fread — Reads from a file.


string fread(file_handle, bytes);
resource file_handle: File handle
int bytes: Number of bytes to read




Reads from a file. The bytes argument allows for a set number of bytes to be read, although reading stops if EOF is reached first. The function is binary-safe, allowing it to safely read binary data (such as images or program executables), as well as character data. The data read is returned as a string.


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: Doesn't work correctly with sockets, Red Hat Linux 6.

3.0.7: Crashes when reading local file on Red Hat Linux 6, kernel 2.2.7.

3.0.9: Delays/hangs on Linux Red Hat 5.2 when reading from sockets.


Example 325. Read from a file

$file = "test.txt";

$fh = fopen($file, "r");
$string = fread($fh, 1024);

echo ("$string");
