"cristian DOT zuddas AT gmail DOT com" has posted the corrected function
"CSV2Array", but all the same there's an error. For example, function incorrectly
processes a simple csv-file from "MS Excel" (http://wsCat.ka.pp.ru/test.csv) in which
fields any way contain quotes and CR/LF . I has written working function which has successfully
applied to import of the greater production catalog.
<?php
// --------- Test ---------------------------------------
$str=file_get_contents('http://wsCat.ka.pp.ru/test.csv');
$rows=CSV2Array($str);
echo '<table border="1" cellSpacing="2"
cellPadding="2">';
for($i=0;$i<count($rows);$i++)
{
echo '<tr>';
for ($j=0;$j<count($rows[$i]);$j++)
{
echo '<td>'.$rows[$i][$j]. '</td>';
}
echo '</tr>';
}
echo '</table>';
// -----------------------------------------------------
