[SOLVED] Convert a string with 2 delimiters into a flat associative array

Convert a string with 2 delimiters into a flat associative array

Here is a string..

$string = "foo1 : bar1, foo2: bar2, foo3: bar3";

Exploding using , delimeter

$exploded = (",", $string);

Now the $exploded array contains:

foo1 : bar1
foo2 : bar2
foo3 : bar3

Now I need to put foo1 in an array['key'] and bar1 in array['value']

How to achieve this?

Solution

You'll need to create another loop to go through an array of "foo:bar" strings and explode them:

$exploded = explode(",", $input);  
$output = array();       //Array to put the results in
foreach($exploded as $item) {  //Go through "fooX : barX" pairs
  $item = explode(" : ", $item); //create ["fooX", "barX"]
  $output[$item[0]] = $item[1];  //$output["fooX"] = "barX";
}
print_R($output);

Note that if the same key appears more than once in the input string - they will overwrite each other and only the last value will exist in the result.
