note 125555 added to function.shmop-write

I guess pack-unpack are the handy functions for encoding/decoding data as/from a binary string for shmop_write/shmop_read. Example: $format='LLLLSSCCCC'; //data format for pack $key=1; if( !($shmid=shmop_open($key,'n',0660,30)) ) die('shmop_open failed.'); //my data to encode: $hd=array('ALIVE1'=>1,'ALIVE2'=>2,'ALIVE3'=>3,'ALIVE4'=>4, 'CRTPTR'=>5,'CRTSEQ'=>6, 'CTW'=>7,'LOCK'=>8,'PLAY'=>9,'MISS'=>10 ); $tmp=pack( $format, $hd['ALIVE1'],$hd['ALIVE2'],$hd['ALIVE3'],$hd['ALIVE4'], $hd['CRTPTR'],$hd['CRTSEQ'],$hd['CTW'],$hd['LOCK'],$hd['PLAY'],$hd['MISS'] ); if( ($w=shmop_write($shmid,$tmp,0))!=24 ) die('write error $w='.$w); And reading from some other process: $key=1; if( !($shmid=shmop_open($key,'w',0,0)) ) die('shmop_open failed.'); $formatR='L4ALIVE/SCRTPTR/SCRTSEQ/CCTW/CLOCK/CPLAY/CMISS'; //data format for unpack $hd=unpack( $formatR, shmop_read( $shmid,0,24) ); echo'hd:<pre>';print_r($hd);echo'</pre>'; ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.156.130 (proxied: 169.252.4.23) ---- Manual Page -- http://php.net/manual/en/function.shmop-write.php Edit -- https://master.php.net/note/edit/125555 Del: integrated -- https://master.php.net/note/delete/125555/integrated Del: useless -- https://master.php.net/note/delete/125555/useless Del: bad code -- https://master.php.net/note/delete/125555/bad+code Del: spam -- https://master.php.net/note/delete/125555/spam Del: non-english -- https://master.php.net/note/delete/125555/non-english Del: in docs -- https://master.php.net/note/delete/125555/in+docs Del: other reasons-- https://master.php.net/note/delete/125555 Reject -- https://master.php.net/note/reject/125555 Search -- https://master.php.net/manage/user-notes.php
