Hello, I created a class that I use to open socket connections. I can connect to a target just fine and I can retrieve data. The real problem is that I don't seem to be able to acquire all the data when the response is longer than 600 or so characters long. 600 is a rough estimate because due to the fact that when I reload the page, sometimes I can acquire more data, sometimes I acquire less ~3 characters. I figured the variant meant that there was an issue with the script timing out before all the data was acquired, but even if I set stream_set_timeout () to 10 minutes, it doesn't change the result. Here is the class: <?php /** * SocketConnection manages a connection that is based upon the PHP * fopensock function. This code is based off of code originally * writen by Antone Roundy. * * @author * @version 1.1 */ class SocketConnection extends Connection { private $connectionAddress; private $port; /** * Constructs a new socket connection. */ public function SocketConnection ( $connectionAddress, $port ) { parent::__construct (); $this->connectionAddress = $connectionAddress; $this->port = $port; } /** * This methods attempts to make a connection to the socket. */ public function connect () { $connectionErrors = parent::getConnectionErrors (); // If the wrong version of PHP is running... if ( ! PHPUtility::isValidPHPVersion ( '5.0.0' ) ) { // Add version error. $connectionErrors->addError ( new PHPVersionError () ); } // If no connection address has been provided... if ( ! strlen ( $this->connectionAddress ) ) { // Add null connection address error. $connectionErrors->addError ( new NullConnectionAddressError () ); } // If there are no errors... if ( $connectionErrors->getTotalErrors () == 0 ) { // Attempt to establish a connection. $connectionHandler = @fsockopen ( $this->connectionAddress, $this->port, $errorNumber, $errorString ); // If a connection has been established... if ( $connectionHandler ) { // Store the connection. parent::setConnection ( $connectionHandler ); stream_set_timeout ( parent::getConnection (), 0 ); } // If a connection has not been established... else { // Add the error generated by the system. parent::getConnectionErrors ()->addError ( new ConnectionError ( $errorString ) ); } } } /** * This methods attempts to severe the connection. */ public function disconnect () { $connection = parent::getConnection (); // If a connection exist... if ( $connection ) { // Kill the connection. fclose ( $connection ); parent::setConnection ( null ); } } /** * This method reads the socket stream buffer for any unread * data and grabs it. */ public function getResponse () { $connection = parent::getConnection (); // Make sure that a connection exist if ( $connection ) { parent::clearBuffer (); $response = ''; // Cycle through the connection data atleast once. do { $response .= fread ( $connection, 8192 ); $socketStatus = socket_get_status ( $connection ); } while ( $socketStatus [ 'unread_bytes' ] ); $response = trim ( preg_replace( "/^.*?\n(.*)\n[^\n]*$/", "$1", $response ) ); parent::setBuffer ( $response ); } } /** * This method sends a command to the connection and records the response * in the buffer. */ public function sendCommand ( $command ) { $connection = parent::getConnection (); if ( $connection ) { fputs ( $connection, $command . "\r" ); sleep ( 1 ); $this->getResponse (); } } } ?> The method responsible for acquiring data is SocketConnection::getResponse (). The following is what I get when I create a SocketConnection and connect to a system. getcc <CalibrationCoefficients DeviceType = 'SBE37SI-RS232' SerialNumber = '03706087'> <Calibration format = 'TEMP1' id = 'Temperature'> <SerialNum>03706087</SerialNum> <CalDate>04-Aug-08</CalDate> <A0>7.668374e-05</A0> <A1>2.643877e-04</A1> <A2>-1.718200e-06</A2> <A3>1.318193e-07</A3> </Calibration> <Calibration format = 'WBCOND0' id = 'Conductivity'> <SerialNum>03706087</SerialNum> <CalDate>04-Aug-08 </CalDate> <G>-9.758729e-01</G> <H>1.390257e-01</H> <I>-2.276137e-04</I> <J>3.585628e-05</J> <P The following is what I suppose to have: <CalibrationCoefficients DeviceType = 'SBE37SI-RS232' SerialNumber = '03706087'> <Calibration format = 'TEMP1' id = 'Temperature'> <SerialNum>03706087</SerialNum> <CalDate>04-Aug-08</CalDate> <A0>7.668374e-05</A0> <A1>2.643877e-04</A1> <A2>-1.718200e-06</A2> <A3>1.318193e-07</A3> </Calibration> <Calibration format = 'WBCOND0' id = 'Conductivity'> <SerialNum>03706087</SerialNum> <CalDate>04-Aug-08 </CalDate> <G>-9.758729e-01</G> <H>1.390257e-01</H> <I>-2.276137e-04</I> <J>3.585628e-05</J> <PCOR>-9.570000e-08</PCOR> <TCOR>3.250000e-06</TCOR> <WBOTC>2.512962e-07</WBOTC> <REFERENCE_PRESSURE>0.000000e+00</REFERENCE_PRESSURE> </Calibration> </CalibrationCoefficients> Does anyone have any ideas as to why my content is being cut off?
