Explode a string to associative array without using loops? [duplicate]

Answer 1

Technically, it is possible to do this without using loops (demo on codepad.org):

$string = '1-350,9-390.99';

// first, split the string into an array of pairs
$output = explode(',', $string);
function split_pairs ($str) {
    return explode('-', $str, 2);
}
$output = array_map(split_pairs, $output);

// then transpose it to get two arrays, one for keys and one for values
array_unshift($output, null);
$output = call_user_func_array(array_map, $output);

// and finally combine them into one
$output = array_combine($output[0], $output[1]);

var_export($output);

However, this is really not something you'd want to do in real code — not only is it ridiculously convoluted, but it's also almost certainly less efficient than the simple foreach-based solution others have already given (demo on codepad.org):

$output = array();
foreach ( explode( ',', $string ) as $pair ) {
    list( $key, $val ) = explode( '-', $pair, 2 );
    $output[$key] = $val;
} 

Answer 2

Something like this should work:

$string = '1-350,9-390.99';

$a = explode(',', $string);

foreach ($a as $result) {
    $b = explode('-', $result);
    $array[$b[0]] = $b[1];
}

Answer 3

This uses array_walk with a closure.

<?php
$string = "1-350,9-390.99";
$partial = explode(',', $string);
$final = array();
array_walk($partial, function($val,$key) use(&$final){
    list($key, $value) = explode('-', $val);
    $final[$key] = $value;
});
print_r($final);
?>

Answer 4

$x='1-350,9-390.99';
$arr1=explode(',',$x);
$res_arr=array();
foreach($arr1 as $val){
    $arr2=explode('-',$val);
    $res_arr[$arr2[0]]=$arr2[1];
    }

print_r($res_arr);

Answer 5

Try this:

$string = '1-350,9-390.99';
$array = explode(',', $string);

$output = array();
foreach($array as $arr){
    $chunk = explode('-', $arr);
    $output[$chunk[0]] = $chunk[1];
}
echo '<pre>'; print_r($output); echo '</pre>';

Answer 6

Is this the thing you want?

<?php 
//the string to process
$str = "1-350,9-390.99";

//explode it
$str_exploded = explode(",",$str);

$final_arr;
foreach($str_exploded as $str_elem){
    //extract
    $str_elem_final = explode("-",$str_elem);
    //the first elem is the index and the last elem is the value
    $final_arr[(int)$str_elem_final[0]] = $str_elem_final[1];

}
print_r($final_arr);
