explode() into $key=>$value pair

Question

I have this:

$strVar = \"key value\";

And I want to get it in this:

array(\'key\'=>\'value\')

I tried

Answer 1

If you have more values in a string, you can use array_walk() to create an new array instead of looping with foreach() or for(). I'm using an anonymous function which only works with PHP 5.3+.

// your string
$strVar = "key1 value1&key2 value2&key3 value3";

// new variable for output
$result = array();

// walk trough array, add results to $result
array_walk(explode('&', $strVar), function (&$value,$key) use (&$result) {
    list($k, $v) = explode(' ', $value);
    $result[$k] = $v;
});

// see output
print_r($result);

This gives:

Array
(
    [key1] => value1
    [key2] => value2
    [key3] => value3
)

Answer 2

$pairs = explode(...);
$array = array();
foreach ($pair in $pairs)
{
    $temp = explode(" ", $pair);
    $array[$temp[0]] = $temp[1];
}

But it seems obvious providing you seem to know arrays and explode. So there might be some constrains that you have not given us. You might update your question to explain.

Answer 3

list($array["min"], $array["max"]) = explode(" ", "key value");

Answer 4

I am building an application where some informations are stored in a key/value string.

tic/4/tac/5/toe/6

Looking for some nice solutions to extract data from those strings I happened here and after a while I got this solution:

$tokens = explode('/', $token);

if (count($tokens) >= 2) {
    list($name, $val) = $tokens;
    $props[$name] = $val;
}

if (count($tokens) >= 4) {
    list(, , $name, $val) = $tokens;
    $props[$name] = $val;
}

if (count($tokens) >= 6) {
    list(, , , , $name, $val) = $tokens;
    $props[$name] = $val;
}

// ... and so on

freely inspired by smassey's solution

This snippet will produce the following kinds of arrays:

$props = [
    'tic' => 4,
];

or

$props = [
    'tic' => 4,
    'tac' => 5,
];

or

$props = [
    'tic' => 4,
    'tac' => 5,
    'toe' => 6,
];

my two cents

Answer 5

$my_string = "key0:value0,key1:value1,key2:value2";

$convert_to_array = explode(',', $my_string);

for($i=0; $i < count($convert_to_array ); $i++){
    $key_value = explode(':', $convert_to_array [$i]);
    $end_array[$key_value [0]] = $key_value [1];
}

Outputs array

$end_array(
            [key0] => value0,
            [key1] => value1,
            [key2] => value2
            )

Answer 6

Another single line:

parse_str(str_replace(' ', '=', $strVar), $array);
