Hi,
I had an excel file that I couldn't read.
The variable $this->wrkbook was not defined.
I correct it by changing in oleread.inc, in the method __readPropertySets by replacing
if ($name == "Workbook" || $name == "Book") {
$this->wrkbook = count($this->props) - 1;
}
by
if (strcasecmp($name, "Workbook") == 0 || strcasecmp($name, "Book") == 0) {
$this->wrkbook = count($this->props) - 1;
}
