well, the PHP/Java Bridge is only the XML protocol, as
such it should run with any PHP version >= 4.3.2. I.e
with any PHP version which has a working version of
fsockopen.

We publish PECL and PEAR extensions for convenience,
but these extensions aren't necessary to call out to
Java libraries. 

The following example demonstrates how easy it is to
call out to Java libraries with nothing but fsockopen,
fread and fwrite:

<?
class Protocol {
  var $c;
  function __construct() { 
    $this->c=fsockopen("127.0.0.1",9267); 
    fwrite($this->c, chr(0100)); // mode 0 0, see
PROTOCOL.TXT
  }

  function createBegin($s) { 
    fwrite($this->c,sprintf("<C v=\"%s\" p=\"I\">",
$s)); 
  }

  function createEnd() { fwrite($this->c, "</C>"); }

  function invokeBegin($o, $m) { 
    fwrite($this->c, sprintf("<I v=\"%d\" m=\"%s\"
p=\"I\">", $o, $m)); 
  }

  function invokeEnd() { fwrite($this->c, "</I>"); }

  function writeString($s) {
      fwrite($this->c, sprintf("<S v=\"%s\"/>", $s));
  }

  function writeInt($s) {
    $p="O"; if($s<0) { $p="A"; $s*=-1; }
    fwrite($this->c, sprintf("<L v=\"%d\" p=\"%s\"/>",
$s, $p));
  }

  function writeObject($s) {
    fwrite($this->c, sprintf("<O v=\"%d\"/>",
$s->java));
  }

  function writeVal($s) {
    if(is_string($s)) {
      $this->writeString($s);
    } else if(is_int($s)) {
      $this->writeInt($s);
    } else {
      $this->writeObject($s);
    }
  }

  function getResult() {
    $res = fread($this->c, 8192); 
    $ar = sscanf($res, "%s v=\"%s");
    return substr($ar[1], 0, strpos($ar[1], "\""));
  }
}

function getProtocol() {
  static $protocol; if(!isset($protocol))
$protocol=new Protocol();
  return $protocol;
}

class J/*ava*/ {
  var $java;
  function __construct() {
    if(!func_num_args()) return;
    $protocol=getProtocol();
    $ar = func_get_args();
    $protocol->createBegin(array_shift($ar));
    foreach($ar as $arg) { $protocol->writeVal($arg);
}
    $protocol->createEnd();
    $ar = sscanf($protocol->getResult(), "%d");
    $this->java=$ar[0];
  }
  function __call($method, $args) {
    $protocol=getProtocol();
    $protocol->invokeBegin($this->java, $method);
    foreach($args as $arg) {
$protocol->writeVal($arg); }
    $protocol->invokeEnd();
    $proxy = new J();
    $ar = sscanf($protocol->getResult(), "%d");
    $proxy->java=$ar[0];
    return $proxy;
  }
  function toString() {
    $protocol=getProtocol();
    $protocol->invokeBegin("", "castToString");
    $protocol->writeVal($this);
    $protocol->invokeEnd();
    return $protocol->getResult();
  }
}
// Test
$i1 = new J("java.math.BigInteger",  "1", 2);
$i2 = new J("java.math.BigInteger",  "11", 2);
$i3 = $i1->add($i2);
echo $i3->toString() . "\n";
?>

To run the above example start the JavaBridge.jar, for
example by double-clicking on it or with:

java -jar JavaBridge.jar INET:0 4 JavaBridge.log
