PHP socket implementation and Java side readFully docking

java:

<code>DataInputStream stream = <span>new</span> DataInputStream(<span>new</span> BufferedInputStream(socket.getInputStream()));
<span>int</span> i=  stream.readInt();
<span>byte</span>[] b = <span>new</span><span>byte</span>[i];
stream.readFully(b);
System.<span>out</span>.println(<span>new</span> String(b));</code>

php:

<code><span><span>function</span><span>writeInt</span><span>(<span>$socket</span>, <span>$i</span>)</span>
{</span><span>$data</span> = pack(<span>'N'</span>, <span>$i</span>); 
    socket_write(<span>$socket</span>, <span>$data</span>);
}
writeInt(<span>$sock</span>,strlen(<span>"ZXCV"</span>));
socket_write(<span>$sock</span>,<span>"ZXCV"</span>,strlen(<span>"ZXCV"</span>));
</code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces the connection between PHP socket implementation and Java-side readFully, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
