Answer 1

function get_words($sentence, $count = 10) {
preg_match("/(?:\w+(?:\W+|$)){0,$count}/", $sentence, $matches);
return $matches[0];
}
$file = fopen("quiz3.txt","r") or die("Unable to open file!");
$line = fgets($file);
$convertedLine = get_words($line );
$sql = "INSERT INTO quiz3 (FromFile) VALUES ('".$convertedLine ."')";

Answer 2

Not sure if your data contains comma, or other symbols.
This might be quick solution, and it also works with CJK words.
<?php
function cut_words($source, $number_take){
$result = "";
$wc = 0;
$source = str_replace(" ", " ", $source); // Simple sanity
$string = explode(" ", $source);
while ($wc < $number_take){
if(isset($string[$wc])){ // Prevent index out of bound.
$result .= $string[$wc];
if($wc < $number_take) {
$result .= " ";
}
$wc++;
} else {
break;
}
}
$result = trim($result);
return $result;
}
$line = cut_words($line, 10);
?>
