</ste:foreach>
 This code will loop through the array foo and return the counter $i, the key $k and the value $v of the current iteration.

+

+ There can also be an optional <ste:else> clause, that will be executed, if the input array was empty. +

+

+ Example:
+ 

<ste:foreach array="foo" value="v">
    <p>$v</p>
    <ste:else>
        Array \$foo is empty.
    </ste:else>
</ste:foreach>
+ This code will list all array elements or will display Array $foo is empty if the array $foo is empty. +

ste:infloop

Creates an infinitive loop. You can get out of the loop using the ste:break tag. Can be used to emulate other loop constructs like while loops.
