Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2002-10-05 16:55:57] [EMAIL PROTECTED] I used PHP 4.2.3 zip file for windows. The GD extension and the Java extension are used and the appropriate paths are set for in Java in the php.ini PHP is crashing when I try to get the value of a specific point in my 2 dimensional array. The error occurs on the second attempt in the same script to read from the array. Below I will include the java code used and the php code that calls the java object. Java Code: /** * Filter class designed to do computations for a php script * * @author (Peter Kroll) * @version (2002-10-02) */ public class Filter { /** * Constructor for objects of class Filter */ public Filter() { } /** * applyFilter * * @param * filterMatrix: 2 dimensional array of integers * imageMatrix: 2 dimensional array of integers * @return * newImageMatrix: 2 dimensional array of integers */ public int[][] applyFilter(double [][] filterMatrix, int filterDimension, int [][] imageMatrix, int imageSizeX, int imageSizeY) { int countX; int countY; double sum = 0; int posX; int posY; int pixelValue; int temp; int [][] newImageMatrix = new int[imageSizeX][imageSizeY]; // Apply filter to image for(countX = 0; countX < imageSizeX; countX++) { for(countY = 0; countY < imageSizeY; countY++) { sum = 0; for(posY = 0; posY < filterDimension; posY++) { for(posX = 0; posX < filterDimension; posX++) { if(countX - posX < 0 || countY - posY < 0) { pixelValue = 0; } else { pixelValue = imageMatrix[countX-posX][countY-posY]; sum = sum + imageMatrix[countX-posX][countY-posY] * filterMatrix[filterDimension - 1 - posX][filterDimension - 1 - posY]; } } } newImageMatrix[countX][countY] = (int) sum; } } return newImageMatrix; } } PHP code: // Apply filter to image $FilterObject = new Java("Filter"); $newImageMatrix = $FilterObject->applyFilter($filter, $filterDimension, $imageMatrix, $imageSizeX, $imageSizeY); $tempVal = $newImageMatrix[0][0]; print $tempVal . "<BR>\n"; $tempVal = $newImageMatrix[1][1]; print $tempVal . "<BR>\n"; The PHP code above is not my whole script but the part that calls Java and causes the error. Please note that the Java compiles fine and there are no errors in the PHP. The variables passed into the Java method are the same type as required by the Java method. I am able to read one value from the returned matrix and print it to the screen on the second attempt php crashes, this bug is reproducable 100% of the time. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19775&edit=1
