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

$strVar = "key value";
list($key, $val) = explode(' ', $strVar);

$arr= array($key => $val);

Edit: My mistake, used split instead of explode but:

split() function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged

Answer 2

Try this

$str = explode(" ","key value");
$arr[$str[0]] = $str[1];

Answer 3

If you have more than 2 words in your string, use the following code.

    $values = explode(' ', $strVar);

    $count = count($values);
    $array = [];

    for ($i = 0; $i < $count / 2; $i++) {
        $in = $i * 2;
        $array[$values[$in]] = $values[$in + 1];
    }

    var_dump($array);

The $array holds oddly positioned word as key and evenly positioned word $value respectively.

Answer 4

You can loop every second string:

$how_many = count($array);
for($i = 0; $i <= $how_many; $i = $i + 2){
  $key = $array[$i];
  $value = $array[$i+1];
  // store it here
}

Answer 5

You can try this:

$keys = array();
$values = array();

$str = "key value"; 
$arr = explode(" ",$str);

foreach($arr as $flipper){
   if($flipper == "key"){
      $keys[] = $flipper;
   }elseif($flipper == "value"){
      $values[] = $flipper;
   }
}

$keys = array_flip($keys);
// You can check arrays with
//print_r($keys);
//print_r($values);

foreach($keys as $key => $keyIndex){
  foreach($values as $valueIndex => $value){
       if($valueIndex == $keyIndex){
          $myArray[$key] = $value;
       }
  }
}

I know, it seems complex but it works ;)

Answer 6

Single line for ya:

$arr = array(strtok($strVar, " ") => strtok(" "));
