PHP 从数组中检索信息
PHP retrieve information from array
我需要从数组中获取值。
我的代码:
$tags = $array['bePVM'][''];
echo ('<form action="" method="POST">');
for($o = 0; $o<$i; $o++){
echo "<br>Užsakymo: <b> ",$data2DArray[$o][0], "</b> Price witout VAT: ",'<input type="text" name="bePVM[]" value="">'," VAT: ",'<input type="text" name="PVM[]" value="">'," Price with VAT: ",'<input type="text" name="suPVM[]" value="">',"<br>";
}
echo ('<input type="submit" value="">');
echo ('</form>');
print_r($_POST);
echo $tags[1];
我有这个输出:
Warning: Trying to access array offset on value of type null
Array ( [bePVM] => Array ( [0] => 100
[1] => 200 )
[PVM] => Array ( [0] => 21
[1] => 42 )
[suPVM] => Array ( [0] => 121
[1] => 242 )
)
如何回显 [bePVM][1] 200 在哪里?
谢谢
How can i echo [bePVM][1] where is 200?
如果输出来自 print_r($_POST);
那么这应该将 200
写入输出:
echo $_POST['bePVM'][1];
