PHP从列表中创建关联数组（$ key，$ value）

Question

I have an array that has resulted from an explode() function. The final operation I need to do is to separate each element based on an internal delimeter and load it all into an associative array. Something sort of like the following, which gets me the output ... but I can't figure out how to get my results into an array. Help please?

$string = 
item1:val1

item2:val2

item3:val3

item4:val4


$exploded = explode("
",$string);
foreach($exploded as $iteration) {
list($key, $value) = explode(":",$iteration);
}

Answer 1

Just build the array with the $key and $value:

$exploded = explode("
",$string);
foreach($exploded as $iteration) {
    list($key, $value) = explode(":",$iteration);
    $result[$key] = $value;
}

print_r($result);
