fgets
Name
fgets — Reads a line from a file.
Synopsis
string fgets(file_handle, bytes);
resource file_handle: File
handle
int bytes: Number of bytes
to read
Returns
Current line; FALSE on error
Description
fgets() is similar to fgetc() except that it
returns a line of text from the file pointer of a length
specified by the number of bytes. If a newline or EOF
occurs before the number of bytes specified is read,
fgets() returns the bytes read up to this point.
This can be extremely useful when reading and processing
lines of text from a file, pipe, or socket.
Because some of the filesystem functions to read/write
from files partially share the same code, one or more
of the bugs reported elsewhere may also apply to this
function.
3.0.6: Function not binary-safe.
3.0.11: Will not return when using non-blocking sockets
on Red Hat Linux 6, kernel 2.2.10.
3.0.11: Stops reading after HTTP header using socket
connection on Red Hat 5.1.
Example
Example 308. Dump a file
$fh = fopen("test.txt", "r");
while(!feof($fh))
{
$output = htmlspecialchars(fgets($fh, 1024));
echo ("$output<br>");
}
fclose($fh);
