PHP Separate line into variables

Question

i have text with many lines like this:

(item (Index Value) (Name Value)(Name2 Value2)(Name3 Value3) (Speciality (Name-a value-a)  (Name-b value-b))

Real example:

(item(name 256)(Index 1)(Image "Wea001")(Action 1 1)(class weapon sword)(code 1 1 1 1)(country 2)(level 1)(wear 1)   (limit Knight 1)(range 16)(buy 4)(sell 1)(endurance 4)(specialty(aspeed 700)(Attack 3 10)(hit 15)))

Now i want to save them in array $Items[$Index] -index value is the (Index XX) in the line-

and in each value new array contain the values in this, for example (using the real line)

$Items[1]{
$Name => 256,
$Image => 'Wea001',
$Action=> '1 1',
$class => 'weapon sword',
...etc
}

i already saved them in the master array using the explode, but using default values 0,1,2,3,..etc not the Index of the line

$items = explode('<br />', $inititemcontent);
for($i = 0; $i < count($items); $i++){
    echo "$items[$i] <br />";
}

PS: the index value never repeated, there can never be 2 lines with the same index PPS: not usually all the small tags (Name Value) exist, some times all of them, some times only some.

Answer 1

I was noticing that the format of the original file was similar to JSON after I wrote the first answer, so I wrote this:

    <?php
    $string = '(item(name 256)(Index 1)(Image "Wea001")(Action 1 1)(class weapon sword)(code 1 1 1 1)(country 2)(level 1)(wear 1)   (limit Knight 1)(range 16)(buy 4)(sell 1)(endurance 4)(specialty(aspeed 700)(Attack 3 10)(hit 15)))';



    $patterns = array(
    '!\(!',
    '!\)!',
    '!\{([^\{}]+)\{!',
    '!\},\},\}!',
    '!\},([^}])!',
    '!\{([^ ]+) ([^}]+)\}!',
    '!"!',
    "!'!",
    "!\}(,)?!",
    "!\},$!",
    );
    $replacements = array(
    "{",
    "},",
    "{\"$1':[\n{'",
    "}]}]}",
    "},\n$1",
    "{'$1':'$2'}",
    '',
    '"',
    "}$1\n",
    "}"
    );

    $string = preg_replace($patterns,$replacements,$string);
    //print $string;
    $items = json_decode($string,true);

    print_r($items);

    ?>

Output Source looks like this:

Answer 2

Would something like this work? Since there is only one line for the example I didn't have much to go on.

<?php
    $string = '(item(name 256)(Index 1)(Image "Wea001")(Action 1 1)(class weapon sword)(code 1 1 1 1)(country 2)(level 1)(wear 1)   (limit Knight 1)(range 16)(buy 4)(sell 1)(endurance 4)(specialty(aspeed 700)(Attack 3 10)(hit 15)))';

    preg_match_all('!\([^()]+\)!s',$string,$parts);

    $items = array();


    foreach($parts as $index=>$temp_array){
        foreach($parts[$index] as $key=>$component){
            $component = preg_replace('![()]!','',$component);
            preg_match_all('!([^ ]+) ([^)]+)!',$component,$component_parts);

            $temp_key = $component_parts[1][0];
            $temp_val = $component_parts[2][0];
            $items[$index][$temp_key]=$temp_val;
        }
    }

    print_r($items);

?>

Output looks like this:

Array
(
[0] => Array
    (
        [name] => 256
        [Index] => 1
        [Image] => "Wea001"
        [Action] => 1 1
        [class] => weapon sword
        [code] => 1 1 1 1
        [country] => 2
        [level] => 1
        [wear] => 1
        [limit] => Knight 1
        [range] => 16
        [buy] => 4
        [sell] => 1
        [endurance] => 4
        [aspeed] => 700
        [Attack] => 3 10
        [hit] => 15
    )

)
