PHP embedding functions inside strings?
How to do a simple shell command like:

Code:
echo "Today's date is `date +%D`"

with PHP? Basically I'm looking to embed PHP library functions calls inside of PHP strings in much the same manner as above. Thanks

PHP Code:
<?php
$date = date();
echo "Today's date is $date";
?>

Note the double quotes. PHP will evaluate the variable in strings with double quotes (not single quotes).

Using concatenation:
Code:
<? echo "Today's date is " . date("Y-m-d") . "\n"; ?>

The above (neurtrongscott's example) is how I would do it in practice....

I don't like the style of putting PHP $vars in inside strings surrounded by double quotes. It can get confusing and hard to debug in code.

What if you're reading in a large file using file_get_contents() and you want the variables in that file to be evaluated? This file would not contain PHP code.

Hmmmm.

If you are reading in a file with PHP code, and then evaluating that code, I'm not sure what you mean.

Normally, to include PHP code in a file, we use include() or include_once().

Can you paste the code and be more specific?
