[PHP] Reading file to array

[vern]

I can read an entire file into an array using file(). Does anyone know how to read the a specified number of lines into an array instead of the entire file?

You could use file_get_contents to get the contents into a string and specifiy the max number of bytes, then use explode to get it into an array

or just get the array with file and and the loop through it x times and copy it to another array

or use fopen and fgets to get one line of the file at a time and loop until x lines

if you just want to read x number of lines then use something like

<?php
define('MAX_LINES', 100);
$fp = @fopen("/path/to/file");
$array_lines = array();
for ($i = 0; !feof($fp) && $i < MAX_LINES && $line = fgets($fp, 1024); $i++)
{
    $array[] = $line;
}
?>

This should work, I havent really tested it though, but the Code analyser in the Zend Development Environment didnt chuck up anything syntactically wrong with the code
