PHP - How do I access specific array values in nested array? - php

Question

I have an array like this:
Array (
[0] => Array (
[0] => 510
[1] => 984
[2] => 1045
[3] => 2068
[4] => 1054
[5] => 673
)
[1] => Array (
[0] => 1163
[1] => 1982
[2] => 2067
[3] => 3989
[4] => 1940
[5] => 1242
)
[2] => Array (
[0] => june
[1] => july
[2] => august
[3] => september
[4] => october
[5] => november
)
)
I want to access only one of the arrays within the array at a time and echo them out.
For example, I would get: 510, 984, 1045, 2068, 1054, and 673 as one result.
I've looked at multiple threads and answers but nothing that quite solves my issue, I've been able to print out all the values but I just want some specifically.
I'd store it in the variable: $array_item
My most recent attempt was:
foreach ($array_item as $inner) {
if (is_array($inner)) {
foreach ($inner[0] as $value) {
echo "$value \n";
}
}
}
Which gives me: Warning: Invalid argument supplied for foreach().
I thought for sure that would work, what am I doing wrong?

Answer 1

In your code $inner[0] is one of the inner array elements, like 510. You can't loop over that.
If you just want to loop over $array_item[0], don't loop over the whole array.
if (is_array($array_item[0])) {
foreach ($array_item[0] as $value) {
echo "$value\n";
}
}

Answer 2

Does is_array($array_item) return true?
if (is_array($array_item)) {
foreach ($array_item) {
if (is_array($inner)) {
foreach ($inner as $value) {
echo "$value \n";
}
}
}
}
Edit: Also, $inner[0] is not an array. $inner is the array.

I would use implode, http://php.net/manual/en/function.implode.php
foreach($array_items as $items) {
echo implode(', ', $items);
}
I see that a comment was made that he wants only the first array to be outputted and not all of them.
if (is_array($array_item[0])) {
echo implode(PHP_EOL, $array_item[0]);
}

You never can tell what could solve a problem
$array_group = array();
if (isset($array_item[0]) and is_array($array_item[0])) {
foreach ($array_item[0] as $value) {
$array_group[] = $value;
}
$array_group should output
Array
(
[0] => 510
[1] => 984
[2] => 1045
[3] => 2068
[4] => 1054
[5] => 673
)
