`Parlour!' he echoed sneeringly, `parlour! Nay, we've noa parlours. If yah dunnut loike wer company, there's maister's; un' if yah dunnut loike maister, there's us.
`Then I shall go upstairs!' I answered; `show me a chamber.' I put my basin on a tray, and went myself to fetch some more milk. With great grumblings, the fellow rose, and preceded me in my ascent: we mounted to the garrets; he opening a door, now and then, to look into the apartments we passed.
`Here's a rahm,' he said, at last, flinging back a cranky board on hinges. `It's weel eneugh tuh ate a few porridge in. They's a pack o' corn i' t' corner, thear, meeterly clane; if yah're feared uh muckying yer grand silk cloes, spread yer hankerchir o' t' top on't.'
The `rahm' was a kind of lumber-hole smelling strong of malt and grain; various sacks of which articles were piled around, leaving a wide, bare space in the middle.
`Why, man!' I exclaimed, facing him angrily,coach outlet, `this is not a place to sleep in. I wish to see my bedroom.
`Bed-rume!' he repeated, in a tone of mockery. `Yah's see all t' bed-rumes thear is--yon's mine.'
He pointed into the second garret, only differing from the first in being more naked about the walls, and having a large, low, curtainless bed, with an indigo-coloured quilt at one end.
`What do I want with yours?' I retorted. `I suppose Mr Heathcliff does not lodge at the top of the house, does he?'
`Oh! it's Maister Hathecliff's yah're wenting!' cried he, as if making a new discovery. `Couldn't ye uh said soa, at onst? un then, Aw mud uh telled ye, baht all this wark,christian louboutin uk, ut that's just one yah cannut sea--he alIas keeps it locked, un nob'dy iver mells on't but hisseln.'
`You've a nice house, Joseph,' I could not refrain from observing, `and pleasant inmates; and I think the concentrated essence of all the madness in the world took up its abode in my brain the day I linked my fate with theirs! However, that is not to the present purpose--there are other rooms. For heaven's sake be quick, and let me settle somewhere!'
He made no reply to this adjuration; only plodding doggedly down the wooden steps, and halting before an apartment which, from that halt and the superior quality of its furniture, I conjectured to be the best one. There was a carpet: a good one, but the pattern was obliterated by dust; a fireplace hung with cut paper, dropping to pieces; a handsome oak bedstead with ample crimson curtains of rather expensive material and modern make; but they had evidently experienced rough usage: the valances hung in festoons, wrenched from their rings, and the iron rod supporting them was bent in an arc on one side, causing the drapery to trail upon the floor. The chairs were also damaged, many of them severely; and deep indentations deformed the panels of the walls. I was endeavouring to gather resolution for entering and taking possession, when my fool of a guide announced, `This here is t' maister's.' My supper by this time was cold, my appetite gone,clarks shoes, and my patience exhausted. I insisted on being provided instantly with a place of refuge,clarks shoes uk, and means of repose.
PHP中 这个 preg_match_all 匹配url 的正则该怎么写？<?php
$string='<a href= " ccc">
<a href= " ccc">
<a href= " ccc">
';
preg_match_all("/http:\/\/www\..*? /",$string,$array);
//print_r($array);
foreach ($array[0] as $u){
$url = $u;
echo $url."<br>";
}
//$url就是你要的结果,或者
for($i=0;$i<count($array[0]);$i++){
$url=$array[0][$i];
echo $url."<br>";
}
?>
PHP多行匹配解决 我要匹配中间: 我用了 if (preg_match('/([^"]*)/', $str, $reg))要匹配<li></li>中间多行数据,用正则表达式:<li>([\s\S]*?)<\/li>
取第一捕获组的数据就可以了.
php如何使用正则表达式匹配url图片啊可以这样：
$image = ""
preg_match("/(http:\/\/)?\w+\.jpg/",$image,$matches);//http://可要可不要
echo $matches[0];//$matches[0]即为匹配的图片路径
以上只是匹配jpg类型的图片
如果要匹配其他类型可以这样使用
preg_match("/(http:\/\/)?\w+\.(jpg|jpeg|gif|png)/",$image,$matches);
echo $matches[0];
php 正则表达式 url匹配1，preg_grep（pattern，array）;它的返回值是一个新数组，新数组的元素是成功匹配的元素。
2，preg_match（mode，string）;它的返回值是一个整数，0或1,0表示匹配不成功，1表示匹配成功，preg_match（）将在第一个匹配成功后停止搜索，不再继续匹配。
3，preg_match_all（模式，字符串，保存匹配结果数组（multidimensional array））;在搜索字符串中，所有匹配的模式都提供正则表达式的匹配结果，并以指定的顺序将它们输出到指定的数组。它执行与字符串末尾匹配的全局正则表达式匹配。
4，preg_quote（string）;转义正则表达式字符，preg_quote（）需要一个参数字符串，并在每个正则表达式语法中为该字符添加反斜杠。
5，转换效果如图所示。
php如何匹配所有URI？注意是URI,不是URL和URN.URL与URN的关系
URI可被视为定位符（URL），名称（URN）或两者兼备。统一资源名（URN）如同一个人的名称，而统一资源定位符（URL）代表一个人的住址。换言之，URN定义某事物的身份，而URL提供查找该事物的方法，URL包含协议但是URN不包含协议。
