The fgets length is like this: It's the number of bytes read from a
file OR up to a new line character. Which ever comes first. It's as
simple as that.
Try this:
<?
$file = "filename.txt"; // Name of file
$fp = fopen($file, "r");
if(!$fp){
echo "Couldn't open file for reading.";
}
else{
$i = 1; // used for name of inputs
while($buffer = fgets($fp, 18976) ){ //18796 is what I use. Use a
larger number if your lines are larger.
print "<input type='text' name='line[$i]' value='" . $buffer .
"'><br>";
$i++;
}
}
fclose($fp);
?>
That's what gets displayed to this user and this is how we would rewrite
the file:
<?
$file = "filename.txt";
$fp = fopen($file, "w");
if(!$fp){
print "Couldn't open the file for writing";
}
else{
for($x = 1; $x <= count($line); $x++){
fputs($fp, $line[$x], strlen($line[$x]);
}
}
fclose($fp);
?>
I hope this helps.
