我正在开发一个测试网站,提供搜索信息等房地产信息。除了房屋的图像外,还有通过目录访问引入的描述。除了“Description:”行之外,我的所有行都正常工作。在文本文件中,每个类别都按行分隔,但“描述:”类别在标题行之后运行,在多行之前运行直到文件末尾。我使用连接的fgets获取信息,但在我的结果中输出正确显示完整的房屋信息,包括“描述:”行,但在每个后续结果上,房屋信息重复之前打印的内容,然后是其余的下一个文件。如果我摆脱了连接而只是做一个常规的:
$pos = stripos($line, 'Description:');
if($pos !== false)
{
$description = substr($line, 12);
$description = trim($description);
}
然后我最终只得到“描述:”打印而没有描述部分的文字。
这是导入文本文件的示例:
城市:OceanCove
价格:950,000美元
卧室:5
浴场:3
素材:3000平方英尺
房地产经纪人:Shirley Urkiddeng
Grabber:梦幻般的家,有美妙的景色!
说明:
你永远不会厌倦观看日落
从客厅沙发或日出
从您的后门廊俯瞰
华丽的珊瑚峡谷。千载难逢的
机会!
这是我的代码(在“描述”部分中,我做了一些评论其他试验:

答案 0 :(得分:1)
由于Description
可能包含多行,因此您必须遍历这些行,直到完成Description
字段为止。如果您在同一个文件中有多个项目,则可能需要搜索下一个City
才能进行纾困。类似的东西:
if($descriptionFlag=='Y') {
while ($line = fgets($handle, 8192)) {
$line = trim($line);
if($line === 'City')
break;
$description = $description . " " . $line;
}
$description = $description . "<br />\n";
}

尝试
if($descriptionFlag=='Y') {
while ($line = fgets($handle, 8192)) {
$line = trim($line);
if(substr($line,0,4) === 'City')
break;
$description = $description . " " . $line;
}
$description = $description . "<br />\n";
}
