PHP简单源码学习
书上的源代码,好多个,每个都要敲就烦死了,
上网扣了段遍历文件的代码:http://www.web589.com/posts/808.html
作者写得不错的嘛,注释非常详细


"; function directory($dir){ $dp = opendir($dir); while($file = readdir($dp)){ if($file !="." && $file !=".."){ $path=$dir. "/". $file; /* 取得目录路径 */ if(is_dir($path)){ /* 判断是否有子目录 */ directory($path); /* 函数递归调用 */ echo "

"; } else{ printf(''.$path.'

'); } } } closedir($dp); } directory(".");?>



   $number = "5";               # $number is a string   $sum = 15 + $number;   	# Add an integer and string to produce integer   print("$sum\n");
