Question

Lets say I have a string "My name is $name and my pet is $animal"

How to check if string has variables inside it? And if has, add to array like

$array = ("$name","animal");

Would it be some pregmatch? but then all $+sometextafterthesymbol needs to be extracted and $ with space after it left alone.
Any ideas?

You can use regular expressions for this. The following will match any dollar sign followed by 1 or more word characters (letters, numbers, or underscore):

preg_match_all('/\$(\w+)/', $string, $matches);

$matches:

Array
(
    [0] => Array
        (
            [0] => $name
            [1] => $animal
        )

    [1] => Array
        (
            [0] => name
            [1] => animal
        )

)

Remember that $string, if hardcoded, must be wrapped in single quotes (').
