Question

新手技术难度在这里。希望我能清楚地解释清楚。在我的数据库中，我有snFreq，snFreq2，snFreqIV，snFreqTube，snFreqTrach，snFreqCath，snFreqWound和snFreqOstomy。如果数据存在，我写了一个isset来检查每一列，然后使用预设文本创建一个变量。在所有检查点之后，我想将其包含在一个短语中，但不希望包含“0”数据。由于某种原因，我的输出仍然显示多个带空白数据的逗号。这是一个示例输出： SN频率/持续时间：QD X 60天+ 2次PRN访问IV并发症，管饲喂复杂，,,,＆lt; =有额外的逗号？在我的DB中： snFreq = QD X 60天，snFreq2 = 1，snFreqIV = 1，snFreqTube = 1，其余为空。

    if(isset($rowPlanOfCare['snFreq'])){$snFreq = "SN FREQUENCY/DURATION: " . $rowPlanOfCare['snFreq'];}
    if(isset($rowPlanOfCare['snFreq2'])){$snFreq2 = " + 2 PRN VISITS FOR ";}
    if(isset($rowPlanOfCare['snFreqIV'])){$snFreqIV = "IV COMPLICATIONS";}
    if(isset($rowPlanOfCare['snFreqTube'])){$snFreqTube = "TUBE FEEDING COMPLICATIONS";}
    if(isset($rowPlanOfCare['snFreqTrach'])){$snFreqTrach = "TRACHEOSTOMY CARE COMPLICATIONS";}
    if(isset($rowPlanOfCare['snFreqCath'])){$snFreqCath = "CATHETER CARE COMPLICATIONS";}
    if(isset($rowPlanOfCare['snFreqWound'])){$snFreqWound = "WOUND CARE COMPLICATIONS";}
    if(isset($rowPlanOfCare['snFreqOstomy'])){$snFreqOstomy = "OSTOMY CARE COMPLICATIONS";}
    $snFrequency = $snFreq . $snFreq2 . implode(", ",array($snFreqIV, $snFreqTube, $snFreqTrach, $snFreqCath, $snFreqWound, $snFreqOstomy)) . "\n \n ";

最终输出应仅显示：SN频率/持续时间：QD X 60天+ 2个PRN访问IV并发症，管喂养并发症＆lt; ==没有其他逗号。

我希望你能帮我解决这个问题。提前致谢！：）

试试这个：

 $snFrequency = $snFreq . $snFreq2 . implode(", ",array_filter(array($snFreqIV, $snFreqTube, $snFreqTrach, $snFreqCath, $snFreqWound, $snFreqOstomy))) . "\n \n ";
