Problems saving XAMPP database

I'm having a lot of trouble with my xampp , some time I've been trying to add anything to the mysql database but I'm not successful in my attempts.

In% of PHP, the following lines are described:

  

[Sat Feb 13 01: 31: 07.052501 2016] [mpm_winnt: notice] [pid 2604: tid 468] AH00455: Apache / 2.4.18 (Win32) OpenSSL / 1.0.2e PHP / 7.0.1 configured - resuming normal operations

I'm making a simple error.log as follows:

try {
    $campos = array();
    $campos[':TXT_NOMEX_BANNE'] = $targetFile;
    $campos[':pesso'] = '1'; //$suc->$COD_IDENT_USUAR();

    $sql = "INSERT INTO tbl_banner ('TXT_NOMEX_BANNE', 'COD_ULTIM_ATUAL', 'DAT_ULTIM_ATUAL') VALUES (:TXT_NOMEX_BANNE, :pesso, now())";
    $conexao = new ConexaoDatabase();
    $conexao->save($sql, $campos);

    move_uploaded_file($tempFile, $targetFile);
} catch (Exception $e) {

    die('ERRO AO ATUALIZAR BANCO DE DADOS');
    error_log($e->getMessage());
}

My folder structure is as follows:

|includes
|--conexao.php
|--suc_validacao.php
|paginas
|--upload.php

And I'm giving an include as follows:

include '../includes/suc_validacao.php';
include '../includes/conexao.php';

In insert I have a conexao.php function, and it calls another function. Both described below:

   public function save($sql, array $data) {

        $con = self::getConnection();

        $stmt = $con->prepare($sql);

        $this->execute($stmt, $data);

        if ($stmt->rowCount()) {
            return true;
        } else {
            return false;
        }
    }
    public function execute(PDOStatement $stmt, array $data = null) {
        try {
            if (isset($data)) {
                $stmt->execute($data);
            } else {
                $stmt->execute();
            }
            return true;
        } catch (PDOException $exc) {
            if (isset($_SESSION['suc'])) {
            return false;
        }
    }

If you have anything else to add, but I tried to do a lot of things, including reinstalling save , redo xampp , and more. Nothing worked, I already looked for something on the internet about the error, but I also did not find anything about it.

I would love help solving this problem.
