我正在尝试将 PHP 数组插入到 mysql 数据库中,但是遇到了这个特定数组的问题。我正在尝试创建一个需要
array( 0 => array ( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => value', 'col5' => 'value', 'col6' => array ( 'string' => array ( 'col7' => 'value' , 'col8' => 'value'), ), ),
1 => array ( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => array ( ), 'col5' => 'value', 'col6' => array ( 'string' => array ( ), ), ),
2 => array ( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => array ( ), 'col5' => 'value', 'col6' => array ( 'string' => array ( ), ), ), )
并分隔每个编号的数组并将其格式化为:
array( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => 'value', 'col5' => 'value', ['col6' => 'value','col7' => 'value',] )
array( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => 'value', 'col5' => 'value', ['col6' => 'value','col7' => 'value',] )
array( 'col1' => 'value', 'col2' => 'value', 'col3' => 'value', 'col4' => 'value', 'col5' => 'value', ['col6' => 'value','col7' => 'value',] )
取决于有多少行。请记住以下条件:
+8 cols is just an example, the range can fluctuate greatly.
+Cols containing a array must be non existent if it empty, like in [1] and [2], but not [0].
+Any column could contain a empty or full array. if it contains a full array, it needs to be flatten while retaining it's value.
+Some arrays might have greater then 2 nested arrays. (elements)
+Not all of the arrays have nested arrays, they are already formatted correctly. These arrays can not be affected by the PHP function i'm trying to create.
我很难过,我创建的每个功能都失败了。提前感谢大家。
更新我用Var_export
这个函数来获取上面的数组。
function flatten($array, $preserve_keys = false)
{
if (!$preserve_keys) {
$array = array_values($array);
}
$flattened_array = array();
foreach ($array as $k => $v) {
$flattened_array[$k] = $v;
if (is_array($v)) {
$flattened_array = array_merge($flattened_array, call_user_func(__FUNCTION__, $v, $preserve_keys));
} elseif ($preserve_keys) {
$flattened_array[$k] = $v;
} else {
$flattened_array[] = $v;
}
}
return (array)$flattened_array;
}
