The backtick operator " ` " is used like an exec() or passthru() function.
But I know what you mean. For instance, try running this in a script:
$n = 1;
echo "The number is: $n++<br>";
echo "The number is: $n++<br>";
echo "The number is: $n++<br>";
PHP will not increment a variable inside of a string. However, now try this:
$n = 1;
echo "The number is: " . $n++ . "<br>";
echo "The number is: " . $n++ . "<br>";
echo "The number is: " . $n++ . "<br>";
But now try this:
$n = 1;
echo "The number is: " . ++$n . "<br>";
echo "The number is: " . ++$n . "<br>";
echo "The number is: " . ++$n . "<br>";
To do what you are wanting to do, just use the post-increment or
pre-increment operators, just like in Perl. Just be aware that PHP will not
do any mathematical functions on variables which are inside of a string.
