删除操作,平日里面多见于网盘。通过删除操作,我们可以批量地完成删除多文件的一个任务。说到批量删除,那就不得不提到批量获取给定目录下面的目录路径了。删除文件呢,遍历是一个非常之必要的过程,没有遍历就没有办法获取相应的文件路径,才能准确地删除掉目录下面的文件。而我们应该怎么去获取目录下面所有子目录的路径呢,这也算是一个比较关键的一点哦。下面我直接上代码了:这里用到的函数是glob,返回的将是一个数组!!
代码
<?php ? ?? function?getDirs($directory){? ?? ????$opt?=?array();? ?? ????foreach(glob(str_replace("//","/","$directory/*"),GLOB_ONLYDIR)?as?$dir){? ?? ????????$opt[]?=?str_replace($directory,"",$dir);? ?? ????}? ?? ????return?$opt;? ?? }? ?? //获取顶级目录的所有目录?也就是这个文件所在目录的同级目录?然后把数组打印出来 ?? print_r(getDirs('../'));? ?? ?>??
