Create an array with a string

Question

i'm trying to do a thing but i don't know how :) I have a php string in this format:

$test = (1 / 2015-11-2 11:11:11, 2 / 2015-07-07 11:11:11, ......)

I need a function that process that string to get as format:

$testarray = array(
    "id" => "1",
    "date" => "2015-11-2 11:11:11",

    "id" => "2",
    "date" => "2015-07-07 11:11:11",

   .....
    );

I thought these steps:

1) find how many comma are present in $test string using

substr_count($test, ",");

2) take the string before the comma and find in this string value " / "

3) Create the array

Can you help me?

You can't do this, one key in one array only. tow id or two date can't be in one array. — Niklesh Raut

The function you need to use is explode. You can check the documentation here

First, like you said, you need to separate the string into "substrings" using the comma separator:

$firstArr = explode(',', $test);

This will return an array of strings like this:

$firstArr = [ "1 / 2015-11-2 11:11:11", "2 / 2015-07-07 11:11:11",... ]

After that you can use explode one more time on each string that the array above contains:

$result = array();   //The resulting array
foreach($firstArr as $str)
{
    $secondArr = explode('/', $str); // specific delimiter '/'
    $result[] = array(
        'id' => trim($secondArr[0]),//trim removes blank spaces if any
        'date' => trim($secondArr[1])
    );
}

$secondArr will be like this:

$secondArr = ['1', '2015-11-2 11:11:11']

That is why you need to use $secondArr[0] to get the id and $secondArr[1] to get the date

Explode is the best way, but as variant you can use regex

(?<=\(|,)\s*(?P<id>\d+)\s+\/\s*(?P<date>[^,\)]+)(?=,|\))

which returns such result

MATCH 1
id  [1-2]   `1`
date    [5-23]  `2015-11-2 11:11:11`
MATCH 2
id  [25-26] `2`
date    [29-48] `2015-07-07 11:11:11`

demo and some explanation

The solution using preg_match_all and array_walk functions:

$test = "1 / 2015-11-2 11:11:11, 2 / 2015-07-07 11:11:11";
$result = [];
preg_match_all("/(\d+?) \/ (\d{4}-\d{2}-\d{1,2} \d{2}:\d{2}:\d{2})/", $test, $m, PREG_SET_ORDER);
array_walk($m, function($v, $k) use(&$result){
    $result[] = ['id'=> $v[1], 'date' => $v[2]];
});

print_r($result);

The output:

Array
(
    [0] => Array
        (
            [id] => 1
            [date] => 2015-11-2 11:11:11
        )

    [1] => Array
        (
            [id] => 2
            [date] => 2015-07-07 11:11:11
        )
)
