Description:
------------
Hello!

The fgetcsv() function do not working properly.
Below there is a fragment of the source data file. 

----------------source data file---------------

SZ | 7784252D00000  |  | 29.13
SZ | 7784265DA1000  |  | 21.23
SZ | 7784265DA10PG  | "Title ""V6"" | 17.9
SZ | 784270C20000   |  | 29.9
SZ | 784360E00000   |  | 29.41

---------------------end data file--------------

On big input files the function after line number 3 of data file need more and more memory and then crashes with trying to allocate memory.

Reproduce code:
---------------
#!/usr/bin/php
<?php

$delimiter = "|";

$data_file = fopen('price.txt','r') or die('Cannot open price.txt !');

while( !feof($data_file) ){

    $buffer = fgetcsv( $data_file, 1500, $delimiter );

    $buffer[0] = trim( $buffer[0] );
    $buffer[1] = trim( $buffer[1] );
    $buffer[2] = trim( $buffer[2] );
    $buffer[3] = trim( $buffer[3] );

    $tmp_file = fopen('./csv/'.$buffer[0].'.csv', 'a+');
    fwrite($tmp_file, $buffer[1] . $delimiter . $buffer[2] . $delimiter . $buffer[3]."\n" );
    fclose( $tmp_file );
}

----------------
