The fgets() functions is used to read a line from a file. Using this function we either read the entire line into a string or specify the number characters we like to read.
fgets ($handle, $length);
- $handle - the file pointer
- $length - number of bytes to read. If length is not specified it will read at the end of the line.
Reading entire line
<?php$fh = fopen("myfile.txt", "r");
$line = fgets($fh);
echo $line;
fclose($fh);
?>
Reading number of bytes
<?php$fh = fopen("myfile.txt", "r");
$str = fgets($fh, 64);
echo $str;
$line2 = fgets($fh, 64);
echo $str;
fclose($fh);
?>
Reading file line by line
<?php$fh = fopen("myfile.txt", "r");
while(true)
{
$line = fgets($fh);
if($line == null)break;
echo $line;
}
fclose($fh);
?>
Reading entire file at once
<?php$fh = fopen("myfile.txt", "r");
$file = file_get_contents("myfile.txt");
echo $file;
?>
