sprintf - repeating arguments

Question

I want to format a string with sprintf but repeating many times an argument. see..

$str = \"Str 1: %s - Str 2: %s - Str 2 again: %s\";


        

Answer 1

It's all in the documentation!

$str = 'Str 1: %1$s - Str 2: %2$s - Str 2 again: %2$s';
echo sprintf($str, "I'm string 1", "My name is string 2");

Note: Use single quotes for the format string otherwise you'll get PHP Notice: Undefined variable: s in /path/to/tofile:line

You can also escape the $ with a \ if you are using double quotes.
