问题 I need to run a foreach script on a multi-dimensional array. The original JSON is formatted like: { "_links":{ }, "chatter_count":15, "chatters":{ "moderators":[ "moderator1", "moderator2", "moderator3" ], "staff":[ "staff1", "staff2", "staff3" ], "admins":[ "admin1", "admin2", "admin3" ], "global_mods":[ "global_mod1", "global_mod2", "global_mod3" ], "viewers":[ "viewer1", "viewer2", "viewer3" ] } } Having run json_decode to get a PHP data structure, I'm now lost on how to run a foreach loop

问题 I have a nested foreach loop going through 2 arrays with a conditional if - else . When if returns a value the else statement is also still running, why is that? //$global_plugins is an array //$xml_plugins is a string foreach($global_plugins as $key => $global_plugins){ foreach ((array) $xml_plugins as $key2 => $xml_plugins){ if (($global_plugins == $xml_plugins) && ($plugin_verso[$key] == $xml_plugin_version[$key2])){ echo 'Exact match'; }else{ echo 'Fuzzy match'; } } } For this example the

问题 def a: Int = { for(i <- Array(1,2,3,4,5)){ if(i == 3) return i } } The above method will not compile, I get the following error: error: type mismatch; found : Unit required: Int for(i <- Array(1,2,3,4,5)){ ^ The expected behaviour is that the method returns 3. What is wrong with my code? 回答1: That is because your lambda in the foreach does guarantee to return a value. If you provide a default return value it should work. def a: Int = { for(i <- Array(1,2,3,4,5)){ if(i == 3) return i } 0 } 回答2

问题 So I'm trying to find a way to build a function that will replace text with an image if it's an emoticon or with a filtered word if it is a prohibited word. I've taken a look at this code: $smiles = array( 'xD' => 'devil.png', '>:)' => 'devil.png', 'x(' => 'angry.png', ':((' => 'cry.png', ':*' => 'kiss.png', ':))' => 'laugh.png', ':D' => 'laugh.png', ':-D' => 'laugh.png', ':x' => 'love.png', '(:|' => 'sleepy.png', ':)' => 'smile.png', ':-)' => 'smile.png', ':(' => 'sad.png', ':-(' => 'sad.png

I tried use 2 foreach loops but that seems to be out of the question. How could I avoid this problem? Problem occurs here: // Displaying all Book objects from pubs ArrayList. foreach (Book list in pubs) { bookNumber++; // Count books from the begining. // Displaying and formating the output // in
