Use named arguments in code samples

[rodber]

Many code samples are taken "as-is" from the code, with the intention that the user will copy-paste the code to tryout. As PHP 8 adds named arguments I think that this:

$cache->withPut(key: $foo, varExportable: $bar);

Is easier to understand than:

$cache->withPut($key, $varExportable);

Code samples should be reviewed to use this language feature, it provides more clear examples.
