Read line and change the line that not consist of certain words and not end with dot
- by igo
I wanna read some text files in a folder line by line. for example of 1 txt :
Fast and Effective Text Mining Using Linear-time Document Clustering
Bjornar Larsen WORD2 Chinatsu Aone
SRA International AK, Inc.
4300 Fair Lakes Cow-l Fairfax, VA 22033
{bjornar-larsen, WORD1
I wanna remove line that does not contain of words = word, word2, word3, and does not end with dot .
so. from the example, the result will be :
Bjornar Larsen WORD2 Chinatsu Aone
SRA International, Inc.
{bjornar-larsen, WORD1
I am confused, hw to remove the line? it that possible? or can we replace them with a space?
here's the code :
$url = glob($savePath.'*.txt');
foreach ($url as $file => $files) {
$handle = fopen($files, "r") or die ('can not open file');
$ori_content= file_get_contents($files);
foreach(preg_split("/((\r?\n)|(\r\n?))/", $ori_content) as $buffer){
$pos1 = stripos($buffer, $word1);
$pos2 = stripos($buffer, $word2);
$pos3 = stripos($buffer, $word3);
$last = $str[strlen($buffer)-1];//read the las character
if (true !== $pos1 OR true !== $pos2 OR true !==$pos3 && $last != '.'){
//how to remove
}
}
}
please help me, thank you so much :)
