Error 500 on php for loop

Question

I am making a little script that read emails from my inbox and save them in a mysql database.

I have a php that check emails and save them to DB, and break the FOR if it ran for more than 1 second, and I have an ajax script that call the php every time it stops.

so here is the ajax part:

<script type="text/javascript">
$(document).ready(function(e) {
chequearCorreo(1);
});

function chequearCorreo(inicio){
$.ajax({
  type: 'POST',
  url: 'inc/a.php',
  data: {mailInicio: inicio},
   success: function(data) {
       resultado = data.split("/");
       if(resultado[0]!=resultado[1]){
           //aun no termino
           chequearCorreo(resultado[0]);
       }
       $("body").html(data);

    },
    error: function(data){

    },
 contentType: "application/x-www-form-urlencoded;charset=ISO-8859-15",
 dataType: 'html'
});
}
</script>

and here is the php

session_start();
include 'coneccion-base-mails.php';

$crear_tabla_web =
'CREATE TABLE IF NOT EXISTS web  
(
id INT NOT NULL AUTO_INCREMENT,
uid int,
carpeta VARCHAR(200),
fecha DATETIME,
remitente VARCHAR(200),
destinatario VARCHAR(200),
cc VARCHAR(200),
cco VARCHAR(200),

flaged VARCHAR(20),
respondido VARCHAR(20),
reenviado VARCHAR(20),

)';
$mysqli->query($crear_tabla_web);

//FUNCION GUARDAR MAIL!!!

function guardarMail($uid,$carpeta,$fecha,$remitente,$destinatario,$cc,$cco,$asunto,$body,$leido,$flaged,$respondido,$reenviado){
global $mysqli;
//primero chequeamos que el mail no exista ya en la base
if ($result=$mysqli->query("SELECT * FROM web WHERE uid=".$uid."")){
    if( $result->num_rows == 0 ){
        //guardamos el post
        $fecha = strtotime($fecha);
        $fecha = date("Y-m-d H:i:s", $fecha);

        $cons  = "INSERT INTO web (uid,carpeta,fecha,remitente,destinatario,cc,cco,asunto) VALUES (".$uid.",'".$carpeta."','".$fecha."','".$remitente."','".$destinatario."','".$cc."','".$cco."','".$asunto."')";
        $mysqli->query($cons);
    }
}
}
//fin guardar mail

$hostname = '{localhost:143}Inbox';
$username = '##########';
$password = '###';


$tiempoInicio = microtime(true);
/* Intento de conexión */
$conn = imap_open($hostname,$username,$password) or die('No se pudo conectar con: usuario: '.$username.' y clave: '.$password.' ' . imap_last_error());

$numMsg = imap_num_msg($conn);

for($i=$mailInicio;$i<=$numMsg;$i++){

$header = imap_header($conn,$i) ;
$fromInfo = $header->from[0];
$replyInfo = $header->reply_to[0];
$toInfo = $header->to[0];
$ccInfo = $header->cc[0];
$bccInfo = $header->bcc[0]; 

$detalles = array(
    "mailRemitente" => (isset($fromInfo->mailbox) && isset($fromInfo->host))
        ? $fromInfo->mailbox . "@" . $fromInfo->host : "",
    "nombreRemitente" => (isset($fromInfo->personal))

    "mailCco" => (isset($bccInfo->mailbox) && isset($bccInfo->host))
        ? $bccInfo->mailbox . "@" . $bccInfo->host : "",
    "nombreCco" => (isset($bccInfo->personal))
        ? $bccInfo->personal : "",
    "asunto" => (isset($header->subject))
        ? $header->subject : "",
    "fecha" => (isset($header->udate))
        ? $header->udate : ""
);

$uid = imap_uid($conn,$i);
guardarMail($uid,'Inbox',$detalles["fecha"],$detalles["mailRemitente"],$detalles["mailDestinatario"],$detalles["mailCc"],$detalles["mailCco"],$detalles["asunto"],'','','','','');

$tiempoActual = microtime(true);

$deltaTiempo = $tiempoActual - $tiempoInicio;


if($deltaTiempo > 1 ){


    break;

}



}
echo $i.'/'.$numMsg;

the problem is that the script runs for about 5 times, but at somepoint the ajax can't load the php anymore, it gives error 500

Answer 1

Tech support of the hosting changed php version from 5.2 to 5.3 and now it works. It works and seems to run faster.
