[Resolved] PHP 4: Class: How can I dynamically creating a multi-dimensional array?

[jtp51]

Question:

PHP4 Specific

How can I dynamically creating a multi-dimensional array from multiple Class method calls?

Summary:

I have the following method in a class that creates an array from the three methods passed into the method:

function add_arg($arg_name = null, $arg_value = null, $arg_length = null) {
		if(!(is_null($arg_name) || is_null($arg_value) || is_null($arg_length))){
			$i = ++$this->_count_add_arg;
			$numargs = func_num_args();
			$arg_list = func_get_args();
			$arg = array();	
			for($j=0; $j < $numargs; $j++){
					array_push($arg, $arg_list[$j]);
			}
		}
	}	

When I call the method three times:

$o->add_arg("ARG1", '@', 1);
$o->add_arg("ARG2", '1', 1);
$o->add_arg("ARG3", '41', 2);

I get the following result of three seperate arrays:

[FONT=courier new]
Array ( [0] => ARG1 [1] => @ [2] => 1 )
Array ( [0] => ARG2 [1] => 1 [2] => 1 )
Array ( [0] => ARG3 [1] => 41 [2] => 2 )
[/FONT]

What I need to do next is put all three arrays into one (1) multi-dimensional array; such as:

Array (
[0] => Array (
	[0] => ARG1
	[1] => @
	[2] => 1
	)
[1] => Array (
	[0] => ARG2
	[1] => 1
	[2] => 1
	)
[2] => Array (
	[0] => ARG3
	[1] => 41
	[2] => 2
	)
)

I have tried to create a seperate method named [FONT=courier new]setArgs[/FONT] that uses the PHP method: array_map() and calling that within the method [FONT=courier new]add_arg[/FONT] noted above.

That doesn't work because it will get called three times...

If I try:

$o->setArgs();

Of course, that calls the method once. However, how do I get the three seperate arrays; created in the method [FONT=courier new]add_arg[/FONT] called three times; into the one method?

Isn't there a scope issue?

Any direction or help is greatly appreciated.

Thank you for reading this post.

Solved my question.

I changed my method to:

function add_arg($arg_name = null, $arg_value = null, $arg_length = null) {
		if(!(is_null($arg_name) || is_null($arg_value) || is_null($arg_length))){
			$i = ++$this->_count_add_arg;
			$numargs = func_num_args();
			$arg_list = func_get_args();
			$arg = array();	
			for($j=0; $j < $numargs; $j++){
					array_push($arg, $arg_list[$j]);
			}

		$this->_bargs[] = $arg;
	}
}

The called a new method:

 
function setArgs(){
		$arg_count = count($this->_bargs);

	$this->_finalArg = array();

    for ($i=0;$i<$arg_count;$i++) {
        array_push($this->_finalArg, $this->_bargs[$i]);
    }

    print_r($this->_finalArg);
}

Therefore, I was able to set multiple arguments for my object with one method named [FONT=courier new]add_arg[/FONT] with the following :

$o = new commonClass();


$o->add_arg("ARG1", '@', 1);
$o->add_arg("ARG2", '1', 1);
$o->add_arg("ARG3", '41', 2);
$o->setArgs();

Then combine all my arguments into one multi-dimensional array by calling the method [FONT=courier new]setArgs[/FONT] once.

The result:

Array (
[0] => Array (
	[0] => ARG1
	[1] => @
	[2] => 1
	)
[1] => Array (
	[0] => ARG2
	[1] => 1
	[2] => 1
	)
[2] => Array (
	[0] => ARG3
	[1] => 41
	[2] => 2
	)
)

For me, this solved my problem, hope this helps someone else...
