PHP Bug Type: Documentation problem
Bug description: Not understandible ereg()-warning "Invalid preceding regular
expression"
Description:
------------
The warning only occurs on very few plattforms. I probably could fix it in
my code, if I could only understand it's meaning. If you google for the
error-message you will find tons of broken pages with the same error but
no explanation.
Reproduce code:
---------------
/* NOT reproducable */
class ListBlockColHtml extends ListBlockCol
{
function render_tr(&$obj, $style="") {
if(!isset($obj) || !is_object($obj)) {
trigger_error("ListBlockColHtml->render_tr() called
without valid
object",E_USER_WARNING);
return;
}
$key= $this->key;
$format= $this->format;
$rest=$this->format;
$style= $this->style
? "class='$this->style'"
: '';
while( ereg("{\?([a-z_]*)}(.*)",$rest, $matches) ) { ###
causes error
$key=$matches[1];
$rest=$matches[2];
$value= isset($obj->$key) ? $obj->$key : "??$key";
$format=ereg_replace("{\?$key}",$value,$format);
}
print "<td $style>$format</td>";
}
}
