PHP Integrating PHP with Databases Limiting Records in SQL Pagination Function

Pagination Function

This is such an easy objective.... except I can't seem to figure out the last step?

  1. Move all the code that sets the $pagination variable inside the pagination function.
  2. Return the $pagination variable.
  3. Change the echo on the final line to call the function instead of the variable. Make sure you pass the four variables: \$total_pages, \$current_page, \$section, \$search.

I'm getting this error: Bummer! PHP Parse error: syntax error, unexpected '$total_pages' (T_VARIABLE), expecting identifier (T_STRING) in /workdir/index.php on line 28 Parse error: syntax error, unexpected '$total_pages' (T_VARIABLE), expecting identifier (T_STRING) in /workdir/index.php on line 28

index.php 
<?php
include "pagination.php";

/* add function here */
function pagination($total_pages, $current_page, $section, $search){
/* setting pagination variable */
$pagination = "<div class=\"pagination\">";
$pagination .= "Pages: ";  
for ($i = 1;$i <= $total_pages;$i++) {
    if ($i == $current_page) {
        $pagination .= " <span>$i</span>";
    } else {
        $pagination .= " <a href='catalog.php?";
        if (!empty($search)) {
            $pagination .= "s=".urlencode(htmlspecialchars($search)) . '&' ;
        } else if (!empty($section)) {
            $pagination .= "cat=".$section . '&';
        }
        $pagination .= "pg=$i'>$i</a>";
    }
}
$pagination .= "</div>";

return $pagination;
}

/* displaying the pagination */
pagination(\$total_pages, \$current_page, \$section, \$search);

I fooled around with it a little and completed the challenge :D looks like you didn't need to break out with \ on line 28

<?php
include "pagination.php";

/* add function here */
function pagination($total_pages, $current_page, $section, $search){
/* setting pagination variable */
$pagination = "<div class=\"pagination\">";
$pagination .= "Pages: ";  
for ($i = 1;$i <= $total_pages;$i++) {
    if ($i == $current_page) {
        $pagination .= " <span>$i</span>";
    } else {
        $pagination .= " <a href='catalog.php?";
        if (!empty($search)) {
            $pagination .= "s=".urlencode(htmlspecialchars($search)) . '&' ;
        } else if (!empty($section)) {
            $pagination .= "cat=".$section . '&';
        }
        $pagination .= "pg=$i'>$i</a>";
    }
}
$pagination .= "</div>";

return $pagination;
}

/* displaying the pagination */
echo pagination($total_pages, $current_page, $section, $search);

I swear before I made this post I had written the exact answer you provided and it kept giving me: Task 1 is no longer passing! But it worked this go around.... thanks!
