读取文件保留换行符和空格

Question

I'm writing a PHP script which stores the values in the file in an array. I want newlines and spaces to be preserved.

The text file looks like below:

abc

pqr

xyz

What I thought is to use cat Linux command to read the file and then direct it's value in an array.

This is what I tried:

$input = '/var/www/oj/1.in';
$array = system(cat $input);

That didn't work. Any ideas?

Answer 1

Try the function that is used for this:

$array = file($input);
print_r($array);

But since you don't actually want an array as stated in the question, try:

$output = file_get_contents($input);

Or to skip the empty lines:

$output = implode(file($input, FILE_SKIP_EMPTY_LINES));
