PHP ODBC error: tried to allocate 4294967293 bytes -

i've been trying make work whole day , think need help. have read/tried lot of related posts here nothing seems solve problem.

i'm getting error:

fatal error: out of memory (allocated 524288) (tried allocate 4294967293 bytes) in c:\inetpub\wwwroot\sandbox\odbc.php on line 26

when executing following code:

$query = "select * table";  $res = odbc_exec($connection, $query);  while( $row = odbc_fetch_array($res) ) {     print_r($row);  } 

the "line 26" referred error message line.

while( $row = odbc_fetch_array($res) ) 

other info: running php version 5.3.24 on iis 7, windows server 2008; php memory_limit: 500m (have come increase insanely high after lower numbers didn't work)

i ran exact same error , turned out table selecting had field of type nvarchar(max). reducing length of field (to nvarchar(100), example) resolved issue me.
