php - Why is the array is always empty at this point despite the fact that I added data there?
Get the solution ↓↓↓$result = mysqli_query($con, "SELECT * FROM users");
$usersArray=[];
tableArrayPushData($result, $usersArray);
function tableArrayPushData($result, $tableArray){
while ($row = $result->fetch_assoc()) {
$str = '';
foreach ($row as $value) {
$str = $str.$value.'|';
}
$newStr = rtrim($str, "| ");
array_push($tableArray,$newStr);
}
}
for ($i=0; $i<count($usersArray); $i++){//array is always empty at this point
echo "Ok";
echo "<br>";
}
I don't understand why, butusersArray
is empty despite the fact that I added data there.
The MySQL table has rows with data, so it can't be empty.
