Turn any array into a Text Table

Question

I have this code that turns any array into a text table, it works almost perfectly, if you find any bugs please tell me..

function arr2textTable($table) {
    function clean($var) { 
        $search=array("`((?:https?|ftp)://\S+[[:alnum:]]/?)`si","`((?<!//)(www\.\S+[[:alnum:]]/?))`si");
        $replace=array("<a href=\"$1\" rel=\"nofollow\">$1</a>","<a href=\"http://$1\" rel=\"nofollow\">$1</a>");
        $var = preg_replace($search, $replace, $var);
        return $var;
    }
    foreach ($table AS $row) {
        $cell_count = 0;
        foreach ($row AS $key=>$cell) {
            $cell_length = strlen($cell);
            $key_length = strlen($key);
            $cell_length = $key_length > $cell_length ? $key_length : $cell_length;
            $cell_count++;
            if (!isset($cell_lengths[$key]) || $cell_length > $cell_lengths[$key])
                $cell_lengths[$key] = $cell_length;
        }   
    }
    $bar = "+";
    $header = "|";
    foreach ($cell_lengths AS $fieldname => $length) {
        $bar .= str_pad("", $length+2, "-")."+";
        $name = $fieldname;
        if (strlen($name) > $length) {
            $name = substr($name, 0, $length-1);
        }
        $header .= " ".str_pad($name, $length, " ", STR_PAD_RIGHT) . " |";
    }
    $output = "${bar}\n${header}\n${bar}\n";
    foreach ($table AS $row) {
        $output .= "|";
        foreach ($row AS $key=>$cell) {
            $output .= " ".str_pad($cell, $cell_lengths[$key], " ", STR_PAD_RIGHT) . " |";
        }
        $output .= "\n";
    }
    $output .= $bar."\n";
    return clean($output);
}

$table=json_decode([{"OS":"Debian","Stars":"10","Link":"http://debian.org/"},{"OS":"Linux Mint Debian","Stars":"9","Link":"http://linuxmint.com/"},{"OS":"Fedora","Stars":"9","Link":"http://fedoraproject.org/"}]);
echo arr2textTable($table);

Returns:

+-------------------+-------+---------------------------+

| Fedora            | 9     | http://fedoraproject.org/ |

Answer 1

I have self-solved my own question Here is the new code:

function arr2textTable($a, $b = array(), $c = 0) {
    $d = array();
    $e = "+";
    $f = "|";
    $g = 0;
    foreach ($a as $h)
        foreach ($h AS $i => $j) {
            $j = substr(str_replace(array("\n","\r","\t","  "), " ", $j), 0, 48);
            $k = strlen($j);
            $l = strlen($i);
            $k = $l > $k ? $l : $k;
            if (!isset($d[$i]) || $k > $d[$i])
                $d[$i] = $k;
        }
    foreach ($d as $m => $h) {
        $e .= str_pad("", $h + 2, "-") . "+";
            if (strlen($m) > $h)
                $m = substr($m, 0, $h - 1);
            $f .= " " . str_pad($m, $h, " ", isset($b[$g]) ? $b[$g] : $c) . " |";
            $g++;
    }
    $n = "{$e}\n{$f}\n{$e}\n";
    foreach ($a as $h) {
        $n .= "|";
        $g = 0;
        foreach ($h as $i => $o) {
            $n .= " " . str_pad($o, $d[$i], " ", isset($b[$g]) ? $b[$g] : $c) . " |";
            $g++;
        }
        $n .= "\n";
    }
    $p = array(
        "`((?:https?|ftp)://\S+[[:alnum:]]/?)`si",
        "`((?<!//)(www\.\S+[[:alnum:]]/?))`si"
    );
    $q = array(
        "<a href=\"$1\" rel=\"nofollow\">$1</a>",
        "<a href=\"http://$1\" rel=\"nofollow\">$1</a>"
    );
    return preg_replace($p, $q, "{$n}{$e}\n");
}

Answer 2

This should be what you are looking for. You will need to write a function to pass GET params in as rows to the ArrayToTextTable function but it will work.

Answer 3

There is some code to do exactly that at the URL linked below.

Sample output:

Table width (number of columns) can be adjusted.
