php parse array values
提问by bikey77
I'm not very good when it comes to arrays so here's probably something very simple but not for me! I'm getting an array of values via POST and I need to parse them and store the values in a table. How should I use the classic parsing such as:
我在数组方面不是很好，所以这可能是一些非常简单但不适合我的东西！我通过 POST 获取一组值，我需要解析它们并将值存储在表中。我应该如何使用经典解析，例如：
foreach($array as $a) {
$text = $a->text;
$name = $a->user->name;
}
etc to parse an array looking like this:
等来解析一个看起来像这样的数组：
[item] => Array
(
[tags] => Array
(
[0] => Bluetooth
[1] => WiFi
[2] => USB
)
)
This is the entire POST array:
Array
(
[prodid] =>
[Submit] => Save
[productcode] => 797987
[cat_id] => 66
[brand] => Fysiomed
[name] => asdc asdc asd c
[productnew] => yes
[item] => Array
(
[tags] => Array
(
[0] => Bluetooth
[1] => WiFi
[2] => USB
)
)
[size] => 1
[barcode] => 7979871
[price] => 233.00
[priceoffer] => 0.00
[stock] => 50
[weight] => 0.30
[orderby] => 1
)

if(isset($_POST) && !empty($_POST)) {
foreach($_POST as $key => $value) {
if($key == 'item') {
echo $value[$key]['tag'][0]. '<br>';
echo $value[$key]['tag'][1]. '<br>';
echo $value[$key]['tag'][2]. '<br>';
}
}
}

if( isset($_POST['item']) && isset($_POST['item']['tags']) ){
foreach($_POST['item']['tags'] as $tag){
//do stuff...e.g.
echo $tag;
}
}

Looks like your array is shaped like this, check this
看起来你的阵列形状像这样，检查这个
$array = array( "item" => array( "tags" => array("Bluetooth", "Wifi", "USB" ) ) );
var_dump($array);
You will see something like this
你会看到这样的东西
array(1) {
["item"]=>
array(1) {
["tags"]=>
array(3) {
[0]=>
string(9) "Bluetooth"
[1]=>
string(4) "Wifi"
[2]=>
string(3) "USB"
}
}
}
Now for parsing this array,
现在解析这个数组，
foreach($array as $in => $val) {
// as $array has key=>value pairs, only one key value pair
// here $in will have the key and $val will have the value
// $in will be "item"
print $in; // this will print "item"
foreach($val as $in2 => $val2 ){
// only one key : "tags"
print $in; // this will print "tags"
print $val2[0]; // this will print "Bluetooth"
print $val2[1]; // this will print "Wifi"
}
}
I hope this clears you doubt regarding arrays.
我希望这可以消除您对数组的疑虑。

Are you just trying to get the text out? try this.
你只是想把文字弄出来吗？尝试这个。
foreach($array['item']['tags'] as $tag) {
$text = $tag;
}
