我想從本地文件讀取前200個字符,但是,我的代碼正在讀取我的文本文件的所有內容。如何在php中限制文本長度'file_get_contents'並提供'Read more'鏈接

<?php 
    $connection= new mysqli($DB_host,$DB_user,$DB_pass,$DB_name); 
    $query = mysqli_query($connection,"SELECT * FROM new_record ORDER BY id"); 
    while ($row = mysqli_fetch_array($query)) { 
     $fileName = $row['name']; 
     $fileContents = file_get_contents("txt/$fileName"); 
     echo ("$fileContents"); 
    } 
?> 
+0

你可以嘗試:echo substr($ fileContens,0,200); –
