问题 I have following arrays. Array ( [0] => Array ( [0] => Cash [1] => 91.16 ) [1] => Array ( [0] =>Credit [1] => 61.48 ) ) I want to do something like this . foreach ($value as $values) { // Where $values is the above array . I want to traverse array dynamically and put if condition . if($values[0][0] != "Cash") echo "Cash"; } The above code does not working . Please help me on this . How can I place if condition dynamically inside foreach loop. 回答1: Is this what you mean? foreach ($values as

问题 I have a code like this. <ul> <?php foreach (getUserMainMenus($get_user_id) as $get_main_menu): ?> <li class='has-sub'><a href='#'><span><?=$get_main_menu['menu_name']; ?></span></a> <ul> <?php foreach (getUserChildMenu($get_main_menu['m_id'], $get_user_id) as $sub_menu): ?> <li class='has-sub'><a href='<?=$sub_menu['menu_url']; ?>'><span><?=$sub_menu['menu_name']; ?></span></a> <ul> <?php foreach (getUserSubChildMenu($sub_menu['m_id'], $get_user_id) as $sub_sub_menu): ?> <li class='has-sub'>

问题 I have an HTML form that allows the user to select from a list of employees. The variable is '$empfullname.' However, I also want them to be able to select an 'All' option and if selected it should take the first employee and run the PHP script, then take the next, and so on and so forth. However, the code I have right now if 'All' is selected just displays the first employee in the table and stops. Maybe I need a foreach in their as well? Any help is greatly appreciated. Thanks. if (

问题 I am working on generating a 40 bit length pulse train. I also must be able to adjust the frequency. I tried to make a new low frequency clock and i make a new counter which counts on it's rising edges and give an high output and terminating after 40 bit. It's not working. I tried some other methods. They are not, too. For example; library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.NUMERIC_STD.all; entity con40 is port(clk:in std_ulogic; q:out std_ulogic); end entity con40; architecture

问题 I'm working on a code in eclipse with swing and I have a long-ish if, else function that I'm having trouble with. So, I kind of forgot about nested if, else functions and made all the if's separate, which of course only brings back the last if as true. I want the else function to take into consider multiple constraints, but how do I do this when each "if" has its own dialog message that pops up? I tried to just make it one long if function with &&'s and a single dialog message, which would

问题 for each pixel, do if R>90 & R>G & R>B classify the pixel as **Healthy** else classify the pixel as non-healthy I am trying to implement an algorithm which reads a skin lesion image and after extracting the R, G, and B values, it classifies the lesion into healthy skin or non-healthy skin based on the if condition However, when I try to implement it, only the non-healthy skin array is getting updated inside the for loop and the healthy skin array remains zero. I do not know how to overcome

问题 I am trying to program a decision tree to allow customers to order goods based on their input. So far, I have devised a nested if-elif conditional structure to decide if customer want to order --> what order category --? what product from that category --> what size --> what quantity Below is a sample of the structure which would become more nested if I continued the process. My question is, could this be implemented via a decision tree data structure, e.g. a dictionary which gathers user

问题 For my question above, I'm terribly stuck. So far, the code I have come up with is: def count_bases(): get_user_input() amountA=get_user_input.count('A') if amountA == 0: print("wrong") else: print ("right",amountA) def get_user_input(): one = input("Please enter DNA bases: ") two=list(one) print(two) My line of thinking is that I first: 1. Ask user to enter the DNA bases (ATCG) 2. Change the user input into a list 3. Going back to the main (count_bases) function, I count the number of 'A',

问题 What I want to do is When I enter all my information (for client ID 199 in the picture) In my account being submit it, it goes into the database. BUT I want it to change to something and so i added an if statement Here the code im adding to the existing code already at the BOTTOM of the code if ($vpr_clid == 199) { $vpr_cl_name = "Shelley Madsen And Associates"; } if the ($vpr_clid = 199) i want the clname to be "Shelley Madsen And Associates" then what is show in the table below instead of
