1、对象转数组
function ObjectToArray($data)
{
if (is_object($data)) {
$data = get_object_vars($data);
}
if (is_array($data)) {
return array_map(__FUNCTION__, $data);
} else {
return $data;
}
}2、数组转json数据
function ArrayToJson($data, $type = true)
{
$data = json_encode($data, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT);
if ($type) {
print_r($data);
exit;
} else {
return $data;
}
}3、以数组的形式返回关于文件路径的信息
pathinfo(path, options);
/**
['dirname']: 目录路径
['basename']: 文件名
['extension']: 文件后缀名
['filename']: 不包含后缀的文件名
**/
// path：规定要检查的路径。
/**
options：
PATHINFO_DIRNAME - 只返回 dirname
PATHINFO_BASENAME - 只返回 basename
PATHINFO_EXTENSION - 只返回 extension
PATHINFO_FILENAME - 只返回 filename
**/4、获取PHP代码执行后的结果
<?php
function run_code($code)
{
$file_name = rand() . 'txt';
$content = '<?php $text = ' . $code . ' ?>';
file_put_contents($file_name, $content);
include($file_name);
unlink($file_name);
return $text;
}
?>5、多维数组降维
function ArrMd2Ud($arr)
{
#将数值第一元素作为容器，作地址赋值。
$ar_room = &$arr[key($arr)];
#第一容器不是数组进去转呀
if (!is_array($ar_room)) {
#转为成数组
$ar_room = array($ar_room);
}
#指针下移
next($arr);
#遍历
while (list($k, $v) = each($arr)) {
#是数组就递归深挖，不是就转成数组
$v = is_array($v) ? call_user_func(__FUNCTION__, $v) : array($v);
#递归合并
$ar_room = array_merge_recursive($ar_room, $v);
#释放当前下标的数组元素
unset($arr[$k]);
}
return $ar_room;
}6、字符串加密解密
/**
* $string：需要加解密的字符串；
* $operation：E表示加密，D表示解密；
* $key：自定义密匙
*/
function string($string, $operation, $key = '')
{
$key = md5($key);
$key_length = strlen($key);
$string = $operation == 'D' ? base64_decode($string) : substr(md5($string . $key), 0, 8) . $string;
$string_length = strlen($string);
$rndkey = $box = array();
$result = '';
for ($i = 0; $i <= 255; $i++) {
$rndkey[$i] = ord($key[$i % $key_length]);
$box[$i] = $i;
}
for ($j = $i = 0; $i < 256; $i++) {
$j = ($j + $box[$i] + $rndkey[$i]) % 256;
$tmp = $box[$i];
$box[$i] = $box[$j];
$box[$j] = $tmp;
}
for ($a = $j = $i = 0; $i < $string_length; $i++) {
$a = ($a + 1) % 256;
$j = ($j + $box[$a]) % 256;
$tmp = $box[$a];
$box[$a] = $box[$j];
$box[$j] = $tmp;
$result .= chr(ord($string[$i]) ^ ($box[($box[$a] + $box[$j]) % 256]));
}
if ($operation == 'D') {
if (substr($result, 0, 8) == substr(md5(substr($result, 8) . $key), 0, 8)) {
return substr($result, 8);
} else {
return '';
}
} else {
return str_replace('=', '', base64_encode($result));
}
