How to read files line by line in PHP

Background

[wp_ad_camp_1]

PHP is not as bad as other people would think. Sometimes it is easier to do things in PHP than in, say, Java. Consider reading a text file line by line and parsing each pipe-delimited line.

Hardware Environment

n/a

Software Environment

Windows 7 Professional SP1
PHP 5.5.9 / Zend Engine v2.5.0

PHP Codes

That’s less than 10 lines. Way less codes than in Java.

$file = fopen('data.txt', 'r');
while(($line = fgets($file)) != false)
{
    $fields = explode("|", $line);
    foreach($fields as $value)
    {
        echo $value . "\n";
    }

}
fclose($file);
