Combine two arrays
(11 answers)
Closed 6 years ago.
I'm new at PHP so forgive me if this question has been asked. How do you combine two PHP arrays into one? This is the code I'm using that needs to be combined:
<?php $duplicates[] = get_the_ID(); ?>
<?php $images = get_attached_media( 'image', $post->ID );?>
Thanks for the help.
If all you need to do is merge two arrays into one, this should do the trick:
$new_array = array_merge($duplicates, $images);
Array Combine Procedure
Code:
<?php
$a1=array("red","green");
$a2=array("blue","yellow");
print_r(array_merge($a1,$a2));
?>
Output:
Array ( [0] => red [1] => green [2] => blue [3] => yellow )
PHP function array_combine creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values.

A variable called $result
When print_r ($result);
It goes:
Array
(
[0] => iPhone
)
Array
(
[0] => iOS
)
Array
(
[0] => Safari
)
Seems like there are 3 Arrays in this $result, but I want to marge it to one and give theme order, I've tried array_merge(), and array_combine(), but none of theme get the result I want, what I really want is:
Array( 'iPhone', 'iOS', 'Safari' )
So I could output one of them using $results[0] or $results[1]...
How can I achieve that? Thanks alot.
Use array_merge with ... splat operator
$result = array_merge(...$array);
OR
$result = call_user_func_array('array_merge', array($a));

'username'=>name,'avatar'=>4.jpg
i.e., merge the same key values in the above format..
How should I do this,..Someone help me..
If you think that my title is wrong,Please change it into correct format.

Use array_combine()
$final_array = array_combine($fist_array,$second_array);

PHP multidimensional array search by value
(23 answers)
Closed 3 years ago.
Is there any predefined PHP function to find a key in a multi dimensional array?
In the below example - there is a variable name 'rose' and I need to get the key of the array by using the variable name.
The result of the key is "flower".
$array = array (
'fruits' => array (
'mango',
'cherry'
),
'flowers' => array (
'rose'
)
);
How do I achieve this?
Loop it up using a foreach
$keyword='mango';
foreach($array as $k=>$arr)
{
if(in_array($keyword,$arr))
{
echo $k;break;// "prints" fruits
}
}

Flatten a multidimensional array and remove duplicate values [duplicate]
(3 answers)
Closed 8 years ago.
How can I remove duplicate values from a multidimensional array in PHP like below.
I tried Remove duplicate value in multidimensional array. But did not solve my problem.
Array(
[0] => outdoor
[1] => indoor
)
Array(
[0] => indoor
)
Result should be a single array like below :
array(outdoor,indoor);
finally i found the result from Remove duplicate value in multidimensional array. I'll share them for other users.
$result = array_unique(call_user_func_array('array_merge',$result2));
Use array_unique to remove duplicates from a single array.
Use array_merge to combine arrays.
Try:
array_unique(array_merge($array1,$array2), SORT_REGULAR);
$array = array(array("outdoor","indoor"),array("indoor"));
$result = array_unique($array);
print_r($result[0]);
Demo
Try this:
<?php
$Arr = array(array('outdoor','indoor'),array('indoor'));
$result = array_unique($Arr);
$newArr = $result[0];
echo '<pre>';
print_r($newArr);
?>
The result will be
Array
(
[0] => outdoor
[1] => indoor
)

multidimensional array

I have this:
Array
(
[28] => Array
(
[name] => HTC Touch HD
)
)
There's only one array inside the main array and I only the value of name. Problem is that I don't know the index (28).
You could use array_values just in general to get rid of any weird keys:
$normal = array_values($arr);
$normal[0]['name']
Or in this particular case, end, which is only a little bit hacky:
end($normal)['name']
http://codepad.viper-7.com/cApBjK
(Yep, reset and first and such work too.)
You could also just use
$array = array_pop($array);
And then to get the name element:
$array['name']
You can try something like this:
reset($outerArray);
$innerArray = current($outerArray);
Now you should have access to the value you want.
Pretty self-explanatory :)
<?php
$array = array(
28 => array(
'name' => 'HTC Touch HD'
)
);
$key = current(array_keys($array));
echo '<pre>';
print_r($array[$key]);
echo '</pre>';
?>
If you don't know the structure of an array, you can use foreach construct.
