php - 有关 if 条件句错误

问题描述

问 题

写了一个kirby CMS的API，发现不停报错。
先上代码：

<?php if(!defined('KIRBY')) die('Direct access is not allowed');
if (isset($_GET['get']) || isset($_GET['transshipment']))
{
  if (isset($_GET['get']) && !isset($_GET['transshipment']))
  {
    if ($_GET['get'] == 'title')
    {
      if (null !== $page->title())
      {
      echo "E303";//no title setted
      die();
      }
    echo $page->text()->title();
    die();
    }
    elseif ($_GET['get'] == 'content')
   {
      if (null !== $page->content())
      {
      echo "E303";//no content setted
      die();
      }
    echo html($site->title()->content());
    die();
    }
    elseif ($_GET['get'] == 'author')
    {
      if (null !== $page->author())
      {
      echo "E303";//no author setted
      die();
      }
    echo $page->author();
    die();
    }
    elseif ($_GET['get'] == 'dates')
    {
      if (null !== $page->dates())
      {
      echo "E303";//no dates setted
      die();
      }
    echo $page->dates();
    die();
    }
    elseif ($_GET['get'] == 'introduction')
    {
      if (null !== $page->introduction())
      {
      echo "E303";//no introduction setted
      die();
      }
    echo $page->introduction();
    die();
    }
    else
    {
    echo "E301";//error API information getting(error after "=")
    die();
    }
  }
  elseif (!isset($_GET['get']) && isset($_GET['transshipment']))
  {
  echo "E302";//error API information getting(error before "=")
  die();
  }
  elseif (isset($_GET['get']) && isset($_GET['transshipment']))
  {
  echo "E304";//error API information getting(getting value override)
  die();
  }
  else
  {
  }
}
else
{
}
?>

保存后在尝试打开时发现报错：

[18-Nov-2016 12:02:14 UTC] PHP Parse error: syntax error, unexpected 'if' (T_IF) in /home/sunhbjaq/public_html/site/templates/work.php on line 2

请问这里哪里有语法错误，谢谢！
（新手，请耐心回答，谢谢。）

解决方案

楼上所言甚是。

你要把第一行分号后面的东西（隐藏字符）去掉。

另外要记得，PHP说 第X行出现错误 的时候，一定要从 X-1 行开始找错。

<?php if(!defined('KIRBY')) die('Direct access is not allowed');
if (isset($_GET['get']) || isset($_GET['transshipment']))
{
  if (isset($_GET['get']) && !isset($_GET['transshipment']))
  {
    if ($_GET['get'] == 'title')
    {
      if (null !== $page->title())
      {
      echo "E303";//no title setted
      die();
      }
    echo $page->text()->title();
    die();
    }
    elseif ($_GET['get'] == 'content')
   {
      if (null !== $page->content())
      {
      echo "E303";//no content setted
      die();
      }
    echo html($site->title()->content());
    die();
    }
    elseif ($_GET['get'] == 'author')
    {
      if (null !== $page->author())
      {
      echo "E303";//no author setted
      die();
      }
    echo $page->author();
    die();
    }
    elseif ($_GET['get'] == 'dates')
    {
      if (null !== $page->dates())
      {
      echo "E303";//no dates setted
      die();
      }
    echo $page->dates();
    die();
    }
    elseif ($_GET['get'] == 'introduction')
    {
      if (null !== $page->introduction())
      {
      echo "E303";//no introduction setted
      die();
      }
    echo $page->introduction();
    die();
    }
    else
    {
    echo "E301";//error API information getting(error after "=")
    die();
    }
  }
  elseif (!isset($_GET['get']) && isset($_GET['transshipment']))
  {
  echo "E302";//error API information getting(error before "=")
  die();
  }
  elseif (isset($_GET['get']) && isset($_GET['transshipment']))
  {
  echo "E304";//error API information getting(getting value override)
  die();
  }
  else
  {
  }
}
else
{
}
?>
