❮ PHP Array Reference
An array stores multiple values in one single variable: Example<?php $cars = array("Volvo", "BMW", "Toyota"); echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . "."; ?> Try it Yourself »
What is an Array?An array is a special variable, which can hold more than one value at a time.
If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this: $cars1 = "Volvo"; $cars2 = "BMW"; $cars3 = "Toyota"; However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300? The solution is to create an array! An array can hold many values under a single name, and you can access the values by referring to an index number.
Create an Array in PHPIn PHP, the array() function is used to create an array: In PHP, there are three types of arrays: - Indexed arrays - Arrays with a numeric index
- Associative arrays - Arrays with named keys
- Multidimensional arrays - Arrays containing one or more arrays
Get The Length of an Array - The count() FunctionThe count() function is used to return the length (the number of elements) of an
array: Example<?php $cars = array("Volvo", "BMW", "Toyota"); echo count($cars); ?> Try it Yourself »

PHP Exercises (PHP 4, PHP 5, PHP 7, PHP 8) array_values — Return all the values of an array Descriptionarray_values(array $array ): array Parameters array The array.
Return Values Returns an indexed array of values. ExamplesExample #1 array_values() example
<?php $array = array("size" => "XL", "color" => "gold"); print_r(array_values($array)); ?>
The above example will output: Array
(
[0] => XL
[1] => gold
)

Remember, array_values() will ignore your beautiful numeric indexes, it will renumber them according tho the 'foreach' ordering:
<?php $a = array( 3 => 11, 1 => 22, 2 => 33, ); $a[0] = 44;print_r( array_values( $a )); ==> Array( [0] => 11 [1] => 22 [2] => 33 [3] => 44 ) ?>

Just a warning that re-indexing an array by array_values() may cause you to reach the memory limit unexpectly.
For example, if your PHP momory_limits is 8MB,
and says there's a BIG array $bigArray which allocate 5MB of memory.
Doing this will cause PHP exceeds the momory limits:
<?php
$bigArray = array_values( $bigArray );
?>
It's because array_values() does not re-index $bigArray directly,
it just re-index it into another array, and assign to itself later.

This is another way to get value from a multidimensional array, but for versions of php >= 5.3.x <?php /** * Get all values from specific key in a multidimensional array * * @param $key string * @param $arr array * @return null|string|array */ function array_value_recursive($key, array $arr){ $val = array(); array_walk_recursive($arr, function($v, $k) use($key, &$val){ if($k == $key) array_push($val, $v); }); return count($val) > 1 ? $val : array_pop($val); }$arr = array( 'foo' => 'foo', 'bar' => array( 'baz' => 'baz', 'candy' => 'candy', 'vegetable' => array( 'carrot' => 'carrot', ) ), 'vegetable' => array( 'carrot' => 'carrot2', ), 'fruits' => 'fruits', );var_dump(array_value_recursive('carrot', $arr)); // array(2) { [0]=> string(6) "carrot" [1]=> string(7) "carrot2" } var_dump(array_value_recursive('apple', $arr)); // null var_dump(array_value_recursive('baz', $arr)); // string(3) "baz" var_dump(array_value_recursive('candy', $arr)); // string(5) "candy" var_dump(array_value_recursive('pear', $arr)); // null ?>

Most of the array_flatten functions don't allow preservation of keys. Mine allows preserve, don't preserve, and preserve only strings (default).
<? // recursively reduces deep arrays to single-dimensional arrays // $preserve_keys: (0=>never, 1=>strings, 2=>always) function array_flatten($array, $preserve_keys = 1, &$newArray = Array()) { foreach ($array as $key => $child) { if (is_array($child)) { $newArray =& array_flatten($child, $preserve_keys, $newArray); } elseif ($preserve_keys + is_string($key) > 1) { $newArray[$key] = $child; } else { $newArray[] = $child; } } return $newArray; }
// Tests
$array = Array( 'A' => Array( 1 => 'foo', 2 => Array( 'a' => 'bar' ) ), 'B' => 'baz' );
echo 'var_dump($array);'."\n"; var_dump($array); echo 'var_dump(array_flatten($array, 0));'."\n"; var_dump(array_flatten($array, 0)); echo 'var_dump(array_flatten($array, 1));'."\n"; var_dump(array_flatten($array, 1)); echo 'var_dump(array_flatten($array, 2));'."\n"; var_dump(array_flatten($array, 2)); ?>

<?php /** flatten an arbitrarily deep multidimensional array into a list of its scalar values (may be inefficient for large structures) (will infinite recurse on self-referential structures) (could be extended to handle objects) */ function array_values_recursive($ary) { $lst = array(); foreach( array_keys($ary) as $k ){ $v = $ary[$k]; if (is_scalar($v)) { $lst[] = $v; } elseif (is_array($v)) { $lst = array_merge( $lst, array_values_recursive($v) ); } } return $lst; } ?>

If you are looking for a way to count the total number of times a specific value appears in array, use this function:
<?php
function array_value_count ($match, $array)
{
$count = 0;
foreach (
$array as $key => $value)
{
if ($value == $match)
{
$count++;
}
}
return $count;
}
?>
This should really be a native function of PHP.
How can we get particular data from array in PHP?
Answer: Use the Array Key or Index
If you want to access an individual value form an indexed, associative or multidimensional array you can either do it through using the array index or key.
How do I get all the values of an array?
The array_values() function returns an array containing all the values of an array. Tip: The returned array will have numeric keys, starting at 0 and increase by 1.
The extract() function imports variables into the local symbol table from an array. This function uses array keys as variable names and values as variable values. For each element it will create a variable in the current symbol table. This function returns the number of variables extracted on success.
How can I print just the value of an array in PHP?
Answer: Use the PHP foreach loop
php $colors = array("Red", "Green", "Blue", "Yellow", "Orange"); // Loop through colors array foreach($colors as $value){ echo $value . "<br>"; } ?>
