fgets

Popis

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:

P°φklad 1. Reading a file line by line $fd = fopen ("/tmp/inputfile.txt", "r"); while (!feof ($fd)) { $buffer = fgets($fd, 4096); echo $buffer; } fclose ($fd);
