十进制数用逗号或点后，第一个数字

Question

EDIT 2

谢谢大家的帮助！ 通过融合我设法解决这个问题的答案以及其他一些论坛帖子：

$string = strip_tags($oNode['div.item-prijs']); 
$array = str_split($string,1); 
$arraytotal = ($array[0] . ',' . $array[1] . $array[2]); 
echo $arraytotal; 

，并显示现在正确的价格。 “7,49”我自动将PHP脚本转换为。

对不起，我不能给更多的问题回答标记。案件结案。

来吧家伙

$price = strip_tags($oNode['div.item-prijs']); 
$new_price = substr(chunk_split($price, 1, ','), 0, -1); 
echo $new_price; 

这将呼应7,4,9，而不是7.49。但是这个代码是迄今为止最好的代码。 有人有任何想法如何解决这个问题？

嗯，我被困在这，现在一会儿..

我从一个网站分析数据，我想要得到的价格，但在网站上有价格之间没有逗号或点。因此，它显示像499，4是大于99

当我这样做：

$price = $oNode['div.item-prijs']; 
echo $price; 

它会响应499 我希望它4和99

之间添加逗号或点

我已经试过：

$price = $oNode['div.item-prijs']; 
$new_price = substr(chunk_split($price, 1, ','), 0, -1); 
echo $new_string; 

这将呼应：

这：

$string = $oNode['div.item-prijs']; 
    $new_string = substr(chunk_split($string, 4, ','), 0, -1); 
    echo $new_string; 

这将呼应：

, 
7,49<,/sup,>, 

<,/p><,/div,>, 

4,99<,/sup,>, 

1,49<,/sup,>, 

0,69<,/sup,>, 

1,99<,/sup,>, 

1,49<,/sup,>, 

1,49<,/sup,>, 

3,49<,/sup,>, 

3,49<,/sup,>, 

3,69<,/sup,>, 

1,19<,/sup,>, 

1,89<,/sup,>, 

1,99<,/sup,>, 

1,99<,/sup,>, 

1,49<,/sup,>, 

2,99<,/sup,>, 

1,99<,/sup,>, 

1,09<,/sup,>, 

2,25<,/sup,>, 

1,99<,/sup,>, 

0,99<,/sup,>, 

1,54<,/sup,>, 

2,09<,/sup,>, 

1,78<,/sup,>, 

1,71<,/sup,>, 

0,99<,/sup,>, 

1,49<,/sup,>, 

2,08<,/sup,>, 

1,49<,/sup,>, 

3,49<,/sup,>, 

6,18<,/sup,>, 

3,99<,/sup,>, 

4,29<,/sup,>, 

2,79<,/sup,> 

因此，将蟹每个页面上的价格，同时也呼应的HTML代码。它拆分了html代码而不是价格。

下面是该网站

<div class="item-prijs"> 
     <p> 
      <cufon class="cufon cufon-canvas" alt="4" style="width: 27px; height: 42px; "> 
       <canvas width="47" height="43" style="width: 47px; height: 43px; top: -1px; left: -2px; "></canvas> 
       <cufontext>4</cufontext> 
      </cufon> 
      <sup> 
       <cufon class="cufon cufon-canvas" alt="99" style="width: 24px; height: 20px; "> 
        <canvas width="35" height="21" style="width: 35px; height: 21px; top: -1px; left: -1px; "> 
        </canvas><cufontext>99</cufontext> 
       </cufon> 
      </sup> 
     </p> 
    </div> 

我在做什么错上的HTML代码？我尝试过不同的方式，但没有成功。有人可以帮助我用正确的代码吗？

感谢

Answer 1

试试这个，添加strip_tags它删除任何HTML标签：

$price = strip_tags($oNode['div.item-prijs']); 
$new_price = substr(chunk_split($price, 1, ','), 0, -1); 
echo $new_string; 

Answer 2

不管发生的简单的解决方案？

$major = intval($price/100); 
$minor = intval($price) % 100; 

echo "The price is $major.$minor.\n"; 

甚至：

echo "The price is " . ($price/100) ".\n"; 

（如果你是快乐的默认格式浮动）

Answer 3

也许这将解决你的问题。

$price = $oNode['div.item-prijs']; 
$new_price = substr(chunk_split($price, 1, ','), 0, -1); 
echo $new_price; // not $new_string; I think $new_string is an other var in your code 

但您还可以在代码中解析您的<sup>标记。

请您试试;

$preg='#<div class="item-prijs"><p>(.*?)<sup>(.*?)</sup></p></div>#si'; 
preg_match_all($preg,$new_string,$number,PREG_SET_ORDER); 

$数[0]是多个以逗号之前的阵列

$号码[1]是数后逗号

也许这有助于阵列;

$string = $oNode['div.item-prijs']; 
$new_string = substr(chunk_split($string, 4, ','), 0, -1); 
echo str_replace("<,/sup,>,", "", $new_string); 

Answer 4

如果我理解正确的问题，你可以剥去标签，乘以10的价格，然后用number_format。之后，你只需要去掉最后一位数字。

php -r 'echo substr(number_format((499*10)), 0, -1);' => 4,99 
php -r 'echo substr(number_format((599*10)), 0, -1);' => 5,99 
php -r 'echo substr(number_format((5099*10)), 0, -1);' => 50,99 

Answer 5

由于它是phpQuery你可以使用：

echo trim ($oNode['div.item-prijs']->text()); 

要获取的实际数据的后。

但是这可能是更接近你以后：

$price = array(); 
foreach ($oNode['div.item-prijs cufontext'] as $n) 
{ 
     $price[] = (int)pq ($n)->text(); 
} 

这将产生一个阵列 - 在这种情况下 - 两个元素，4和99

UPDATE ：

要打印的价格的方式，你想要的，使用：

echo $price[0] . '.' . $price[1]; 

更新2：

的phpQuery选择也许应该是这个样子：

foreach (pq ($oNode)->find ('div.item-prijs') as $price_node) 
{ 
    // we're iterating each <div /> class 'item-prijs'. 
    $price = array(); 
    foreach (pq ($price_node)->find ('cufontext') as $pn) 
    { 
     // iterate each <cufontext /> child node to div.item-prijs 
     $price[] = (int)pq ($n)->text(); 
    } 

    // we could add $price to an array or something, but we'll just echo for now. 
    echo $price[0] . '.' . $price[1] . "\n"; 
} 

这将遍历每个div.item-prijs并提取价格到一个数组，$价格。
