PHP Read text files

Reading files is just as easy as writing them.

<?php
$str = file_get_contents("myfile.txt");
echo $str;
?>

People might not like it, but it works and is super easy.

PHP Write to file

Writing to files with PHP is a snap, it's super easy, like most everything about PHP. First, open a file handle (or stream), write to the stream, then close it. ALWAYS CLOSE.

<?php
$fh = fopen("myfile.txt","w");
fwrite($fh,"hello world\n");
fclose($fh);
?>

When you write to the file, try to write only once if you can. If you need to store data, build it up then write it to file, like below.

<?php
$data = array("My data","hello","world","goes","here","write","to","file");
$str = "";
for($i=0;$i<sizeof($data);$i++)
{
    $str .= $data[$i]."\r\n";
}

$fh = fopen("myfile.txt","w");
fwrite($fh,$str);
fclose($fh);
?>
