 question how can make sentence @ 1 line in source code too. thanks.

here piece of code don´t have here randomly loading data, made illustration in cycle.

$file = fopen("test.txt", "r"); $data = array(); while (($buffer = fgets($file)) !== false) {   $data[] = $buffer; }  $sentence = '';  ($i=0;$i<10;$i++){   $sentence = $sentence . $data[$i]; }

use trim function filter new line characters. in code use:

$data[] = trim($buffer);
