintf.php

"Returns a string produced according to the formatting string format."

or you can just use the . symbol tht concatenates the strings.
