- Abiliy to parse specific command line arguments.
- Utilization of namespaces.
This program parses arguments from the command line. The program, testArgs.php, should exist directly in the src directory, while the ParseArgv.php class should be in src/Models/Utilities.
Running the program involves passing in a list of arguments on the command line (in any order), of a certain form, for example:
php testArgs.php -v --grades=good -T 5 -l val1,val2,val3 --names=Dominic,Mimi,Luke
The following types of arguments are accepted:
- A single dash followed by a letter (no space separating them) followed by either no argument or by a space and either a single argument or a comma-separated list of arguments that are either integers or strings.
-m 1,2,3 -Z bailey -f -a Erica,is,36,inches,tall
- A double dash followed by a string (one or more characters) followed by an equal sign followed by a comma separated string of arguments or just one argument with no comma.
--geek=eckroth,duncan,hans,sam --cool=plante --slick=sam,RYAN,Huddy,drew,john
Note that single and double-dash arguments can be interspersed, as shown in the initial example above.
The command line arguments are parsed into three groups: FLAGS, SINGLES, and DOUBLES.
FLAGS are single dash parameters with no arguments.
SINGLES are single-dash parameters with one or more comma-separated arguments,
DOUBLES are double-dash parameters with one or more comma-separated arguments.
The results are printed by category on one line, followed by all parameters and their arguments on separate lines, followed by the number of arguments in the line. For the first example, output would look something like:
FLAGS 'v'
SINGLES 'T' => '5' (1 argument) 'l' => [0] 'val1', [1] 'val2', [2] 'val3' (3 arguments)
DOUBLES 'grades' => 'good' (1 argument) 'names' => [0] 'Dominic', [1] 'Mimi', [2] 'Luke' (3 arguments)
