Created page with "= Using = === Description === Executes the expressions then runs the code within the statements and finally automatically runs unset() on each expression in the expressions lis..."

New page

= Using =

=== Description ===

Executes the expressions then runs the code within the statements and finally automatically runs unset() on each expression in the expressions list (Basically cleaning up after you).

<pre>
using( <expressions> )
{
statements
...
}
</pre>

=== Parameters ===

==== expressions ====

A list of expressions to execute separated by ,

=== Remarks ===

None.

=== Example ===

Example on a simple string:

<syntaxhighlight lang="sputnik">
my $cat = "yyy"; // String exists
using( $cat ) // using will use the string
{
println("str is: $cat"); // prints the string just fine
}
println("Final: $cat"); // nothing... the string no longer exists...
</syntaxhighlight>

Example of using it with a class that will be deleted after the using block ends:

<syntaxhighlight lang="sputnik">
using( $newString = new CString("meow") )
{
println("Hello world!: " . $newString);
}
// Immediately after the using block finishes the class gets unset() and its __Destruct will be run.
</syntaxhighlight>

You can also stack them example:

<syntaxhighlight lang="sputnik">
my $cat = "yyy";
using( $cat, $newString = new CString("meow"), $coolstring = new CString("moo") )
{
// the $cat and both class variables get unset once this block ends
}
</syntaxhighlight>
