Stepping through Multidimension Array

[jedeye]

i have tried many different built in functions from the php manual to no avail...

 

i have a class with a function to return the values from a query in an array...when it returns it returns as a multidimensional array

 

function code:

function getModelSpecs() {

	$array_of_specs = array();
	$i = 0;		

	$result = pg_query($this->dbConnection,self::stringGetModelSpecsSQL);

	while( $rows = pg_fetch_row($result) ){

		$specs = new ModelSpecsDTO();
		$specs->spec_id = $rows[0];
		$specs->spec_name = $rows[1];
		$specs->spec_description = $rows[2];
		$specs->css_category_name = $rows[3];
		$specs->spec_index = $rows[4];
		$array_of_specs[$i] = $specs;
		$i++;

	}

	return $array_of_specs;
}

 

my return values from "var_dump"

array(4) { [0]=> object(ModelSpecsDTO)#2 (5) { ["spec_id"]=> string(1) "1" ["spec_name"]=> string(5) "Width" ["spec_description"]=> string(13) "Product Width" ["css_category_name"]=> NULL ["spec_index"]=> string(1) "0" } [1]=> object(ModelSpecsDTO)#3 (5) { ["spec_id"]=> string(1) "2" ["spec_name"]=> string(6) "Height" ["spec_description"]=> string(14) "Product Height" ["css_category_name"]=> NULL ["spec_index"]=> string(1) "1" } [2]=> object(ModelSpecsDTO)#4 (5) { ["spec_id"]=> string(1) "3" ["spec_name"]=> string(5) "Depth" ["spec_description"]=> string(13) "Product Depth" ["css_category_name"]=> NULL ["spec_index"]=> string(1) "2" } [3]=> object(ModelSpecsDTO)#5 (5) { ["spec_id"]=> string(2) "-1" ["spec_name"]=> string(4) "Misc" ["spec_description"]=> string(13) "LSI Misc Data" ["css_category_name"]=> NULL ["spec_index"]=> string(1) "3" } } 

 

The problem is...

 

All i want to is the spec_name value from each array, but having a hell of a time trying to figure out the algorithm to step through the array and pull only that value for each array.

Any help is greatly appreciated...

It makes it hard to analyze the array when you put it all in one line like that. Could you do a print_r() and post the results. Also, either get the output directly in the HTML source (which will have the line breaks) or put the output inside PRE tags so it will display with line-breaks in the output.

You'd loop through the specs array. Example

foreach($array_of_specs as $specs)
{
    echo $specs->spec_name . '<br />';
}

@mj> that was a print_r

 

@wild> OMG.. i feel real dumb, thank you. i was totally trying to over complicate it by trying to slice the array n such

I also tried that exact step... however, i put it outside a loop for testing, just to see if it would spit out what i needed...

$connectDAO = daoFactory::getModelSpecs();

$model_specs = $connectDAO->getModelSpecs();

$model_specs->spec_name;

 

thanks again..

sorry, you're right that was var_dump() sorry.. prior to everything i was using print_r()

When you use pring_r() or var_dump(), inclose them inside <pre> tags, to get the desired output.

 

echo '<pre>' . print_r($var,true) . '</pre>';

Good tip, thanks

Or just view the output in the HTML source code (i.e. right-click View Page Source).

That seems to soar over the heads of newbies!!!
