### Description
The following code:
```php
<?php
class Loader {
public $context;
private $position;
private $data;
public function stream_open($path, $mode, $options, &$opened_path) {
$this->data = '<' . "?php \n\"\";ll l\n ?" .
'>';
$this->position = 0;
return true;
}
function stream_read($count) {
$ret = substr($this->data, $this->position, $count);
$this->position += strlen($ret);
return $ret;
}
function stream_eof() {
return $this->position >= strlen($this->data);
}
function stream_flush() {
var_dump("flush!");
}
function stream_close() {
@unlink(__DIR__."/bug38779.txt");
var_dump("close!");
}
}
stream_wrapper_register('Loader', 'Loader');
$fp = fopen ('Loader://qqq.php', 'r');
$filename = __DIR__."/bug38779.txt";
$fp1 = fopen($filename, "w");
fwrite($fp1, "<"."?php blah blah?".">");
fclose($fp1);
include $filename;
```
Resulted in this output:
```
Parse error: syntax error, unexpected identifier "blah" in /tmp/bug38779.txt on line 1
string(6) "close!"
```
The following code:
```php
<?php
function foo()
{
class Loader {
public $context;
private $position;
private $data;
public function stream_open($path, $mode, $options, &$opened_path) {
$this->data = '<' . "?php \n\"\";ll l\n ?" .
'>';
$this->position = 0;
return true;
}
function stream_read($count) {
$ret = substr($this->data, $this->position, $count);
$this->position += strlen($ret);
return $ret;
}
function stream_eof() {
return $this->position >= strlen($this->data);
}
function stream_flush() {
var_dump("flush!");
}
function stream_close() {
@unlink(__DIR__."/bug38779.txt");
var_dump("close!");
}
}
stream_wrapper_register('Loader', 'Loader');
$fp = fopen ('Loader://qqq.php', 'r');
