Converting this (array string ) from a file into php array - php

Question

I have an export from a legacy system which i want to import into an RDBMS solution.
The export file has data as the example below
%a = (
'1' => 'test',
'3' => 'test2',
'44' => 'this is another test()
);
%b = (
'1' => 'super man'
);
%c = (
'username' => 'testing'
);
I wish to get these files into associative php array so that i can iterate into the database table, check if the values exist and save it if it does not exist.
I am stuck with the parsing of the file part.
so far i have been able to reach here
$string = file_get_contents($path);
$params = explode("%", $string); // to separate the main chunks
foreach ($params as $keyvalue) {
if ($keyvalue!='') { //as the file starts with % to truncate the first blank result
$trimmed=substr(trim($keyvalue, ' '), 3, strlen($keyvalue) - 4); // remove this part from the result 'a='
$finalArray = explode(";", $trimmed); // remove the semi column
$array = $finalArray[0];
print_r($array );
echo '<br/>';
echo '<br/>';
echo '<br/>';
echo '<br/>';
}
with the above i do get this output
( "1" => "test", "3" => "test2" ,'44' => 'this is another test())
( '1' => 'super man' )
('username' => 'testing' )
displayed on different lines, i tried json_decode (...,true), unserialise ect to convert this output into array so that i can loop with no success.
Any help will be most welcomed.

try this
$array[] = $finalArray[0];
Because you creating new array everytime. You need to append to the existing array so as to get the desired output.
And my edited code is below
$params = explode("%", $string);
$i = 0;
foreach ($params as $keyvalue) {
if ($keyvalue!='') {
$trimmed=substr(trim($keyvalue, ' '), 3, strlen($keyvalue) - 4);
$finalArray = explode(";", $trimmed);
$array = $finalArray[0];
$newArray = explode(',',substr($array, 1, -1));
foreach($newArray as $arravalue) {
$newArray1 = explode('=>',substr($arravalue, 1, -1));
$finalResultArray[$i][trim(str_replace("'","",$newArray1[0]))] = '"'.trim(str_replace("'","",$newArray1[1])).'"';
}
$i++;
}
}
It gives an output array $finalResultArray with the below format.
Array
(
[0] => Array
(
[1] => "test"
[3] => "test2"
[44] => "this is another test("
)
[1] => Array
(
[1] => "super man"
)
[2] => Array
(
[username] => "testing"
)
)

I made a little tweek with string replace to do the trick, by converting it to a json format replacing the ( by { the => by : and ) by }
it seem to work fine but if there is a neater solution I would like to welcome it.
$string = file_get_contents($path);
$params = explode("%", $string);
foreach ($params as $keyvalue) {
if ($keyvalue!='') {
$trimmed=substr(trim($keyvalue, ' '), 3, strlen($keyvalue) - 4);
$finalArray = explode(";", $trimmed);
$array = $finalArray[0];
print_r($array); // display 1
$string2 = str_replace('(', '{', $array);
$string3 = str_replace(')', '}', $string2);
$string4 = str_replace('=>', ':', $string3);
$ar = json_decode($string4);
echo ('<pre>');
//echo $first; // value
print_r( $ar);
echo('</pre>'); //display 2
die('wa');
echo '<br/>';
echo '<br/>';
echo '<br/>';
echo '<br/>';
}
}
//display 1
( "1" => "test1", "2" => "test2", "3" => "test4")
display 2
stdClass Object
(
[1] => test1
[2] => test2
[3] => test4
)
