Dear List!
It seems that I found a bug concerning PHP Mapscript or MapScript in general.
The result is a "Premature end of script headers: php-cgi.exe" and a "Internal
Server error 500"
In our web application I dynamically change the "DATA" attribute of one layer
to retrieve the correct objects out of the Oracle 10g database. This works
great as long the data String is not longer than 2036 characters.
In php I set the DATA string with "$layerObj->set("data" , $dataString);". A
var_dump($dataString) shows that it is 2037 characters long. But debugging at
the database side showed that only 1524 characters are included in the select
statement. So a total of 513 (Not 512?) characters are cut off. A $dataString
containing 2036 characters work fine.
Because the DATA string is only a part of the total SQL string that is
submitted to the database (when navigating a map, a " WHERE SDO_FILTER" clause
is added) the total SQL string for retrieving the objects (that are burnt into
the WMS GETMAP image) gets about 2215 characters long which works fine with
sqlplus.
It seems that the "$layerObj->set("data" , $dataString);" line doesn't work for
strings longer than 2036 characters.
Can someone confirm this?
Thanks for any reply,
Michael
