How to convert PHP array to be used in JavaScript script

Question

Hi i have an array like that

Array ( [0] => Array ( [t_name] => London, Heathrow ) 
        [1] => Array ( [t_name]   => Lilongwe, Malawi ) 
        [2] => Array ( [t_name] => Harare,Zimbabwe ) 
        [3] => Array ( [t_name] => Lahore,Pakistan ) 
        [4] => Array ( [t_name] => Accra, Ghana ) 
        [5] => Array ( [t_name] => Entebbe, Uganda ) 
        [6] => Array ( [t_name] => Nairobi ) 
        [7] => Array ( [t_name] => Abuja, Nigeria )
)

and I want it to be converted to be used in JavaScript. its supposed to look like that I have tried json_encode() but it converts it something like that

[{"t_name":"London, Heathrow"},{"t_name":"Lilongwe, Malawi"},
{"t_name":"Harare,Zimbabwe"},{"t_name":"Lahore,Pakistan"},{"t_name":"Accra, Ghana"},
{"t_name":"Entebbe, Uganda"},{"t_name":"Nairobi"},{"t_name":"Abuja, Nigeria"}]

but i want it to be converted like that

[
 "London, Heathrow",
 "Lilongwe, Malawi",
 "Harare,Zimbabwe",
 "Lahore,Pakistan",
 "Accra, Ghana",
 "Entebbe, Uganda",
 "Nairobi",
 "Abuja, Nigeria",
 "Lagos, Nigeria"
 ]

If you want a different structure in the output, then adjust your input accordingly ... — Sirko, Jul 07 '15 at 10:16

Before json_encode your array you need to get first the values of that single column which is t_name using array_column and echo the resultant array. Try it as

$arr = Array (Array ( 't_name' => 'London, Heathrow' ),Array ( 't_name'   => 'Lilongwe, Malawi' ),Array ( 't_name' => 'Harare,Zimbabwe' ),Array (   't_name' => 'Lahore,Pakistan' ),Array ( 't_name' => 'Accra, Ghana' ),Array ( 't_name' => 'Entebbe, Uganda' ),Array ( 't_name' => 'Nairobi' ),Array ( 't_name' => 'Abuja, Nigeria' ));
echo json_encode(array_column($arr,'t_name'));

Fiddle

i am getting the result array from the database by using the codeigniters own methods and above is what it returns – Zohaib Jul 07 '15 at 10:20
You might be storing that array within variable just place that variable within as `echo json_encode(array_column($your_array,'t_name'));` and that's it if the value that you have posted within your question looks like that then it'll surely work – Narendrasingh Sisodia Jul 07 '15 at 10:22
okay both your and @Barmar way work gives me the arrays but there are spaces in them now how to remove them i am basically want to use them in auto-complete input feild. – Zohaib Jul 07 '15 at 10:29

Use a loop to extract the names into a simple array:

$new_array = array();
foreach ($array as $obj) {
    $new_array[] = str_replace(' ', '', $obj['t_name']);
}
echo json_encode($new_array);

there are spaces in them how to remove them? – Zohaib Jul 07 '15 at 10:26
Why do you need to remove them? You have spaces in the desired output. – Barmar Jul 07 '15 at 10:28
But if you want to use them, use `str_replace()`. WTP? – Barmar Jul 07 '15 at 10:28
i am creating an autocomplete input feild so the spaces will be a mess in them and how to use srt_replace() in arrays i have used it for strings but not for arrays – Zohaib Jul 07 '15 at 10:31
Use it on the strings when you're assigning them to the array. I've updated the answer. – Barmar Jul 07 '15 at 10:34
Why did you show the spaces in the desired output if you wanted them removed? – Barmar Jul 07 '15 at 10:35
