Question

我需要有关如何在我的php脚本中添加“if else”语句的帮助，我需要new_license_issued_date字段为null，如果为null，而不是01/01/1970，就像它正在通过... 。请帮忙！谢谢

 <table cellpadding='0' cellspacing='0' border='0' class='display' id='table' width='100%'>

    <tbody>
    <?php
    //display the results 
    while($row = mssql_fetch_array($result))

Answer 1

使用三元运算符。

<td>". (is_null($row['new_license_issued_date']) 
               ? "NULL" 
               : date('d-M-Y', strtotime($row['new_license_issued_date']))) ."</td>

Answer 2

你试过了吗？

($row['new_license_issue_date'] ? date('d-M-Y', strtotime($row['new_license_issue_date'])) : '&nbsp');

Answer 3

或者如果您更容易使用它：

echo "<td>";

   if($row['new_license_issued_date'] !== NULL){
      echo date('d-M-Y', strtotime($row['new_license_issued_date']));
   } else {
      echo "&nbsp;";
   }

echo "</td>";

将php if else添加到html代码中
