如何从GLOB阵列中生成此可变大小的表输出图像？

Question

I have to make a table with an amount of columns that can be set by a variable ($cols) with each cell containing a picture obtained through a GLOB Array. The code I have now will output a table with the correct amount of cells and columns but I need help getting each picture to show up.

<?php
$cols = 4;

$array = glob("include/*.{jpg}", GLOB_BRACE);


$output = "<table>
";

$cell_count = 1;

for ($i = 0; $i < count($array); $i++) {
    if ($cell_count == 1) {
        $output .= "<tr>
";
    }
    $output .= "<td><img src=$array></td>
";
    $cell_count++;

    if ($cell_count > $cols || $i == (count($array) - 1)) {
        $output .= "</tr>
";
        $cell_count = 1;
    }
}
$output .= "</table>
";
echo "$output";

?>

Answer 1

You are not indexing into the array to get a single item. This:

$output .= "<td><img src=$array></td>
";

should be

$output .= "<td><img src=\"$array[$i]\"></td>
";

Note also that I am escaping the double quotes so that your HTML src attribute value is double quoted.

Also, you could make the for statement more efficient if you cache count($array) in another variable, although it might not be a big deal.
