PHP loading array of objects - object

Question

I'd like to load my array with objects from .csv
When I do it with writing JSON like a forced string, its okay and my code works fine.
When I try to make objects and load them into an array, new object overwrites all objects in the array and I got an array full of the same values. Any suggestions for my mistakes?
In the end, variable content gives valid JSON (without '[]' brackets), but array contentArr gives array full of same objects...
Here´s the code:
$content = '';
$contentArr = array();
$Obj = new stdClass();
$count = 0;
while ($csv = fgetcsv($file,1000,",")) {
$content .= "{\"number\":\"".$csv[0]=Filter($csv[0])."\",\"message\":\"".$csv[1]."\"},";
$count++;
$Obj -> number = $csv[0]=Filter($csv[0]);
$Obj -> message = $csv[1];
$contentArr[] = $Obj;
}
$content = substr($content, 0, -1);

Answer 1

I hope this code can help you
$openFile = fopen($file, "r");
while(!feof($openFile)){
$csv = fgetcsv($file);
//your code here
}
fclose($openFile);

Answer 2

SOLVED MYSELF.
My mistake was that I was changing link only to one object I made before the while cycle. When I move object creating INTO the while cycle, I am creating new object for every new data I am loading into array.
Code:
$content = '';
$contentArr = array();
//$Obj = new stdClass(); ----> this was my mistake
$count = 0;
while ($csv = fgetcsv($file,1000,",")) {
$content .= "{\"number\":\"".$csv[0]=Filter($csv[0])."\",\"message\":\"".$csv[1]."\"},";
$count++;
$Obj = new stdClass();// ----> that's how it should be
$Obj -> number = $csv[0]=Filter($csv[0]);
$Obj -> message = $csv[1];
$contentArr[] = $Obj;
}
$content = substr($content, 0, -1);
