boolean rewind(integer file_handle)

The rewind function moves PHP's internal file pointer back to the beginning of the file.
This is the same as using fseek to move to position zero.

<?
/*
* print a file, then print the first line again
/

// open a local file
$myFile = fopen("data.txt", "r");

while(!feof($myFile))
{
// read a line from the file
$myLine = fgetss($myFile, 255);
print("$myLine
\n");
}
rewind($myFile);
$myLine = fgetss($myFile, 255);
print("$myLine
\n");

// close the file
fclose($myFile);
?>

boolean rewinddir(integer handle)

The rewinddir function resets PHP's internal pointer to the beginning of a directory
listing. It returns TRUE unless an error occurs, in which case it returns FALSE. The handle
is an integer returned by opendir.

<?
/*
* print the current directory in a table
/
print("<TABLE BORDER=\"1\">\n");

// open directory
$myDirectory = opendir(".");

print("\n");
print("Filename\n");

// get each entry
while($entryName = readdir($myDirectory))
{
print("$entryName\n");
}
