1 php File System 1.1 php file read

The function that the file reads is file_get_contents, the entire file can be read into a string

$content = file_get_constents(‘./test.test‘);//不知道为什么我的电脑里面必须要用绝对路径

You can also control the start point and the length of the read content

PHP also provides a method similar to the C language operation file, using methods such as Fopen,fgets,fread, fgets can read a line from the file pointer, Freads can read a string of a specified length.

$fp = fopen(‘./text.txt‘, ‘rb‘);while(!feof($fp)) {    echo fgets($fp); //读取一行}fclose($fp);

$fp = fopen(‘./text.txt‘, ‘rb‘);$contents = ‘‘;while(!feof($fp)) {    $contents .= fread($fp, 4096); //一次读取4096个字符}fclose($fp);
