In this I would like to achieve the opposite, there are no errors, I want to generate them. I'm studying the use of PHP's ob_* functions. I found this code to understand the concepts, and it is supposed to throw an error, since I understand that once an output is sent, the headers can no longer be modified, or set the sessions or cookies. Can someone explain to me why everything flows smoothly?

  <?php
    //ob_start();

echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">';

?>
<html>

<head>
    <title>Página procesada con buffer de salida</title>
</head>

<body>
    Esta es mi página!!!
</body>

</html>
<?php

setcookie("nombre", "john");
//ob_end_flush(); 
?>

I'm already desperate thinking about why I can't get any results from the sql subqueries in LARAVEL. this is my code

$Sql= "SELECT cuenta_judicial.IDNRO,demandas2.CI, 
                (SELECT TITULAR from demandado 
                where demandado.CI=demandas2.CI 
                OR (demandado.CI is null 
                AND demandado.IDNRO=demandas2.CI) ) AS TITULAR,
            demandas2.DEMANDA, 
            demandas2.CTA_BANCO, 
            (SELECT sum( mov_cta_judicial.IMPORTE) 
            from mov_cta_judicial 
            where mov_cta_judicial.CTA_JUDICIAL= cuenta_judicial.IDNRO and mov_cta_judicial.TIPO_MOVI='E' 
                AND mov_cta_judicial.TIPO_EXT='C') as CAPITAL,
            (SELECT sum( mov_cta_judicial.IMPORTE) from mov_cta_judicial where mov_cta_judicial.CTA_JUDICIAL= cuenta_judicial.IDNRO and mov_cta_judicial.TIPO_MOVI='E' and mov_cta_judicial.TIPO_EXT='L') as LIQUIDACION ,
            (SELECT sum( mov_cta_judicial.IMPORTE) from mov_cta_judicial where mov_cta_judicial.CTA_JUDICIAL= cuenta_judicial.IDNRO and mov_cta_judicial.TIPO_MOVI='D') AS DEPOSITO 
            from cuenta_judicial,demandas2 
            WHERE demandas2.CTA_BANCO=cuenta_judicial.CTA_JUDICI";

 
 $lista= DB::select($Sql);

I execute that same query in PHPmyAdmin and it returns all the records. But when wanting to do it in LARAVEL NOTHING. Does anyone know why? what should I do?

NO problems when I run it like this: enter image description here

But in laravel nothing

The thing is this, it turns out that when I use codeigniter's helper: "form", the url it generates for the action property has something strange at the beginning, this [::1]. What does that mean? What should I configure to display the IP correctly, in my case 127.0.0.1

 <?php echo form_open('cliente/get'); ?>
            <h3>Buscar</h3>
            <input type="text"  id="ci-busq" />
            <button type="button" onclick="buscarCliente(event)"> Ok</button>
    </form>

Seeing in the browser console, I verify that the generated url is like this: enter image description here

<form enctype="multipart/form-data" action="eje02.php" method="post">

 <input type="hidden" name="MAX_FILE_SIZE" value="2000000"/> 


Send this file: <input name="userfile" type="file"  value="" />
<input type="submit" value="Send File">
</form>

The PHP file:

if(  is_uploaded_file(  $_FILES['userfile']['tmp_name'])   ){
    print "<h1> Archivo subido!</h1>"; 

}else{
    /** Hubo un error */
    $codigo_de_error= $_FILES['userfile']['error'];
    $mensaje="";

    switch(  $codigo_de_error){
    case UPLOAD_ERR_OK: //valor 0
        $mensaje="Archivo subido correctamente";
        break;
    case UPLOAD_ERR_INI_SIZE:
        $mensaje="El fichero subido excede la directiva upload_max_size de php.ini";
        break;
    case UPLOAD_ERR_FORM_SIZE:
        $tama= ( (int)$_FILES['userfile']['size']  )/1024;

        $mensaje="El fichero subido excede la directiva MAX_FILE_SIZE especificada 
        en el formulario,  Size del archivo es $tama";
        break;
    case UPLOAD_ERR_PARTIAL:
        $mensaje="Archivo parcialmente subido";
        break;
    case UPLOAD_ERR_NO_FILE:
        $mensaje="No se subio ningun fichero";
        break;
    case UPLOAD_ERR_NO_TMP_DIR:
        $mensaje="Falta la carpeta temporal. ( desde php 5.0.3)";
        break;
    case UPLOAD_ERR_CANT_WRITE:
        $mensaje="No se pudo escribir el fichero en el disco (desde php 5.1.0)";
        break;
        case UPLOAD_ERR_EXTENSION:
        $mensaje="Una extension de PHP detuvo la subida del fichero (desde php 5.2.0)";
        break;
    }
    print "Codigo {$_FILES['userfile']['error']}  ,  $mensaje";
}

I only want to upload the file and no more, but I have seen in the php.ini that the maximum upload size is 2M, so I have put 2000000 for the MAX_FILE_SIZE, and it still generates error 2. Any suggestions?

I already tried with the directive init_set, the file index.phpis set to ENVIRONMENT=DEVELOPMENT, I have searched a lot on the web and nothing has worked for me.

I don't have access to server configuration files, that's why I need to activate the messages, because debugging is complicated like that.

Solution This was the modification I made in the index.php

define('ENVIRONMENT',   'development');
/**** ERROR REPORTING
Different environments will require different levels of error reporting.
By default development will show errors but testing and live will hide them.*/

switch (ENVIRONMENT)
{
case 'development':  
    error_reporting( E_ALL );
    ini_set('display_errors', 1 );
break;

case 'testing':
case 'production':
    ini_set('display_errors', 0);
    if (version_compare(PHP_VERSION, '5.3', '>='))
    {
        error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_USER_NOTICE & ~E_USER_DEPRECATED);
    }
    else
    {
        error_reporting(E_ALL & ~E_NOTICE & ~E_STRICT & ~E_USER_NOTICE);
    }
break;

default:
    header('HTTP/1.1 503 Service Unavailable.', TRUE, 503);
    echo 'The application environment is not set correctly.';
    exit(1); // EXIT_ERROR
}
