How can I output only the values of subarrays? - php

Question

I have an array and I want to output some data:
array(4) {
[123]=>
array(2) {
["color"]=>
string(3) "red"
["name"]=>
string(5) "harry"
}
[345]=>
array(2) {
["color"]=>
string(4) "blue"
["name"]=>
string(4) "fred"
}
["animal"]=>
string(5) "horse"
["plant"]=>
string(4) "tree"
}
This is my solution, which I have the feeling is very unsmart:
echo "<b>These are all the colors:</b><br>";
foreach ($properties as $key => $val) {
if ($key != "plant" AND $key != "animal"){
echo $val['color']."<br>";
}
}
echo "<b>This is the animal:</b><br>";
foreach ($properties as $key => $val) {
if ($key == "animal"){
echo $val."<br>";
}
}
echo "<b>This is the plant:</b><br>";
foreach ($properties as $key => $val) {
if ($key == "plant"){
echo $val."<br>";
}
}
It gives me the desired result...
These are all the colors:
red
blue
This is the animal:
horse
This is the plant:
tree
...but I thought maybe you know a more simple solution. I am sure it must be possible to talk only to subarrays, but I couldn't find a way to do it.

Answer 1

Since php 5.5, you can use array_column:
$color = array_column($properties, 'color');
Since php 5.3, you can use array_map with an anonymous function, like this:
$color = array_map(function ($ar) {return $ar['color'];}, $properties);
print_r($color);
exit;

I think, Use Switch in foreach and it will help for this problem.
foreach ($properties as $key => $val) {
switch($key){
case '':
break;
}
}
