Question:
How to merge cells with HTML, CSS, and PHP?

Merging cells in a table is a common requirement when designing a structured and visually appealing layout for web applications. The combined powers of HTML, CSS, and PHP allow you to create seamless table structures. Here, we will tell you the code snippets to effortlessly merge cells, enhancing the presentation and organization of your data-driven web pages. 


Let’s take a simple example of how you can count and do the spans at least for the cols.


";

    foreach ($values as $value) {

        [$content, $repeat] = $value;

        if (1 === $repeat) {

            echo "

";

            continue;

        }

        echo "

";

    }

    echo "

\n";

}

$rows = [

    [1, 2, 3, 4, 5, 6],

    [1, 1, 1, 2, 2, 2],

    [1, 2, 2, 2, 2, 3],

];


foreach ($rows as $row) {

    $values = [];

    $prev = null;

    $repeat = 0;

    foreach ($row as $value) {

        if ($value === $prev) {

            $repeat++;

            continue;

        }

        if ($prev !== null) {

            $values[] = [$prev, $repeat];

        }

        $repeat = 1;

        $prev = $value;

    }

    $values[] = [$value, $repeat];

    echo "

$content$content

Part 2 - Detecting identical rows

In this part, we will tell the process of detecting identical rows within HTML tables using the combined capabilities of HTML, CSS, and PHP.

];


for ($index = 0, $count = count($datas); $index < $count; ++$index) {

    $sameRowCount = countSameRows($index, $datas);

    echo "row $index has the next $sameRowCount rows with the first 6 columns in common\n";

        }

        $sameCount++;

    }


    return $sameCount;

}


row 0 has the next 0 rows with the first 6 columns in common

row 1 has the next 4 rows with the first 6 columns in common

row 2 has the next 3 rows with the first 6 columns in common

row 3 has the next 2 rows with the first 6 columns in common
