PHP突然停止工作？

Question

这是我们目前正在进行网站设计/迁移（MAJOR HEADACHES）的交易，从直接的PHP/HTML网站到基于Drupal的网站。我们有我们的家庭人员（也就是我）在做事情，然后我们有设计人员，他们也有第三方做事情。几个星期前，我用我们旧网站的一些代码创建了一个view - 查看drupal，它扫描一个目录并列出目录中关于我们工作人员报告的所有内容。自那以后我没有碰过它，并且它一直工作得很好，因为其他6页以同样的方式完成。周四下午，该页面突然停止工作，只会呈现空白页面。我没有触及它，并且尽可能接近我所知道的其他人。我将它与其他页面进行了比较，但我看不到任何错误。我错过了什么吗？或者这是一个Drupal问题？

基本PHP：" -quoted字符串不能在其中" -quotes除非他们逃脱：

print "<a href=\"/staff-reports/$year/$reports[$i] \ "> "; 
                 ^^ 

你baskslash是逃避的空间，而不是"字符。
