我收到此 PHP 代码的语法错误
syntax error, unexpected T_STRING
它说第 2 行，即包含行：
<?php
include 'config.inc.php';
// initialization
$photo_upload_fields = '';
$counter = 1;
// If we want more fields, then use, preupload.php?number_of_fields=20
$number_of_fields = (isset($_GET['number_of_fields'])) ?
(int)($_GET['number_of_fields']) : 5;
// Firstly Lets build the Category List
$result = mysql_query('SELECT category_id,category_name FROM gallery_category');
while($row = mysql_fetch_array($result)) {
$photo_category_list .= <<<__HTML_END
<option value="$row[0]">$row[1]</option>\n
__HTML_END;
}
mysql_free_result( $result );
// Lets build the Image Uploading fields
while($counter <= $number_of_fields) {
$photo_upload_fields .= <<<__HTML_END
<tr><td>
Photo {$counter}:
<input name="photo_filename[]"
type="file" />
</td></tr>
<tr><td>
Caption:
<textarea name="photo_caption[]" cols="30"
rows="1"></textarea>
</td></tr>
__HTML_END;
$counter++;
}
// Final Output
echo <<<__HTML_END
<html>
<head>
<title>Lets upload Photos</title>
</head>
<body>
<form enctype="multipart/form-data"
action="upload.php" method="post"
name="upload_form">
<table width="90%" border="0"
align="center" style="width: 90%;">
<tr><td>
Select Category
<select name="category">
$photo_category_list
</select>
</td></tr>
<! - Insert the image fields here -->
$photo_upload_fields
<tr><td>
<input type="submit" name="submit"
value="Add Photos" />
</td></tr>
</table>
</form>
</body>
</html>
__HTML_END;
?>
我的包含文件如下所示：
<?php
$mysql_link = mysql_connect("localhost","user","password");
mysql_select_db("db_name") or die("Could not select database");
$images_dir = "photos";
?>
解决方案：
我在代码中隐藏了不可见的 unicode 字符，导致 PHP 解析器抱怨上述语法错误。
