After really long research, no solution was found. So stackoverflow is my last hope.

In PHP I need a parser for data getting from a postgreSQL DB.

The string construct is like:

"keytext {this is my value text 1} key with multi words {value text 2} another key {key_value number 3}"

So we have the key (could consist of several words) and the value in curly braces.

I think, this data type comes from TCL.

How can we convert this string to a JSON-String or an array in PHP 7/8 ??

THANK you VERY MUCH FOR trying to help me!.

Is not a perfect way but it's work.

$string = "keytext {this is my value text 1} key with multi words {value text 2} another key {key_value number 3}";

$results = explode('{', $string);
$newArray = $values = [];
 
foreach ($results as $result){
    if (strpos($result, '}') !== false) {
        $values[] = explode('}', $result)[0];
        $keys[] = explode('}', $result)[1];
    } else {
        $keys[] = $result;
    }
}

$newArray = [];

foreach ($keys as $index => $key) {
    if ($key !== '' && isset($values[$index])){
        $newArray[$key] = $values[$index];
    }
}
return $newArray;

Check this out

$str = "keytext {this is my value text 1} key with multi words {value text 2} another key {key_value number 3}";
$chars = str_split($str);

$result_arr = [];
$make_arr_key = true;
$make_arr_key_val = false;
$arr_key = '';
$arr_key_val = '';
foreach ($chars as $char) {
    if($char == '{') {
        $make_arr_key = false;
        $arr_key_val = '';
        $make_arr_key_val = true;
    }

    if($char == '}') {
        $result_arr[trim($arr_key)] = trim($arr_key_val);
        $arr_key = '';
        $make_arr_key = true;
        $make_arr_key_val = false;
    }

    if($make_arr_key) {
        if($char != '}'){
            $arr_key .= $char;
        }
    }

    if($make_arr_key_val) {
        if($char != '{') {
            $arr_key_val .= $char;
        }
    }

}
print_r($result_arr);

Output:
