Laravel 添加自定义全局函数

来源：互联网发布：网络投影机办公编辑：程序博客网时间：2024/05/13 08:50

第一步：在app目录下建立Common文件夹，在文件夹中创建helpers.php

第二步：在artisan中引入require __DIR__.'/app/Common/helpers.php';自动加载

第三步：在public目录下的index.php文件中加入require __DIR__.'/../app/Common/helpers.php';

此时你可以在任意类，模板中使用自定义方法：

例：

<?php

namespace {

use Illuminate\Support\Debug\Dumper;
use Illuminate\Container\Container;

if (!function_exists('is_wechat')) {
function is_wechat()
{
$result = isset($_SERVER['HTTP_USER_AGENT']) ?
strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') : false;
return $result !== false;
}
}

if (!function_exists('dump')) {
function dump()
{
array_map(function ($x) {
(new Dumper)->dump($x);
}, func_get_args());
}
}

if (!function_exists('db_escape')) {
function db_escape($value, $escape_char = '\\', $charsets = ['%', '_'])
{
$escaped = [];

foreach ($charsets as $c) {
$escaped[$c] = $escape_char . $c;
}
//$escaped[$escape_char] = $escape_char . $escape_char;

return strtr($value, $escaped);
}
}

if (!function_exists('asset')) {
function asset($path, $secure = null)
{
$pathinfo = pathinfo($path);
if ($pathinfo && isset($pathinfo['extension']) && ('css' === $pathinfo['extension'])) {
$appVersion = Container::getInstance()->make('config')->get('config.app_version', time());

$path .= "?_v=$appVersion";
}

return Container::getInstance()->make('url')->asset($path, $secure);
}
}

if (!function_exists('format_json_success')) {
function format_json_success($body = null)
{
return array(
'body' => $body,
'status' => 'SUCCESS',
);
}
}

if (!function_exists('format_json_failed')) {
function format_json_failed($error = 'internal_error', $data = [], $status = 'FAILED')
{
$error = trans()->has('errors.' . $error) ? trans('errors.' . $error) : $error;
$body = array_merge(['error' => $error], $data);
return array(
'body' => $body,
'status' => $status,
);
}
}

if (!function_exists('get_ip')) {
function get_ip($ip2long = false)
{
$ip = null;
if (!$ip && getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$ip = getenv('HTTP_CLIENT_IP');
}
if (!$ip && getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$ips = explode(',', getenv('HTTP_X_FORWARDED_FOR'));
if (count($ips) > 0) {
$ip = trim($ips[0]);
}
}
if (!$ip && getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$ip = getenv('REMOTE_ADDR');
}
if (!$ip && isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$ip = $_SERVER['REMOTE_ADDR'];
}
if (!$ip) {
$ip = "0.0.0.0";
}

return $ip2long ? ip2long($ip) : $ip;
}
}

if (!function_exists('format_currency')) {
function format_currency($amount, $decimals = 2, $dec_point = '.' , $thousands_sep = ',')
{
return number_format($amount, $decimals, $dec_point, $thousands_sep);
}
}

if (!function_exists('now')) {
function now()
{
return date('Y-m-d H:i:s');
}
}

if (!function_exists('json_encode_unicode')) {
function json_encode_unicode($data, $options = 0)
{

}

return preg_replace_callback('/(?<!\\\\)\\\\u([0-9a-f]{4})/i',
function ($m) {
$d = pack('H*', $m[1]);
$r = mb_convert_encoding($d, 'UTF8', 'UTF-16BE');
return $r !== "?" && $r !== "" ? $r : $m[0];
}, json_encode($data, $options)
);
}
}
}

namespace Api {

function format_json_success($body = null)
{
return $body;
}

function format_json_failed($code, $error = '', $data = [])
{
if (!$error) {
$error = trans()->has('errors.code.' . $code)
? trans('errors.code.' . $code)
: trans('errors.internal_error');
} else {
$error = trans()->has('errors.' . $error)
? trans('errors.' . $error)
: $error;
}

$body = [
'code' => $code,
'message' => $error,
];
$body = array_merge($body, $data);
return $body;
}

function is_mobile($value)
{
return preg_match('/^1\d{10}$/', $value);
}

function date_format($date, $format = 'Y-m-d H:m:s')
