mysql - How to fetch all the data from database in php -

-

यह मेरा कोड है: 

  & lt;? Php / *** mysql hostname * ** / $ होस्टनाम = 'लोकलहोस्ट'; / *** mysql उपयोगकर्ता नाम *** / $ username = 'root'; / *** mysql पासवर्ड *** / $ पासवर्ड = ''; {$ Dbh = नया पीडीओ ("mysql: host = $ hostname; dbname = नमूना", $ उपयोगकर्ता नाम, $ पासवर्ड) का प्रयास करें; / *** एक संदेश को गूंजते हुए कहते हैं कि हमने जुड़ा हुआ है *** / गूंज 'डेटाबेस से जुड़े & lt; br / & gt;'; $ Sql ​​= "नमूना से चयन करें"; $ Stmt = $ dbh- & gt; क्वेरी ($ sql); $ परिणाम = $ stmt- & gt; प्राप्त करें (पीडीओ :: FETCH_ASSOC); विदेशी मुद्रा ($ कुंजी के रूप में $ परिणाम = & gt; $ val) {echo $ key '-'। $ Val। '& Lt; br / & gt;';; } $ Dbh = नल; } पकड़ (PDOException $ ई) {गूंज $ e- & gt; getMessage (); }? & Gt;

अब मैं PHP सीख रहा हूं, मुझे पोडो कनेक्शन को सम्मिलित करने के बारे में जानना चाहिए, डाटाबेस से फ़ेच डेटा अपडेट करें। मैंने इस लिंक को संदर्भित किया है

अब मुझे पहला कॉलम मान मिला .. क्या मुझे पता है कि डेटाबेस से सभी रिकॉर्ड कैसे लाएं?

अग्रिम धन्यवाद

आप बस - & gt; प्राप्त कर सकते हैं; all () इस विधि के साथ:

<पूर्व> $ परिणाम = $ stmt- & gt; प्राप्त करें सभी (PDO :: FETCH_ASSOC); // सभी पंक्तियों को विदेशी मुद्रा देता है ($ का परिणाम के रूप में $ कुंजी = & gt; $ पंक्ति) {echo $ row ['id'] '-' $ पंक्ति ['column_name'] '& Lt; br / & gt;'; // ^ कॉलम का नाम, यह एक बहुआयामी रिटर्न देता है}

सिडेनोट: इसकी अभी भी अंदर एक सरणी है, इसलिए आपको उस कॉप के अनुक्रमण को एक्सेस करना होगा foreach।

या यह भी पसंद है: 

  जबकि ($ पंक्ति = $ परिणाम- & gt; प्राप्त करें (पीडीओ :: FETCH_ASSOC)) {$ पंक्ति ['आईडी'] गूंज करें '-' $ पंक्ति ['कॉल 1'] '& Lt; br / & gt;'; }

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport. I am running a new browser and trying different people so remove it from the API / URL, and just use the localhost: (potter) / signaller / Chat

Camel ProducerTemplate possible memory leak -

-
To some degree, this is a bit of a shot in the dark, but we have a process that is dramatically slow One day's course we have found that all the things running on the fuses begin to draw, but when we are running a specific process, JPPropellers are going on, I have found that the increase in magnetic usage increases over time. . Org.apache.camel.ProductTemplate.Send So my main question is, is the way in which the manufacturer product is being used here which is wrong / can this be a problem? exchange foo = new DefaultExchange (getCamelContext (), ExchangePattern.InOnly); Foo.getIn () setBody (obj). Root R = Exchange .getContext (). GetRoute ("do_something_fun"); Creator Template Template = exchange.getContext () CreateProducerTemplate (); Template.send (r.getEndpoint (), foo); Generally, you should not create a productive template on each request as described here: / P> However, because I do not have a complete picture of your application, so you can cr...

javascript - Adhering to a max length setting with jshint -

-
I get several recommendations to compile a maximum of 80 characters when writing javascript, e.g. Google, NPM, Node. JS, Crockford In some cases, though, I do not think how best to do this. MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase', function (mistake, database) {if (err)} {throw error;} db = database;}); This will throw a jshint warning because it exceeds 80 characters. Now, do you choose to ignore the warning in this example, or instead choose an option for a solution like MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase' , Function (err, database) {if (err) {throw error;} db = database;}); If you can reuse the url variable So, great option if this is a shot, as is often such a call, I would probably do something like this ... / * jslint sloppy: true, white: true, browser: True, maxlen: 80 * / / * global mongo client * / var dbarhh, db; DbErrHand = function (mistake, database) {if (err) {throw error; } ...
