I'm glad that Bastion left the above post about the mysterious int flag. He just helped to fix a problem that I've spent six hours on. Here's my code:
for($ct=1; $ct<=$numrecs; $ct++) {
$rec = "";
$nr=socket_recv($fp,$rec,77,0);
print "Rec # $ct -->";
print "$rec";
print "<br>";
}
The code is pretty simple, it just loops through all my records and prints them out. All records are 77 bytes and all end with a period. The first 36 records print perfectly then at 37 things go bad. The records start to get offset. The last few characters of the 37th record end up printing on the 38th record. The data on the sending side was perfect, so I knew that the problem was with socked_recv.
After reading the above post I tried changing the int flag. Changing the flag to 2 worked:
$nr=socket_recv($fp,$rec,77,2);
Now everything lines up perfectly. I had always left int flag as 0 since it's undocumented.
