how to trim white space in array in php - php

Question

I have an array which contains some words. I want to get all words as unique part. so when I come to a whitespace , it's broken to a new. I mean , finally I want something like this:
$output[0]='Aug',
$output[1]='20',
$output[2]='2016'
first I want to explode it , then trim between words . this is my code but unfortunately doesn't work.Aug 20 come together. I want them individually.
<?php
$firs_arr=new array();
$first_arr='Aug 20, 2016 ';
$second=explode(',',$first_arr);
$output=array_map('trim',$second);

Answer 1

If you call your source $source, then $result below is the array you want:
//split into parts separated by all non-word characters
$result = preg_split('/\W+/',trim($source));

John John:
You can have a complete array with all the information of a given date inside a string, with the function date_parse: http://php.net/manual/en/function.date-parse.php
Code:
$first_arr='Aug 20, 2016 ';
print_r(date_parse($first_arr));
Output:
Array ( [year] => 2016 [month] => 8 [day] => 20 [hour] => [minute] => [second] => [fraction] => [warning_count] => 0 [warnings] => Array ( ) [error_count] => 0 [errors] => Array ( ) [is_localtime] => )

Answer 3

You can also try it:
<?php
function replaceComma($var){
return str_replace(',','',trim($var));
}
$first_arr='Aug 20, 2016 ';
$second=explode(' ',trim($first_arr));
$second=array_map('replaceComma',$second);
var_dump($second);
?>

Answer 4

array_map and trim can do the job
$trimmed_array=array_map('trim',$first_array);
print_r($trimmed_array);
