php-5.4

问题 So, I am running a long-running script that is dealing with memory sensitive data (large amounts of it). I (think) I am doing a good job of properly destroying large objects throughout the long running process, to save memory. I have a log that continuously outputs current memory usage (using memory_get_usage()), and I do not notice rises and drops (significant ones) in memory usage. Which tells me I am probably doing the right thing with memory management. However, if I log on to the server

问题 I was wondering if someone may know an alternative to the PHP 5.6.x and higher ... operator (or splat operator I believe its called). What i'm currently doing in my PHP 7 version is: $this->callAction( ...explode('@', $this->routes["authControllers"][$this->routes["uri"][$uri]]) ); The callAction() function takes 2 parameters callAction($controller, $action) but now I need to downgrade the code to PHP 5.4.17. 回答1: Though the splat operator ... is similar to call_user_func_array() : call_user

问题 I'll be working soon on a project and I just wanted to ask this before. The project is on symfony 2.8 with php 5.4. The goal is to upgrade symfony to 3.4 (maybe 4.x later) and php to 7.x (probably 7.2). So here is my question : is there a better order to do this? Php 5.4 to 7.2 first or symfony 2.8 to 3.4 (or it doesn't matter)? Thanks for your advices. 回答1: First of all – you won't be able to run Symfony 3.4 project on PHP5.4. As of 2018-11-26 The latest Symfony ^3.4 version is v3.4.19 which

问题 How do you use custom DQL functions in partials to hydrate query result. Looking for a way to use DQL functions in createQuery or any other doctrine way (nativeSql, QueryBuilder) its not necessary to use partials but it should hydrate my array based on the relationship of tables and it should select only selective fields Following query works fine: $q = $em->createQuery("select " .

问题 There are lots of questions and answers around the subject of valid php syntax from var outputs, what I am looking for is a quick and clean way of getting the output of var_export to use valid php5.4 array syntax.
