PHP: foreach loop assign the values of an array to a concatenated string and variable

I want to assign the values of an array to a string with a variable:

    $my_array_values = array("apple", "orange", "cellular", "box");

//my function
function my_function ($my_array_values, $string) {
foreach ($my_array_values as $my_array_value) {
$string_query = $string;
 echo $string_query . "<br>";
}
}

//string to loop the variable inside the foreach
$string_variable = "SELECT login FROM table WHERE login = '" . $my_array_value . "'";
my_function ($my_array_values, $string_variable);

If I echo it, the result is this (not taking the array values of the variable):

    SELECT login FROM table WHERE login = ''
SELECT login FROM table WHERE login = ''
SELECT login FROM table WHERE login = ''
SELECT login FROM table WHERE login = ''

The result should be like this:

    SELECT login FROM table WHERE login = 'apple'
SELECT login FROM table WHERE login = 'orange'
SELECT login FROM table WHERE login = 'cellular'
SELECT login FROM table WHERE login = 'box'

How I can do that? Kind regards

What is it you are trying to achieve? The MySQL IN function looks for values "IN" a subset or other pool of info.

$query= "SELECT login FROM table WHERE login IN ({implode(',', $my_array_values)})";

Would this be easier than looping over and over?

No need to create extra variables in your function. Simply echo what was passed along with the value extracted from the array that was passed.

$my_array_values = array("apple", "orange", "cellular", "box");

//my function
function my_function ($my_array_values, $string) {

    foreach ($my_array_values as $my_array_value) {
        echo $string . $my_array_value . "'<br>";
    }

}  // end of my_function

//string to loop the variable inside the foreach
$string_variable = "SELECT login FROM table WHERE login = '";
my_function ($my_array_values, $string_variable);

The correct way is like this:

$my_array_values = array("apple", "orange", "cellular", "box");

//my function
function my_function ($my_array_values, $string) {
  foreach ($my_array_values as $my_array_value) {
    $string_query = $string . $my_array_value . "'";
     echo $string_query . "<br>";
  }
}

//string to loop the variable inside the foreach
$string_variable = "SELECT login FROM table WHERE login = '" ;
my_function ($my_array_values, $string_variable);
