How to register a stream wrapper
<?php
$existed = in_array("var", stream_get_wrappers());
if ($existed) {
stream_wrapper_unregister("var");
}
stream_wrapper_register("var", "VariableStream");
$myvar = "";
$fp = fopen("var://myvar", "r+");
fwrite($fp, "line1
");
fwrite($fp, "line2
");
fwrite($fp, "line3
");
rewind($fp);
while (!feof($fp)) {
echo fgets($fp);
