任意の配列をテキスト テーブルに変換するこのコードがあります。バグが見つかった場合は、ほぼ完全に機能します。
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) . " |";
