PHP Echo specific column multi dimensional array

Question

I'm experimenting with a multidimensional array in PHP with strings as values. I want to echo all the values of one single column, instead of all values of all columns.

First i create the array!

$test = array
(
  array("hoge", "bomen", "vangen"),
  array("moeten", "we", "rekening"),
  array("voor", "deze", "tijd")
  );    ``

This foreach outputs all the values!

foreach ($test as $val) {

    echo "$val" . "<br/>";
    }

How can i output only the values of column 2? instead of the values of all the columns.

I want this output:

bomen
we
deze

Please post what the expected output would be in this example — Rizier123

This should work for you:

$test = array(
          array("hoge", "bomen", "vangen"),
          array("moeten", "we", "rekening"),
          array("voor", "deze", "tijd")
        );   

               //vv Go trough each innerArray
foreach($test as $v) 
    echo $v[1] . "<br />";
       //^^^^^ Print the second element of each innerArray

Output:

bomen
we
deze

Also for more information about arrays see the manual: http://php.net/manual/en/language.types.array.php (The manual is always a good reference to search for things and learn it :D)

@Fille You're welcome! Enjoy your day :D (FYI: If you have a php problem just do a quick google search with keywords of the problem, search it in the manual (php.net) and or try a little bit debugging :D)

If you wanted to display the elements of the first inner array, then

foreach($test[0] as $value) echo $value."\n";

I think he wants the first element of EVERY inner array.

This code can solve the problem:

$test = array
(
  array("hoge", "bomen", "vangen"),
  array("moeten", "we", "rekening"),
  array("voor", "deze", "tijd")
  );
  for($i=0; $i<count($test);$i++) {
    echo $test[$i][1];
}

If foreach is not your choice.

It depends what do you mean by column, but this is probably what you are looking for

$column = 0;
foreach ($test as $val) {
    echo $val[$column];
}

Prints the value for the column number, which is set in the $column variable.

<?php
    $test = array(
        array("hoge", "bomen", "vangen"),
        array("moeten", "we", "rekening"),
        array("voor", "deze", "tijd")
    );

    $column = 1; // number of the column you want
    array_map(function($v) use ($column) {
        echo $v[$column-1] . " ";
    },$test);
?>

Try:

$test2 = array_map( 
                    function($element){ 
                        return $element[0]; 
                    },  
                    $test 
          );

$element[0] is the element you want it from each array, and do a foreach for $test2 or print inside closure.

Or use:

$arr = array_column($test, 0);

0 is the index key you want to keep. do a foreach on $arr.
