Physco, your suggestion of the following worked a treat preg_match("#$GPRMC.*#", $input, $match); $GPRMC_line = $match[0]; gave me an ouput of the following... root@voyage:/usr/utils/sattrack# ./check_gps.php GPRMC,001025.000,V,5310.5798,N,00226.2040,W,0.0,0.0,170312,,,N*60 root@voyage:/usr/utils/sattrack# great thing now is there are a dozen other string i can latch onto using the same regex but to answer your questions the $ at the start of GPRMC string does infact mean nothing and the data returned from $read is part of the serial command issued to get the data in the first place all i need to do now is strip that result now into an array using the , as a delimiter for sectioning thanks guys )))

Hi Guys, Think this a simple one but been stuck for a few hours and tearing my hair out... ive got a serial command querying a GPS dongle which returns an output once queried $read = $serial->readPort(); Once the query has been returned it give me and output like the following $GPRMC,120329.000,A,5310.5615,N,00226.2420,W,0.0,10.0,160312,,,A*43 $GPGGA,120329.000,5310.5615,N,00226.2420,W,1,04,25.5,-0.3,M,59.1,M,,0000*52 $GPVTG,10.0,T,,M,0.0,N,0.0,K,A*3C $PMST200,00,204*1E $PMST200,00,204*1E $PMST200,00,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $GPGLL,5310.5615,N,00226.2420,W,120329.00,A,A*72 $GPGSA,A,3,04,07,10,13,,,,,,,,,36.1,25.5,25.5*06 $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,00,204*1E $PMST200,00,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $GPRMC,120330.000,A,5310.5615,N,00226.2420,W,0.0,10.0,160312,,,A*4B $GPGGA,120330.000,5310.5615,N,00226.2420,W,1,04,25.5,-0.3,M,59.1,M,,0000*5A $GPVTG,10.0,T,,M,0.0,N,0.0,K,A*3C $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E Im basically trying to preg_match the GPRMC line but recover the full line, i will then explode it later and break it down by the commas i the string... $GPRMC,120329.000,A,5310.5615,N,00226.2420,W,0.0,10.0,160312,,,A*43 i need the above line each time i query the dongle rather than all the other stuff it generates any one got a clean way of doing it? ive tried this but all it give me is the following.. if (preg_match("/GPMRC/", $read, $result)) { print "$result[0]"; } which give mes this only root@voyage:/usr/utils/sattrack# ./check_gps.php GPRMC root@voyage:/usr/utils/sattrack#

Sal... You the man my friend, im not that great with regular expressions but i knew thats what i need to do to get my output. Many thanks for taking a look at that for me i knew some one on here would be able to help me... thanks so much Alan

Hi There, Im a little bi lost and not sure where to start with this one, ive got a small gps receiver which im polling over a serial connection, each time i poll the device i get a load of rubbish back like this... $GPRMC,223450.000,A,5310.5785,N,00226.2042,W,0.0,25.8,291109,,,A*49 $GPGGA,223450.000,5310.5785,N,00226.2042,W,1,06,2.1,22.3,M,59.1,M,,0000*7D $GPVTG,25.8,T,,M,0.0,N,0.0,K,A*32 $PMST200,00,204*1E $PMST200,00,204*1E $PMST200,00,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E $GPGLL,5310.5785,N,00226.2042,W,223450.00,A,A*73 $GPGSA,A,3,02,04,05,07,08,10,,,,,,,4.5,2.1,4.0*39 $PMST200,??,204*1E $PMST200,??,204*1E $PMST200,??,204*1E As they are never ever in the same order i cant really use reg_exp to get what i want, basically im trying to capture the following and then use split to break them down further and insert into a DB $GPRMC,223450.000,A,5310.5785,N,00226.2042,W,0.0,25.8,291109,,,A*49 how can i just get it to extract that line and nothing else unless i ask it to???? the output from the serial devic come is extract using this $read = $serial->readPort(); than i just echo read etc etc and get my text which is further up, any ones help or suggestions would be brill... thanks in advance Alan

Hi All, Ive got a small piece of java script code which basically gives me a status when the image is checked and another status when the image is un checked. I need 8 images in total with 8 different status, ive got the code working ok but something i cant do as im not that offay with javascript is make sure that if one image is selected, when another image is selected the origianl image which was selected is returned to its previosu state.. <script type="text/javascript"> function toggleButtonV1() { var value = document.getElementById('Viewing1').value; if(value == 'on') { document.getElementById('Viewing1').value = 'off'; document.getElementById('toggleButtonImgV1').src = 'archive/images/pressed/viewing/pressed-1.jpg'; document.getElementById('buttonValueViewing').innerHTML = '1'; } else { document.getElementById('Viewing1').value = 'on'; document.getElementById('toggleButtonImgV1').src = 'archive/images/viewing/index_09.png'; document.getElementById('buttonValueViewing').innerHTML = '0'; } } function toggleButtonV2() { var value = document.getElementById('Viewing2').value; if(value == 'on') { document.getElementById('Viewing2').value = 'off'; document.getElementById('toggleButtonImgV2').src = 'archive/images/pressed/viewing/pressed-1.jpg'; document.getElementById('buttonValueViewing').innerHTML = '2'; } else { document.getElementById('Viewing2').value = 'on'; document.getElementById('toggleButtonImgV2').src = 'archive/images/viewing/index_11.png'; document.getElementById('buttonValueViewing').innerHTML = '0'; } } </script> <!-- Debug Start --> <font face="Tahoma" style="font-size: 8pt">Value: </font> <span id="buttonValueViewing"> </span> <!-- Debug Finish --> <!-- Mysql Query Start --> if($row->status == "invisible" ) { echo <<<END END; }else if ($row->status == "active" ) { echo <<<END <img src="$row->image_location" onclick="toggleButtonV2();" id="toggleButtonImgV2"> <input type="hidden" name="Viewing2" id="Viewing2" value="on"> END; }else{ echo <<<END <img src='$row->image_disabled'> END; } } <!-- Mysql Query Finish --> thats the bsisc code ( no hero on that side but it works to a degree, im hoping once ive figured it all out i can tidy it all up. Does any one know how i can make sure that only one image at a time selected as i cant and dont need multiple images selected at any one time. any help would be appreciated Kind Regards Alan

Hi All, Just a quick one not really sure where to start with it... Im trying to create a matrix screen which will be used to switch audio and video outputs on a matrix switcher. its using rs232 commands which i already have working... what id like to be able to do is create a screen layout which has 8 audio inputs, 8 video inputs and 8 screen outputs but i need the image of the zone to do the following... i need to string together code on the fly when the image button is pressed so if some one presses images 1 ( screen output 1 ) and then selects audio input 1 and video input 1 i then get an end result of a string which can then be presented to the rs232 interface which will then change the status. once i can get the string formulas sorted i can then add them to a database each time its called so atleast if you exit the matrix screen it will have the last outputs and inputs as select images. i know this may sound really complicated but im hoping some one can help in some way in a nutn shell i need to be able to use images to build a string then input it to a script all on the same page. Also as a last thing the script needs to know that on the last input it then needs to trigger the process, basically output 1, video input 1, audio input 1 ( trigger ) im hoping some one can help and get me started Alan
