Warning: session_start(): Failed to read session data: user (path:)

[tennom]

I couldn't make this code work with both the latest stable PHP7.2.2 and PHP7.1.X.

I also had the --enable-fpm with compilations. It showed this error Warning: session_start(): Failed to read session data: user (path:).
I also tried to override default session manager with implements \SessionHandlerInterface which returned same error. Then I started doubting some compatibility issues of 7.2 and 7.1 with session_set_save_handler, but can't find any proof and not much time dig in as of now.

I could make it work with PHP7.0.X. builds with no problem!

Check this

replace

	public function _read($id){
		// Set query
		$this->db->query('SELECT data FROM sessions WHERE id = :id');
		// Bind the Id
		$this->db->bind(':id', $id);
		// Attempt execution
		// If successful
		if($this->db->execute()){
		// Save returned row
		$row = $this->db->single();
		// Return the data
		return $row['data'];
		}else{
		// Return an empty string
		return '';
		}
	}

with this

	public function _read($id){
		// Set query
		$this->db->query('SELECT data FROM sessions WHERE id = :id');
		// Bind the Id
		$this->db->bind(':id', $id);
		// Attempt execution
		// If successful
		if($this->db->execute()){
			// Save returned row
			$row = $this->db->single();
			// Return the data
			if (is_null($row['data'])) {
				return '';
			}
			return $row['data'];
		}
	}

works with php 7.1

Thanks for the solution. I learned that php 7.1 and above strictly requires the session read to return a string and not even a null value. That's why the error was raised. This code also raised an error when using registration-ID function. Because it follows a different action cycle in 7.1 and above I suspect, like read->close->read->write... I will post my code when i return to that problem soon.

Hi I'm having the same issue with migrating from PHP 7.0 to 7.1

I'm trying to find which file has the above stated code to update the function _read. Sorry I'm new.

I used a different approach. I don't think wintstar's code solves the issue.

Hi. May you please share with me your solution? I'm finding it terribly difficult to migrate php 7.0 to 7.1 thanks.
