strict

问题 I'm running Ubuntu + PHP 5.4 and got such error: Strict Standards: Non-static method XTemplate::I() should not be called statically, assuming $this from incompatible context in ... on line 339 And that method looks like this: interface ITemplate { public function I(); } class XTemplate implements ITemplate { public function I() { ... } } And this code is running normal on Windows 7 in XAMPP. I have found only advices to turn off error_reporing, but I need to solve it. Do I need to install

问题 How do I enable MySQL strict mode globally, and have it stay on? I have tried these commands: SET sql_mode = TRADITIONAL; SET sql_mode = ANSI_QUOTES; But they only set the mode for the current session. 回答1: To set the SQL mode at server startup, use: - the --sql-mode="modes" option on the command line, or - sql-mode="modes" in an option file such as my.cnf (Unix operating systems) or my.ini (Windows). ("modes" is a list of different modes separated by commas.) Reference: https://dev.mysql.com

问题 I am using jslint to validate my code. I have "use strict" on all my pages. How can I disable the message "use the function form of 'use strict'" but keep the "Missing 'use strict' statement" warning, so I won't forget to put it on new files? Thanks 回答1: According to Crockford's post, you'll want to wrap everything in a function... (function () { "use strict"; // the rest of your file goes here... }()); You could also use jshint instead, which has a "globalstrict" option that can do exactly

问题 I have a question concerning the definition of strict vs non-strict. The Haskell wiki-book for Laziness (http://en.wikibooks.org/wiki/Haskell/Laziness), under the section "Black-box strictness analysis", makes the following assertion: [Assuming a function f which takes a single parameter.] The function f is a strict function if, and only if, f undefined results in an error being printed and the halting of our program. The wiki contrasts const with id , showing a non-strict and strict function

问题 My PHP script is displaying an error: Strict Standards: Only variables should be passed by reference in C:\....*.php on line 551 The code is below: function trinity_premissions() { global $ACC_PDO, $WEB_PDO, $a_user, $db_translation; $end = false; $res = $WEB_PDO->prepare("SELECT acc_login, gmlevel FROM `accounts_more` WHERE UPPER(acc_login) = :acc"); /* 551 */$res->bindParam(':acc', strtoupper($a_user[$db_translation['login']]), PDO::PARAM_STR); $res->execute(); if ($res->rowCount() == 1) {

问题 When using use strict perl will generate a runtime error on unsafe constructs. Now I am wondering if it is possible to have it only print a warning instead of causing a runtime error ? Or is use warnings (or -w) warning about the same issues ? 回答1: I'm gonna take a stab at guessing the real motivation here. Feel free to tell me if I guessed wrong. I suspect your trying to tackle a large, older code base and would like to enable strictures but you were hoping first to get a sense of where the

问题 This question already has answers here : How can I use a variable as a variable name in Perl? (3 answers) Closed 3 years ago . Basically, I would like to grab the contents of a variable named in a dynamically generated string, but all efforts to accomplish this in strict mode have failed. There are several posts about similar problems, but none seem to have solutions that have worked for me. This is what I want to do: # Fields: $q1 = "ex. data 1"; $q2 = "ex. data 2"; $q3 = "ex. data 3"; $q4 =

问题 when running code like this: use strict; print Dumper "something"; nothing is printed out and no error occurs during compile and runtime. Why does this happen? Why doesn't strict prevent this code from running? Why is there no error at runtime, even though Dumper is unknown? I know it produces a warning when those are explicitly enabled, but I'm interested why is this code considered "correct" in any way. 回答1: One of the valid syntaxes for print is print FILEHANDLE LIST In your program Perl

问题 I have been wondering about this a lot, but I haven't been able to find anything about it. When using the seq function, how does it then really work? Everywhere, it is just explained saying that seq a b evaluates a , discards the result and returns b . But what does that really mean? Would the following result in strict evaluation: foo s t = seq q (bar q t) where q = s*t What I mean is, is q strictly evaluated before being used in bar ? And would the following be equivalent: foo s t = seq (s

问题 Simple: I want to disable/overwrite alert() . Can I do this? More importantly, is it right to do this? What about strict mode? 回答1: Yes, you can disable or overwrite alert() . No, it's not right to do it, except in some bizarre and limited situations. Disable: window.alert = function() { }; Override: window.alert = function(text) { /* do something */ }; 回答2: Yes you can, it's your choice. You could also store the original 'alert': window.nativeAlert = window.alert; window.alert = function(val
