display data from SQL database into php/ html table [closed]

Answer 1

Here's a simple function I wrote to display tabular data without having to input each column name: (Also, be aware: Nested looping)

function display_data($data) {
    $output = '';
    foreach($data as $key => $var) {
        $output .= '';
        foreach($var as $k => $v) {
            if ($key === 0) {
                $output .= '';
            } else {
                $output .= '';
            }
        }
        $output .= '';
    }
    $output .= '
' . $k . '
' . $v . '
';
    echo $output;
}

UPDATED FUNCTION BELOW

Hi Jack,

your function design is fine, but this function always misses the first dataset in the array. I tested that.

Your function is so fine, that many people will use it, but they will always miss the first dataset. That is why I wrote this amendment.

The missing dataset results from the condition if key === 0. If key = 0 only the columnheaders are written, but not the data which contains $key 0 too. So there is always missing the first dataset of the array.

You can avoid that by moving the if condition above the second foreach loop like this:

function display_data($data) {
    $output = "";
    foreach($data as $key => $var) {
        //$output .= '';
        if($key===0) {
            $output .= '';
            foreach($var as $col => $val) {
                $output .= "';
            }
            $output .= '';
            foreach($var as $col => $val) {
                $output .= '';
            }
            $output .= '';
        }
        else {
            $output .= '';
            foreach($var as $col => $val) {
                $output .= '';
            }
            $output .= '';
        }
    }
    $output .= '
" . $col . '
' . $val . '
' . $val . '
';
    echo $output;
}

and another update that removes redundant code blocks that hurt maintainability of the code.

function display_data($data) {
$output = '';
foreach($data as $key => $var) {
    $output .= '';
    foreach($var as $k => $v) {
        if ($key === 0) {
            $output .= '';
        } else {
            $output .= '';
        }
    }
    $output .= '';
}
$output .= '
' . $k . '
' . $v . '
';
echo $output;

}
