To convert a multidimensional array into a single array in PHP, you can use the array_merge() function recursively. Here is an example:
function flatten_array($array) {
$result = array();
foreach ($array as $value) {
if (is_array($value)) {
$result = array_merge($result, flatten_array($value));
} else {
$result[] = $value;
}
}
return $result;
}
$multi_array = array(array('a', 'b'), array('c', 'd'), array('e', 'f', 'g'));
$single_array = flatten_array($multi_array);
print_r($single_array);
In this example, the flatten_array() function recursively calls itself to flatten the multidimensional array. The array_merge() function is used to merge the resulting arrays into a single array. The output of the code above will be:
Array
(
[0] => a
[1] => b
[2] => c
[3] => d
[4] => e
[5] => f
[6] => g
)
As you can see, the multidimensional array has been flattened into a single-dimensional array.
