Returning Array From Functions PHP

Returning Array From Functions PHP

The purpose of this tutorial is to explain how to return and array from a function, which will become part of another array. With PHP, you can return a string or array from a function. The string or array that is returned can become combined into another array.

<?php
include('connect.inc');
$db=public_db_connect();

$count = 0;
function get_data($var1,$date){
global $db; 


$my_values[] = $var1.",".$date;
return $my_values; //return an array
}
 
$command = "SELECT DISTINCT id, email FROM table_sort WHERE id IN (1,2,3,4,5,6,7) ORDER BY id ASC ";
$result = mysqli_query($db, $command);
 
while($row = mysqli_fetch_assoc($result)) {
$var1 = $row['id'];
 
$command2= "SELECT min(date) as date FROM table_sort WHERE id ='$var1' ORDER BY id ASC";
$result2 = mysqli_query($db, $command2);
 
while($row2 = mysqli_fetch_assoc($result2)){
 
$date = $row2['date'];
echo $var1."-".$date."<br/>";
$get_data = get_data($var1,$date);
$my_array[] = $get_data;
}
}

print_r($my_array);

foreach ($my_array as $key => $value) {
$value = implode(",",$value);
echo "<br/>".$key."-".$value;
$value2 = str_replace(",","-",$value);
echo "<br/>".$value2;

}
?>
