multidimensional-array

问题 Inspired this quiestion . Why does - void display(int p[][SIZE]) // allowed and void display(int p[][]) // not allowed ? 回答1: Because arrays decay to pointers when passed to a function. If you do not provide the cardinality of the second dimension of the array, the compiler would not know how to dereference this pointer. Here is a longer explanation: when you write this p[index] the compiler performs some pointer arithmetic to find the address of the element that it needs to reference: it

问题 I have the following HTML form, which is being generated dynamically from a table in a MySQL database. <form method="post" name="chapters" action="ChaptersUpdate.php"> <input type='text' name='id' value='{$row['id']}'> <input type='text' name='name' value='{$row['name']}'> <input type='password' name='password' value={$row['password']};> <input type='submit'> </form> I am looking for a way to make it such that when the form is submitted, the following data structure gets passed in $_POST:

问题 I have function that returns the following multidimensional array. I don't have control of how the array is formed. Im trying to access the 'Result' elements. This issue is, the name of the parent elements constantly changing. The location of the 'Result' element is always the same (as the is the name "Result"). Is it possible to access that element without know the name of the parent elements? Array ( [sHeader] => Array ( [aAction] => ActionHere ) [sBody] => Array ( [CreatePropertyResponse]

问题 I have a nested array on this link Array Sample I am using code below to parse this, but second and beyond depth it's returning nothing. However tried with recursive function. printAllValues($ArrXML); function printAllValues($arr) { $keys = array_keys($arr); for($i = 0; $i < count($arr); $i++) { echo $keys[$i] . "$i.{<br>"; foreach($arr[$keys[$i]] as $key => $value) { if(is_array($value)) { printAllValues($value); } else { echo $key . " : " . $value . "<br>"; } } echo "}<br>"; } } What I am

问题 Been struggling with this for the last few hours. Trying to build a search function for an array and then spit out a new one containing all arrays that have a keyword. Here is the function I am working with, not sure if this is heading in the right direction or not, it's returning arrays within arrays which is not what I intend. function search_array($array, $needle) { $results = array(); $hasValue = false; foreach ($array as $subarray) { foreach($subarray as $value){ if(strpos($value,$needle

问题 I'm not sure if the history tag is relevant, but feel free to add it. I would presume the reason is historical, which is why I suggest this. Why is it that I cannot declare a function signature such as the following? void foo(int doubly_indexed_array[][]) { ... } which gives $ gcc mem.c mem.c:4: error: array type has incomplete element type Why must you declare one of the dimensions as in the following? void foo(int doubly_indexed_array[][10]) { ... } 回答1: You need to declare the second one

问题 Without a for loop , is there any way to see if a value exists in a multidimensional array ? I found Arrays.asList(*ArrayName*).contains(*itemToFind*) but that will only search the first dimension of the array, and I need to search 2 dimensions. 回答1: I created an 5x5 Integer array and intialized with value i*j. Exists method takes a row number and value to search for. private static Integer[][] myarray = new Integer[5][5]; public static boolean exists(int row, int value) { if(row >= myarray

问题 Hi, I have two arrays like this array ( [0]=>array( [0]=>10, [1]=>Some Name.. ), [1]=>array( [0]=>11, [1]=>Some Name.. ), [2]=>array( [0]=>13, [1]=>Some Name.. ) ) Another array like this array ( [0]=>array( [0]=>13, [1]=>Viewed ) ) How can I merge above two arrays without using any looping? Any php functionality is available for this? I need this kind of an out put array ( [0]=>array( [0]=>10, [1]=>Some Name.. ), [1]=>array( [0]=>11, [1]=>Some Name.. ), [2]=>array( [0]=>13, [1]=>Some Name..
