The difference between file_get_contents() and file_PHP tutorial

aaaaaa

bbbbbb

bbbbccc

Okay, just these three lines, now let’s look at the operation method of file_get_contents.

$content = file_get_content('a,txt');

$temp =str_replace(chr(13),'|',$content);
 
$arr =explode('|',$temp);

It’s not much more than just three lines, so let’s take a look at the file function.

$content = file('a.txt');
