  php eol
  When is it a good idea to use PHP_EOL? I sometimes see this in code samples of PHP. Does this handle DOS/Mac/Unix endline issues? Most of the PHP I write is for generating HTML, and I use <br/> instead of actual newlines, so haven’t used this constant before.

  php html
  I have strange problem. I am showing these links to interact with them via jQuery and at the very end it always puts symbol “1” for some reason. I’ve looked through all my pages and this was the one that caused it. Can you please explain why and how can I avoid that? It does not matter what I select from cat, 0 or any other viable id… P.S. I know that code is not complete, but this is just draft to make it all work together…<?php$sql = “SELECT * FROM cat WHERE catSubID = 0”;$result = mysq

  php wordpress shortcode
  I just found out that both ‘echo’ and ‘return’ works fine for displaying content from a shortcode function. function foobar_shortcode($atts) {echo “Foo Bar”; //this works fine }function foobar_shortcode($atts) {return “Foo Bar”; //so does this }I just want to know, is there any difference between using either of these? If so what’s the recommended one? I normally use echo in this case; is it okay?

  php mysql
  Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING is the message. It came up from this line of code:$query = (“SELECT * FROM users WHERE user_name = $_POST[‘user_name’] & password = $_POST[‘password’] & user_type = $_POST[‘user_type’]”);Does anyone out there know the meaning of all this? If so, does anyone know how to deal with this?

  php pcntl
  Can anybody tell me why using the pcntl lib on production servers is discouraged? The PHP manual tells very briefly about it, and I’m in a dire need to use this library… Is there another way to do the same thing in php?

  php
  In a legacy php script I found the following line of code:$CacheLite =& ( “string” );Which provokes an error:Parse error: syntax error, unexpected'(‘, expecting T_NEW or T_STRING orT_VARIABLE or ‘$’Is it a mistake or a way of passing by reference or something else I don’t know. Do I have to enable/disable something in my php configuration in order for this to work?

  I’m using PHP 5.3.5 with Fast-CGI.When I try to use gmdate() to set the initial value for a parameter, I get the following error:Parse error: syntax error, unexpected ‘(‘, expecting ‘)’ inMyClass.php on line 3Here’s my code (line 3 is the line where myFunction is declared):function myFunction($myDate = gmdate(‘Y-m-d’)) {// … }Am I doing something wrong? Is this a bug? This also occurs if I do the same thing in a class function.

  Is it possible to re-write the code below, maybe even with an if (result > 0) statement, in just one line (or simply shorter)?// a simple query that ALWAYS gets ONE table row as result $query = $this->db->query(“SELECT id FROM mytable WHERE this = that;”); $result = $query->fetch_object(); $id = $result->id;I’ve seen awesome, extremely reduced constructs like Ternary Operators (here and here – btw see the comments for even more reduced lines) putting 4-5 lines in one, so mayb

  variables scheme racket mutable
  I am new to racket and have run into an instance where I need a mutable numeric variable Below is a function that works thru a string of bits (101011….) and if it encounters a 1 alters a numeric variable named “value” and if it encounters a 0 has to alter that same variable “value”. So when we get to the end of a string we should end up with a total for “value”. (define (implode bstr value)(for ([c (string-length bstr)])(display (string-ref bstr c))(if (eqv? (string-ref bstr c) #\1) (displayl

  python variables pointers
  Variables in python are just pointers, as far as I know. Based on this rule, I can assume that the result for this code snippet:i=5 j=i j=3 print iwould be 3. But I got an unexpected result for me, it was 5.Moreover, my python book does cover this example:i=[1,2,3] j=i i[0]=5 print jthe result would be [5,2,3].What am I understanding wrong?

  java variables
  Was there any reason why the designers of Java felt that local variables should not be given a default value? Seriously, if instance variables can be given a default value, then why can’t we do the same for local variables?And it also leads to problems as explained in this comment to a blog post…

  python variables maya
  I’m writing a script for maya, it’s in python, but this should relate to most things.If I run my script on the left side of a setup the values for translation etc will be something like 29.292 or 68.215.The problem is that the right side is a mirror, so it’s -29.292 or -68.215.I need to check if the symbol ‘-‘ exists within the variable and if so remove it.How do I do this?Thank you

  php .htaccess seo opencart
  How can you customize system URLs in OpenCart? For example, I would like http://example.com/index.php?route=checkout/cart to be displayed as http://example.com/cartI know OpenCart provides SEO URLs for products, categories, manufacturers and information pages, but it doesn’t look like there is anything built-in (at least prior to version 1.5.0) for anything else.
