# palindromic primes challenge

I don't understand the feedback message: The \$sum variable does not have the correct value. Call the mimic_array_sum function, and store the return value in the \$sum variable.

could anyone help'

palindromic_primes.php
```<?php

function mimic_array_sum(\$array) {
\$sum = 0;
foreach(\$array as \$element) {
\$sum = \$sum + \$element;
};
return \$sum;

};

\$sum = mimic_array_sum();

\$palindromic_primes = array(11, 757, 16361);

?>
```

This is the code I just used to pass:

```<?php

function mimic_array_sum(\$array) {
foreach (\$array as \$value) {
\$x += \$value;
}
return \$x;
}

\$palindromic_primes = array(11, 757, 16361);

\$sum = mimic_array_sum(\$palindromic_primes);

echo \$sum;

?>
```

Notice there are no semicolons after the }. The function is called after the array \$palindromic_primes is defined.
