[Php-java-bridge-users] multidimensional arrays

[Michael P. D. <dob...@we...>]

Hi Jost,

sorry an email done again of me, but either I make something wrong or
perhaps I have found a little bug. However I hope you can help me ;-)

If java returns a multidimensional array, the bridge takes this as a nested
one-dimensional array. 

A small example:

public class javatest {

  public javatest() {
  }

  public static Object[][] test3(String testvar1, String testvar2, String
testvar3, String testvar4) {
    Object[][] testobj = null;
    testobj = new Object[2][2];
    testobj[0][0] = testvar1;
    testobj[0][1] = testvar2;
    testobj[1][0] = testvar3;
    testobj[1][1] = testvar4;
    return testobj;
  }
}


<?php
    $testvar = new Java('javatest');
    $testobj3 = $testvar->test3("Field 1,1","Field 1,2","Field 2,1","Field
2,2");
    print "testobj3: ";
    print_r($testobj3);
    print "<br>";
    for ($i = 0; $i < 2; $i++) {
      for ($j = 0; $j < 2; $j++) {
        print "$i,$j: " . $testobj3[$i][$j] .'  <br>';
      }
    }
    print "0,2: " . $testobj3[0][2] .'  <br>';
    $phptestobj = array(array("Field 1,1","Field 1,2"),
                        array("Field 2,1","Field 2,2"));
    print "phptestobj: ";
    print_r($phptestobj);
    print "<br>";
    for ($i = 0; $i < 2; $i++) {
      for ($j = 0; $j < 2; $j++) {
        print "$i,$j: " . $phptestobj[$i][$j] .'  <br>';
      }
    }
?>

Output:
testobj3: Array ( [0] => Array ( [0] => Field 1,1 [1] => Field 1,2 [2] =>
Array ( [0] => Field 2,1 [1] => Field 2,2 ) ) ) 
0,0: Field 1,1 
0,1: Field 1,2 
1,0: 
1,1: 
0,2: Array 
phptestobj: Array ( [0] => Array ( [0] => Field 1,1 [1] => Field 1,2 ) [1]
=> Array ( [0] => Field 2,1 [1] => Field 2,2 ) ) 
0,0: Field 1,1 
0,1: Field 1,2 
1,0: Field 2,1 
1,1: Field 2,2

Thanks and many Greetings
