You appear to be a bot. Output may be restricted

Description

Obtain a value for a command line parameter

If the required parameter key is numeric then we take the positional parameter else we take value of an NVP pair. This is a simple hack that's not as advanced as WP-CLI, which allows --no- prefixes to set parameters to false Here we're really only interested in getting url=

Usage

$string = oik_batch_query_value_from_argv( $key, $default );

Parameters

$key

( string ) optional default: url – Not expected to be prefixed with —

$default

( string ) optional default: localhost – Default value if not found

Returns

string value of the parameter
