php对特殊格式文件的操作

[zhusnow]

例：
src user {
ip 192.168.1.30
}

time testTime {
weekly smw
}
acl {
user within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
}
}
如何写入到acl{ 里面，且读取出user，TestTime，及movies ，politics 等

[CunningBoy]

可以考虑用正则，但是挺复杂的。
这样的文件结构，你没有考虑在输出的时候时候用xml代替？

[xuzuning]

这样说吧，把用你的例子想要得到的结果贴出来

[zhusnow]

src user {
ip 192.168.1.30
}

time testTime {
weekly smw
}
acl {
user within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
}
name within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
}
uname within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
}
}
每保存一次
都把 uname within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
} 写入到acl{}内

谁能帮忙写正则表达式与foo-clients within workhours ，缩进一个Tab
acl {
admin {
pass any
}
foo-clients within workhours {
pass !adv !aggressive !alcohol !automobile_bikes any
} else {
pass any
}
}

[xuzuning]

$s = <<< TEXT
src user {   
  ip 192.168.1.30
}   
    
time testTime {
  weekly smw  
}
acl {
  user within TestTime {
  pass !movies !politics !news !video !forum any
  }else {  
  pass any
  }   
}
TEXT;

function foo($s) {
  preg_match('/acl\s+{(.+)}/is', $s, $p); //提取 acl 中的内容
  preg_match('/(.+within TestTime {.+}.+})/isU', $p[1], $r); //提取第一节
  $s = str_replace($p[1], $p[1].$r[1], $s);
  return $s;
}
//执行一次
echo $s = foo($s);
//再执行一次，看看效果是你要的吗？
echo $s = foo($s);

我想读取把
user within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
} 类型的数据一次写入到acl{}里面，我用正则表达式可以脱去外面的一层acl{}，但匹配不了user within TestTime

[helloyou0]

读出来用正则等一步步分析啊,
别人没法说什么详细的,因为不知道你这个文件里的含义和约定.

不知道你遇到的困难在哪里?

[zhusnow]

帮忙写一个只匹配string winthin string的正则表达式,
src user {
ip 192.168.1.30
}

time testTime {
weekly smw
}
acl {
user within TestTime {
pass !movies !politics !news !video !forum any
}else {
pass any
}
}
是从一个文件中读取的，是一行行的数组

[xuzuning]

$s = " user within TestTime {
";
$p = "/^\s*\w+\s+within\s+\w+/i";

echo preg_match($p, $s, $r) ? 'yes' : 'no';


从文件读取内容也要写吗？
