Description
string fgets (int fp, int length)
Returns a string of up to length - 1 bytes read from the file
pointed to by fp. Reading ends when length - 1 bytes have been
read, on a newline (which is included in the return value), or on
EOF (whichever comes first).
If an error occurs, returns false.
Common Pitfalls:
People used to the 'C' semantics of fgets should note the
difference in how EOF is returned.
The file pointer must be valid, and must point to a file
successfully opened by fopen(),
popen(), or
fsockopen().
A simple example follows:
Esempio 1. Reading a file line by line
$fd = fopen ("/tmp/inputfile.txt", "r");
while (!feof ($fd)) {
$buffer = fgets($fd, 4096);
echo $buffer;
}
fclose ($fd);
