Rebase array keys after unsetting elements [duplicate]
(9 answers)
Closed 8 years ago.
I have an array called $Compare, I used the print_r() function in php:
Array ([2] => Broccoli, raw [3] => Candies, butterscotch [4] => Celery, raw [10] => Apricots, raw)
I want it the keys to be in the correct order: 0,1,2,3 not 2,3,4,10!
In the end it should look like this:
Array ([0] => Broccoli, raw [1] => Candies, butterscotch [2] => Celery, raw [3] => Apricots, raw)
Use array_values:
$Compare = array_values($Compare);

How to echo single value from multidimensional array when key is numeric?

Closed 3 years ago.
I have output like this:
[0] => Array
(
[voice] => Napisy
[quality] => 720
[source] => YouTube
)
[16] => Array
(
[voice] => Napisy
[quality] => 720
[source] => Mega
)
And I want to get source to get output [Youtube, Mega]. Anyone know how to get this without foreach?
You can get source from whole array into another array using array_column.
your above array is $array
$source = array_column($array, 'source');
print_r($source);

I am using print_r on a variable which gives me the following output
Array
(
[0] => 95.2
[1] => 94.7
[2] => 95
[3] => 33.6
)
Array
(
[0] => 100
[1] => 95
[2] => 91.90000000000001
[3] => 33.6
)
I want to split them into two variable dynamically. Like $var1 and $var2. If there were three iterations, i would want it to be three variables. Is it possible in php? In the current scenario i want
$var1= (
[0] => 95.2,
[1] => 94.7,
[2] => 95,
[3] => 33.6
)
and
$var2= (
[0] => 100,
[1] => 95,
[2] => 91.90000000000001,
[3] => 33.6
)
and i want to both to be generated dynamically and if possible i want the count of the iterations as well. Thank you in advance
<?php
$data[]=array(1,2,3);
$data[]=array(5,6,7);
$data[]=array(7,8,9);
//you can add many more here and it will still works fine
foreach ($data as $key=>$value){
$variable_name='var_'.$key;
$$variable_name=$value;
}
print_r($var_0);
print_r($var_1);
print_r($var_2);
Sure it is possible.

Accessing Arrays inside Arrays In PHP

I am working with response from Youtube Data API and I don't know how to read each values in the array.
Array
(
[0] => youtube#channelListResponse
[1] => "X"
[2] => Array (
[totalResults] => 1
[resultsPerPage] => 1
)
[3] => Array (
[0] => Array
(
[kind] => youtube#channel
[etag] => "XX"
[id] => XXX
)
)
)
When I try to access [id] with echo $array[3]['id'] it returns Notice: Undefined offset: 3
AS Max said you can access single value in array in array by
$arrayName[index]['key']
Example You can access 'kind' with
$arrayName[3]['kind']
Since, inner level array is key value paired you need to specify key instead of index.
If you want to access all value, you can do it with foreach loop and check type of each value use'gettype()' method. if type is array then use same function recursively.

I have a function that uses array_filter and it returns what you see above. It will only return one object within the array. I do not know what the array index will be, but I know there will only be one item in the array. Is there an array function that strips down the array and just returns the content of it, since I don't need an array with just one item in it.
You should use:
$x = array_values($yourArrayName);
echo $x[0];
You can also use:
echo current($yourArrayName);

The below code,
$test_array = array("a","b","c","d","e");
echo "<fieldset><pre>";
htmlspecialchars(print_r($test_array));
echo "</pre></fieldset>";
which gives output like,
Array
(
[0] => a
[1] => b
[2] => c
[3] => d
[4] => e
)
I want to remove a specific entry say from index 2 and re-index the array as below,
Array
(
[0] => a
[1] => b
[2] => d
[3] => e
)
How to do that?
Use array_splice
array_splice($test_array, 2, 1);
The second argument is your index that you want to nix and the third is how many elements you want gone.
Try this
unset($test_array[2]);
$test_array = array_values($test_array);
