I think my problem is happening because my line is so long that its only showing the first one, is there a way to change the output into seperate even fields? Meh, I don't even think thats the real problem either, I can get it to work out of my program but not inside it. It never displays the 3 lines of data that it says that it has with -c.
--- It seems to me that within my code, It only prints the last line of the file that contains what ever I am grepping, any idea? it counts a certain number but displays the LAST line that it counts!

How come grep testfile1 won't find anything in testfile1 (even though the characters sd are there in great quantity), but grep '' testfile1 will find plenty?
Do the single quotes prevent the shell from interpreting the testfile1 is interpreted as: grep *test whether or not characters sd exist*... (5 Replies)

LEARN ABOUT PHP
fgets
FGETS(3) 1 FGETS(3)fgets - Gets line from file pointerSYNOPSIS
string fgets (resource $handle, [int $length])
DESCRIPTION
Gets a line from file pointer.
PARAMETERS
o $handle
-The file pointer must be valid, and must point to a file successfully opened by fopen(3) or fsockopen(3) (and not yet closed by
fclose(3)).
o $length
- Reading ends when $length - 1 bytes have been read, or a newline (which is included in the return value), or an EOF (whichever
comes first). If no length is specified, it will keep reading from the stream until it reaches the end of the line.
Note
Until PHP 4.3.0, omitting it would assume 1024 as the line length. If the majority of the lines in the file are all larger
than 8KB, it is more resource efficient for your script to specify the maximum line length.
RETURN VALUES
Returns a string of up to $length - 1 bytes read from the file pointed to by $handle. If there is no more data to read in the file
pointer, then FALSE is returned.
If an error occurs, FALSE is returned.
CHANGELOG
+--------+-----------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+-----------------------------+
| 4.3.0 | |
| | |
| | fgets(3) is now binary safe |
| | |
+--------+-----------------------------+
EXAMPLES
Example #1
Reading a file line by line
<?php
$handle = @fopen("/tmp/inputfile.txt", "r");
if ($handle) {
while (($buffer = fgets($handle, 4096)) !== false) {
echo $buffer;
}
if (!feof($handle)) {
echo "Error: unexpected fgets() fail
";
}
fclose($handle);
}
?>
NOTES
Note
If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the
auto_detect_line_endings run-time configuration option may help resolve the problem.
Note
People used to the 'C' semantics of fgets(3) should note the difference in how EOF is returned.
