我需要单独进行每个特定的分析。我认为最好的方法是用新的空行分开此文件(有人有其他方法(。有人对如何执行此操作有任何想法吗？我正在使用PHP。此文件来自Masc语料库。
谢谢。
我实际上以以下方式完成了它：
$newfile= file("textfile.txt");
$temp_str='';
$parses=array();
foreach ($newfile as $line) {
$temp=trim($line);
if(strlen($temp)>0){
$temp_str.=$temp;
}
else{
array_push($parses, $temp_str);
$temp_str='';
}
}
