其中几个函数很好用,我花了一天时间
直接创建多层目录mymkdir($dirname),
批处理目录下的文件function listDirTree( $dirName = null ,$callFunction) 可自定义处理函数。
如:
$callFunc="backupFile(\"$backupPath\",\$file,\$filePath,\$dirName);";
listDirTree($operateDir,$callFunc);
listDirTree($operateDir,$callFunc);
将文本中 x=y
u=a
提取为数组的函数
function myExplode($originalStr,$firstTag,$secondTag)
将文件转换为utf-8编码的函数。function gb2utf8($file,$filePath)
判断文件是否为utf-8编码的函数 function utf8_probability(&$rawtextstr)
