十進制數用逗號或點後，第一個數字

Question

EDIT 2

謝謝大家的幫助！ 通過融合我設法解決這個問題的答案以及其他一些論壇帖子：

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

，並顯示現在正確的價格。 「7,49」我自動將PHP腳本轉換爲。

對不起，我不能給更多的問題回答標記。案件結案。

來吧傢伙

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

這將呼應7,4,9，而不是7.49。但是這個代碼是迄今爲止最好的代碼。 有人有任何想法如何解決這個問題？

嗯，我被困在這，現在一會兒..

我從一個網站分析數據，我想要得到的價格，但在網站上有價格之間沒有逗號或點。因此，它顯示像499，4是大於99

當我這樣做：

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

它會響應499 我希望它4和99

之間添加逗號或點

我已經試過：

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

這將呼應：

這：

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

這將呼應：

, 
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，將蟹每個頁面上的價格，同時也呼應的HTML代碼。它拆分了html代碼而不是價格。

下面是該網站

<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> 

我在做什麼錯上的HTML代碼？我嘗試過不同的方式，但沒有成功。有人可以幫助我用正確的代碼嗎？

感謝

Answer 1

試試這個，添加strip_tags它刪除任何HTML標籤：

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

Answer 2

不管發生的簡單的解決方案？

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

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

甚至：

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

（如果你是快樂的默認格式浮動）

Answer 3

也許這將解決你的問題。

$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 

但您還可以在代碼中解析您的<sup>標記。

請您試試;

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

$數[0]是多個以逗號之前的陣列

$號碼[1]是數後逗號

也許這有助於陣列;

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

Answer 4

如果我理解正確的問題，你可以剝去標籤，乘以10的價格，然後用number_format。之後，你只需要去掉最後一位數字。

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

由於它是phpQuery你可以使用：

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

要獲取的實際數據的後。

但是這可能是更接近你以後：

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

這將產生一個陣列 - 在這種情況下 - 兩個元素，4和99

UPDATE ：

要打印的價格的方式，你想要的，使用：

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

更新2：

的phpQuery選擇也許應該是這個樣子：

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"; 
} 

這將遍歷每個div.item-prijs並提取價格到一個數組，$價格。
