I have the array below:
$test = array(
'key_a' => array('a', 'b'),
'key_b' => array('c', 'd')
);
and I want to convert in the format below:
$test = array(
array(
'key_a' => 'a',
'key_b' => 'c'
),
array(
'key_a' => 'b',
'key_b' => 'd'
)
);
Is it possible? How can I do this?
I think you can use something like the following:
$test = array(
'key_a' => array('a', 'b'),
'key_b' => array('c', 'd')
);
$max_length = 0;
$data = array();
foreach($test as $key => $value) { //Find the max_length of all subarrays
$this_length = count($value);
if ($this_length > $max_length) {
$max_length = $this_length;
}
}
for($i = 0; $i < $max_length; $i++) { //For all subarray's values (horizontal)
foreach($test as $key => $value) { //Foreach array (vertical)
if (isset($value[$i])) { //If the value is set
$data[$i][$key] = $value[$i];
}
}
}
var_dump($data);
Result:
array (size=2)
0 =>
array (size=2)
'key_a' => string 'a' (length=1)
'key_b' => string 'c' (length=1)
1 =>
array (size=2)
'key_a' => string 'b' (length=1)
'key_b' => string 'd' (length=1)
Also works for uneven arrays:
$test = array(
'key_a' => array('a', 'b', 'M'),
'key_b' => array('c', 'd',)
);
Result:
array (size=3)
0 =>
array (size=2)
'key_a' => string 'a' (length=1)
'key_b' => string 'c' (length=1)
1 =>
array (size=2)
'key_a' => string 'b' (length=1)
'key_b' => string 'd' (length=1)
2 =>
array (size=1)
'key_a' => string 'M' (length=1)
One of the solutions would be:
$test = array(
'key_a' => array('a', 'b'),
'key_b' => array('c', 'd')
);
$result = array();
foreach ($test as $arrays) {
$result = array_merge_recursive(
$result,
array_combine(
array_keys($test),
array_chunk($arrays, 1)
)
);
}
foreach ($result as $key => &$value) {
$value = array_combine(array_keys($test), $value);
}
echo '<pre>';
print_r($result);
echo '</pre>';
The result would be:
Array
(
[key_a] => Array
(
[key_a] => a
[key_b] => c
)
[key_b] => Array
(
[key_a] => b
[key_b] => d
)
)
Go through your array and rebuild the new one in the same time.
function arrayTranspose($myArray) {
$result = array();
foreach ($myArray as $mainKey => $subArray) {
foreach ($subArray as $subKey => $value) {
if (!isset($result[$subKey]))
$result[$subKey] = array();
$result[$subKey][$mainKey] = $value;
}
}
return $result;
}
Yes, it is possible. You can use array_values - This function returns all the values from the array and indexes the array numerically.
Try this:
<?php
$test = array(
'key_a' => array('a', 'b'),
'key_b' => array('c', 'd')
);
$test = array_values($test);
echo '<pre>';
print_r( $test );
echo '</pre>';
$array = array_values($array);....
