Question

我有转换PHP $_POST virables的问题。

我将此类信息发送到网站：

$_POST['name.1']='xxx';
$_POST['height.1']='100';
$_POST['qty.1']='2';
$_POST['op.1.0']='color';
$_POST['op.1.1']='size';
$_POST['opv.1.0.0']='red';
$_POST['opv.1.0.1']='blue';
$_POST['opv.1.1.0']='xl';
$_POST['opv.1.1.1']='l';
$_POST['opv.1.1.2']='xxl';
$_POST['name.2']='yyy';
$_POST['height.2']='10';
$_POST['qty.2']='4';
$_POST['number.2']='4';
$_POST['op.2.0']='color';
$_POST['op.2.1']='weight';
$_POST['opv.2.0.0']='red';
$_POST['opv.2.0.1']='silver';
$_POST['opv.2.1.0']='90';
$_POST['opv.2.1.1']='60';
$_POST['opv.2.1.2']='42';

我需要将此数据转换为以下格式：

$product[1]['name']='xxx';
$product[1]['height']='100';
$product[1]['qty']='2';
$product[1]['op'][0]='color';
$product[1]['op'][1]=size;
$product[1]['opv'][0][0]='red';
$product[1]['opv'][0][1]='blue';
$product[1]['opv'][1][0]='xl';
$product[1]['opv'][1][1]='l';
$product[1]['opv'][1][2]='xxl';
$product[2]['name']='yyy';
$product[2]['height']='10';
$product[2]['qty']='2';
$product[2]['number']='2';
$product[2]['op'][0]='color';
$product[2]['op'][1]='weight';
$product[2]['opv'][0][0]='red';
$product[2]['opv'][0][1]='silver';
$product[2]['opv'][1][0]='90';
$product[2]['opv'][1][1]='60';
$product[2]['opv'][1][2]='42';


first .1 is product nr.
second .1 is option nr.
third .1 is option value.

Answer 1

$product = array();
foreach ($_POST as $key => $value) {
    $key_array = explode('.', $key);
    $name = array_shift($key_array);
    $subscript = array_shift($key_array);
    $target =& $product[$subscript][$name];
    // If there are remaining elements, they're subscripts into nested array levels
    foreach ($key_array as $next_subscript) {
        $target =& $target[$next_subscript];
    }
    $target = $value;
}

如果您无法修复表单，最懒的方法是通过以下方式转换数组：

Application http_build_query import Tkinter as tk class Testing(tk.LabelFrame): def __init__(self, parent, main): self.buttonWidth = 10 self.parent=parent self.main = main # save the instantiating class tk.LabelFrame.__init__(self, self.parent, text="Test Operations", padx=10, pady=10 ) self.taskButton = tk.Button( self, text="Do A Task", width=self.buttonWidth, command=self.doATask, ) self.taskButton.pack() def doATask(self): #want to execute function in Results.getResult() but don't know how self.main.results.getResult() #<--what you can do class Results(tk.LabelFrame): def __init__(self, parent, main): self.parent = parent self.main = main # save the instantiating class tk.LabelFrame.__init__(self, self.parent, text="Visual Results") self.resultLbl = tk.Label(self, text="Result") self.resultLbl.pack() def getResult(self): self.resultLbl.config(bg='yellow') class Application(tk.Frame): def __init__(self, parent): self.parent = parent tk.Frame.__init__(self, self.parent) self.testing = Testing(self.parent, self) self.results = Results(self.parent, self) self.testing.pack(fill=tk.X) self.results.pack(fill=tk.X) if __name__ == "__main__": root = tk.Tk() root.title("Modular GUI App") Application(root).pack() root.mainloop()
还有几个preg_replace来电：
1. $post =
2. ($_POST)
3. ("/\b(\w+)\.(\d+)\.(\d+)\.(\d+)=/", "prod[$2][$1][$3][$4]=", $post)
然后根据parse_str()将其转换回数组。

（这实际上只能正常工作，因为等值符号会被转义为("/\b(\w+)\.(\d+)\.(\d+)=/", "prod[$2][$1][$3]=", $post)的值。）

你可以做一个手动循环当然“只是”重组键，但这是一个更多的代码。
