foreach

问题 The following code automagically finds the highest price on a page: $vw_link = get_field('shop_link'); $ch = curl_init($vw_link); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $cl = curl_exec($ch); $dom = new DOMDocument(); @$dom->loadHTML($cl); $xpath = new DOMXpath($dom); $price = $xpath->query("//span[@class='price']"); foreach($price as $value) { $vw_array[] = floatval(str_replace('$', '', $value->nodeValue)); update_field('shop_price',max($vw_array)); } What would be the best thing

问题 In SSIS I am using a Foreach loop container to loop through a list of files. My project works fine in locally - it finds the files, but when I deploy to SSMS and run it, it gives the error: The for each file enumerator is empty. The for each file enumerator did not find any files that match the pattern, or specified directory was empty. The directory I am pointing to is a network location I have permissions on this directory. Has anyone experience this issue before? 来源： https://stackoverflow

问题 Consider the following C# code. string[] stringArray = new string[10]; foreach (string s in stringArray) s = "a new string"; // Compiler error - Can't assign to foreach iteration variable Now consider the following valid C++/CLI code. array<String^>^ stringArray = gcnew array<String^>(10); for each(String^% s in stringArray) s = "a new string"; When foreach is used with array type, compiler translates it into normal for loop. This implementation is same for C# and C++/CLI. So I wonder if C++

问题 How can I export the global environment for the beginning of each parallel simulation in foreach? The following code is part of a function that is called to run the simulations. num.cores <- detectCores()-1 cluztrr <- makeCluster(num.cores) registerDoParallel(cl = cluztrr) sim.result.list <- foreach(r = 1:simulations, .combine = list, .multicombine = TRUE, ) %dopar% { #...tons of calculations using many variables... list(vals1, vals2, vals3) } stopCluster(cluztrr) Is it necessary to use

问题 In PowerShell v2, I'm trying to add only unique values to an array. I've tried using an if statement that says, roughly, If (-not $Array -contains 'SomeValue'), then add the value, but this only ever works the first time.

In my example there is 4 names but in reality i will be doing a lot of inserts and updates in a project im working on that will have 20 or so fields. I like this approach for its clarity but obviously when your talking 20 fields or more it does take a lot of real estate. Lets look at my code first. Here are the functions it uses: // prepare the
