從多維數組創建的JSON中刪除`\ t`（php）

我使用json_encode()將數組$arrData轉換爲JSON。我從網上收集數據並將其放入php數組中。問題是輸出充滿了製表符。我試過$arrData = trim(preg_replace('/\t/', '', $arrData)); - 但它刪除了\t和陣列內的所有數組。有沒有辦法在不破壞數組結構的情況下刪除所有\t？從多維數組創建的JSON中刪除` t`（php）

我的數組：

$arrData = array(
       "chart" => array(
        "caption" => "Number of visitors last week", 
     "subCaption" => "Bakersfield Central vs Los Angeles Topanga", 
     "captionFontSize" => "14", 
     "subcaptionFontSize" => "14", 
     "subcaptionFontBold" => "0", 
     "paletteColors" => "#0075c2,#1aaf5d,#FF5733,#33B5FF",

     "divLineDashed" => "1", 
     "divLineDashLen" => "1", 
     "xAxisName" => "Day", 
     "showValues" => "0" 
       ) 
      ); 
$actualCategory = array($rowData[0][1], $rowData[0][2], $rowData[0][3], $rowData[0][4], $rowData[0][5], $rowData[0][6], $rowData[0][7]); 
       $a = array( 
       array($rowData[2][1], $rowData[2][2], $rowData[2][3], $rowData[2][4], $rowData[2][5], $rowData[2][6], $rowData[2][7]), 
       array($rowData[5][1], $rowData[5][2], $rowData[5][3], $rowData[5][4], $rowData[5][5], $rowData[5][6], $rowData[5][7]), 
       array($rowData[8][1], $rowData[8][2], $rowData[8][3], $rowData[8][4], $rowData[8][5], $rowData[8][6], $rowData[8][7]), 
       array($rowData[11][1], $rowData[11][2], $rowData[11][3], $rowData[11][4], $rowData[11][5], $rowData[11][6], $rowData[11][7]) 
       ); 


       $arrData['categories'] = array(); 
       $arrData['categories']['category'] = array(); 
       $arrData['dataset'] = array(); 



       foreach ($actualCategory as $value) { 
        array_push($arrData['categories']['category'], 
         array(
          'label' => $value 
         ) 
        ); 
       } 

       $q = 1; 
       for($z = 0;$z <= 3; $z++){ 

       $x[$z] = array('seriesname' => $rowData[$q][0], 'data' => array()); 
        foreach ($a[$z] as $value) { 
         array_push($x[$z]['data'], 
          array(
           'value' => $value 
          ) 
         ); 
        } 
       $q = $q + 3; 
       } 
    $arrData['dataset'] = $x;

從您的JSON數據刪除'\ t'。可能嗎？ – smoqadam

$ smoqadam是的我想從數組或JSON中刪除所有'\ t'。我只需要清晰的值。 – piotr

如果元素是數組，則可以使用'array_walk（）'和遞歸調用函數。半小時後，我可以編寫一個示例 –

更換他們在JSON。確保使用單引號：

$json = str_replace('\t', '', $json);

你的正則表達式也可以工作，但需要三個\：

$json = preg_replace('/\\\t/', '', $json);

爲了得到\t和周圍的空間使用：

$json = preg_replace('/(\s+)?\\\t(\s+)?/', '', $json);

謝謝:)它的工作。 – piotr

最後一個不會刪除所有空格。例如，對於值爲'142.59'的值，它會刪除空格和製表符。是否有可能刪除空格標籤和sapce？ – piotr

它與您的示例數據一起工作，但我更新了模式。 – AbraCadaver

function clear_array(&$arr) 
{ 
     array_walk($arr,function (&$value,$key) 
     { 
       if(gettype($value)=='array') 
         clear_array($value); 

       else if(gettype($value)=='string'){ 
         $value= preg_replace('/[\s]/', '', $value); 
       } 
     }); 
}

傳遞您的數組，它將從值中移除所有空格。

我已經將我的數據數組傳遞給了這個函數，但它完全刪除了它。當我回應結果時，我得到了'null'。 '$ arrData = clear_array（$ arrData）; $ jsonEncodedData = json_encode（$ arrData）; echo $ jsonEncodedData;' – piotr

我用你的json輸入作爲一個測試，通過下面一行'$ arr = json_decode（$ x，$ assoc = true）; clear_array（$ arr）;' 它很好用 –

Works，thanks :) – piotr
