    <?php

$counter=0;
$content=file("linux.words");

foreach ($content as $line)
{

$words = explode(' ', $line); // Split a line by the delimiter "spacer"
for ($i=0; $i < count($words) ; $i++) {
    if($words[$i][0]=="a") { // First letter of each word
        echo $words[$i]."<br />";
        $counter++;
    }
}

}
echo "counter=".$counter."<br>";

?>
