Allowed memory size of 33554432 bytes exhausted

Hello everybody,

I'm using nusoap library and this is the first time i'm working on SOAP services. I managed to create a webservice using PHP - NuSOAP library. The web service internally calls the database retrieves results and sends back.
Today i got this error while executing the code. The web service gives results when i limit my query to 3000. But i need to get all 10000 + results.

Allowed memory size of 33554432 bytes exhausted (tried to allocate 129 bytes) in server/path/lib/nusoap.php on line 809.

I checked on net and saw the solution to set the memory size to 16 mb. I tried ini_set("memory_limit","16M");
But i dont know where this function should be pasted. I tried and got error.
One more thing i used mysql_free_results function to free the memory in my code.

Please tell me setting the memory size to 16M will solve my problem or not?
Also is there any other thing i need to do?


Thanks,
Rohan7

your script exhausted 32MB, by setting new limit of 16MB you can't solve the problem. You need more than 32MB, or rethink what you're doing and prehaps run smaller requests.

hi dmitri,

Thanks for the suggestion. Actually i'm quering a database and getting the results. For that i used mysql_fetch_assoc function to get associative array. I have defined the array as below.

$server->wsdl->addComplexType(
'Row',
'complexType',
'struct',
'all',
'',
array(
'id' => array('name' =>'id','type'=>'xsd:int'),
'title' => array('name' =>'title','type'=>'xsd:string'),
'information' => array('name' =>'information','type'=>'xsd:string')
)
);

$server->wsdl->addComplexType(
'Entry',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Entry[]'))
);

$server->register(
'UdefFn',
array('inputString'=>'xsd:string'),
array('return'=>'tns:Entry'),
$NAMESPACE);

function UdefFn($inputString){
{
// Connection to database and query to database
$BigArr = array();
while($row = mysql_fetch_assoc($result))
{
array_push($BigArr, $row);
}
return $BigArr;
}

My database sometimes returns more than 10000 rows. I get 3000 entries easily. But more than that i get error.

Do i need to define the complexType differently ?
How can i achieve gettin all records?
Thanks

I would break it into smaller chunks. It'll reduce the load on the server (both PHP & DB if the DB supports getting records in chunks) as well as making getting the results easier.

Fix NuSOAP memory size exhausted - change debug level to 0

SOLUTION for memory leak with NuSOAP.

For production purposes (or if you are processing a lot of data) you just need to change your $GLOBALS['_transient']['static']['nusoap_base']->globalDebugLevel variable from 9 to 0.

Depending on your version of NuSOAP, this variable definition may be located in the nusoap.php file at the top.

$GLOBALS['_transient']['static']['nusoap_base']->globalDebugLevel = 0;

NuSoap appears to keep track of debug information by simple appending to this variable.

Good luck!
