1.首先添加文件，app/Helpers.php ，我这里是这个名字因为习惯了，你也可以自己定义
<?php
if( !function_exists("getFileName") ){
/**
* 从路径中获取文件名
* @param $fileName
* @return string
*/
function getFileName($fileName)
{
$suffix = substr(strrchr($fileName,'.'),0);
return basename($fileName, $suffix);
}
}
if( !function_exists("getFileExt") ){
/**
* 从路径中获取文件扩展名
* @param $fileName
* @return string
*/
function getFileExt($fileName)
{
$str = strrev($fileName);
return strrev(strchr($str,'.',true));
}
}
if( !function_exists("getFileInfo") ){
/**
* 从路径中获取文件扩展名
* @param $fileName
* @return string
*/
function getFileInfo($fileName, $type)
{
if($type == PATHINFO_EXTENSION){
return getFileExt($fileName);
}else if($type == PATHINFO_FILENAME){
return getFileName($fileName);
}
}
}
2.修改根目录下composer.json 作自动加载刚刚的文件
"autoload": {
"psr-4": {
"App\\": "app/",
"Database\\Factories\\": "database/factories/",
"Database\\Seeders\\": "database/seeders/"
},
"files": [
"app/helpers.php"
]
},
3.修改完成后记得运行 composer dumpautoload 确保让修改生效
composer dumpautoload
