Php -检查矩形是否重叠

function isRectangleOverlap($rec1, $rec2) {
    // 获取矩形1的坐标
    $rec1_x1 = $rec1[0];
    $rec1_y1 = $rec1[1];
    $rec1_x2 = $rec1[2];
    $rec1_y2 = $rec1[3];
    
    // 获取矩形2的坐标
    $rec2_x1 = $rec2[0];
    $rec2_y1 = $rec2[1];
    $rec2_x2 = $rec2[2];
    $rec2_y2 = $rec2[3];
    
    // 判断两个矩形是否重叠
    if ($rec1_x1 >= $rec2_x2 || $rec1_x2 <= $rec2_x1 || $rec1_y1 >= $rec2_y2 || $rec1_y2 <= $rec2_y1) {
        return false;
    } else {
        return true;
    }
}

// 示例用法
$rec1 = [0, 0, 2, 2];
$rec2 = [1, 1, 3, 3];
$result = isRectangleOverlap($rec1, $rec2);
if ($result) {
    echo "两个矩形重叠";
} else {
    echo "两个矩形不重叠";
}
