個(gè)人學(xué)習(xí)筆記
核心源碼如下：
/**
* 打印
* @param array ...$params
* @author klinson
*/
function info(...$params)
{
foreach ($params as $param) {
info_item($param);
}
}
/**
* 打印單個(gè)變量
* @param $param
* @param int $i
* @author klinson
*/
function info_item($param, $i = 0)
{
switch (gettype($param)) {
case "array":
info_array($param, $i);
break;
case "object":
info_object($param, $i);
break;
case "boolean":
echo "bool(".($param ? "true" : "false").")";
break;
case "integer":
echo "int({$param})";
break;
case "string":
echo "string({$param})";
break;
case "double":
echo "float({$param})";
break;
case "null":
echo "null";
break;
case "resource":
echo "resource";
break;
default:
echo "UNKNOWN TYPE";
break;
}
echo PHP_EOL;
}
/**
* 打印數(shù)組
* @param $param
* @param int $i
* @author klinson
*/
function info_array($param, $i = 0)
{
// 前置空格
$space = "";
$num = $i;
while ($num) {
$space .= " ";
$num--;
}
echo "array[".count($param)."]: {".PHP_EOL;
foreach ($param as $key => $item) {
echo $space." [{$key}] => ";
info_item($item, $i+1);
}
echo $space."}";
}
/**
* 打印對(duì)象
* @param $param
* @param int $i
* @author klinson
*/
function info_object($param, $i = 0)
{
// 前置空格
$space = "";
$num = $i;
while ($num) {
$space .= " ";
$num--;
}
echo "object(".get_class($param)."[".count($param)."]): {".PHP_EOL;
foreach ($param as $key => $item) {
echo $space." [{$key}] => ";
info_item($item, $i+1);
}
echo $space."}";
}
測(cè)試代碼：
$a = 1.11;
$b = "a";
$c = [$a, $b];
$d = new stdClass();
$d->aaa = "aaa";
$d->bb = $c;
info($a, $b, $c, $d);
效果如下:
