Question about array's

[eldan88]

Hey,

 

 I am trying to figure out how I can pull an array that is within an array. I have trying doing that but not getting any luck.

 

Below is an example code that I am trying to work with, but its only returning the letter "G" Any suggestions? 

$name_array = array("dog",array("cat"));
echo $name_array[0][2];

<?php

$name_array_original = array (

                          0 => array('animal' => 'dog'),

                      1 => array('animal' => 'cat'),

                      2 => array('animal' => 'tiger')

                   );


$name_array = array (

                       0 => array('animal' => 'dog' , 'name' => 'Snoopy'),

                   1 => array('animal' => 'cat', 'name' => 'Garfield'),

                   2 => array('animal' => 'tiger', 'name' => 'Tony')

                 );

// Name sorting function:

function name_sort($x, $y) {

    return strcasecmp($x['name'], $y['name']);

}


echo '<h2>Original Array</h2><pre>' . print_r($name_array_original, 1) . '</pre>';

uasort($name_array, 'name_sort');

echo '<h2>Array Sorted By Name</h2><pre>' . print_r($name_array, 1) . '</pre>';


foreach ($name_array_original as $original) {

    foreach ($original as $key => $value) {

        echo '<p>Key = ' . $key . '<br>Value = ' . $value . '</p>';

    }

}

$name_array[0] is the string "dog",

so

$name_array[0][2] is the third letter of "dog"

[Eiseth]

Try using is_array() to check whether the next element is an array

foreach ($name_array as $arr)
{
    // only arrays will process
    if (is_array($arr))
    {
        $arrays = $arr;
    }
}

print_r($arrays); // array([0]=>'cat')

echo $name_array[1][0];

Yes, get used to print_r()

 

 

print_r($name_array);
/*
Array
(
    [0] => dog
    [1] => Array
        (
            [0] => cat
        )


)
*/
