  php netbeans character-encoding whitespace file-encodings
  I’m editing the functions.php file of a WordPress theme and whenever I edit it, even when the edit is adding a single space the server returns error:Parse error: syntax error, unexpected ‘}’ in /theme/functions.php on line 1 This is where I add the single space:<?php load_theme_textdomain(‘theme’, get_template_directory() . ‘/languages’); <- I added a single space hereand everything dies after that. This is not a consistent error, as it goes away after I replace the whole functions.p

  php unit-testing sockets
  Greetings Stackoverflowers,I have an application in which a communication abstraction layer exists. Each implementation in this layer, called a connector, provides my application with a way of exchanging data with a connected peer (e.g.: through HTTP, TCP sockets, UDP sockets, etc.).Per example, I have a Connector_Tcp class that implements methods such as read, write, open and close.I need to write a unit test for that class. I know that unit tests should have as less dependencies as possible. U

  php tags fgets
  I’m using fgets to read a text file that contains field names delimited with the “<” and “>” characters. It seems like fgets is seeing these field names as tags and stripping them. I thought that only fgetss stripped tags and that fgets should allow this. I’m testing this with the following code:<?php $handle = @fopen(“Test.txt”, “r”); if ($handle) {while (($buffer = fgets($handle, 4096)) !== false) {echo $buffer;}if (!feof($handle)) {echo “Error: unexpected fgets() fail\n”;}fclose($handle

  php
  I’m not sure how simple is this to solve, but I assume I’m doing something wrong. I’m new to PHP, so bear with me, please.When I started learning PHP, I always placed all my project files into the same folder along with index.php and thus included everything like this:<?php include(‘./translation.php’); ?>Later on in the process of learning as I gained experience and my skill increased, I had to start using folders and place my files into sub folders. I ended up successfully including my f

  php string utf-8 comparison
  I’m trying to compare two string lets say Émilie and Zoey. Well ‘E’ comes before ‘Z’ but on the ASCII chart Z comes before É so a normal if ( str1 > str2 ) Won’t work. I tried with if (strcmp(str1,str2) > 0) still don’t work. So i’m looking into a native way to compare string with UTF-8 characters.

  php javascript html validation dom
  I’m looking for something like http://validator.nu/, I’ll be validating html input ( string ) and I want to notify the user if there are any missing end tags, whether a certain element can’t have a certain attribute, things of that nature ( HTML 4.01 Strict validation basically ).Sidenote: I won’t be dealing with XML/DTDs, and I don’t want to correct the user input like how http://htmlpurifier.org/ does it.

  php
  I have a bit of a general dissatisfaction about the way passing by reference works in PHP, coming from a Java background myself. This might have been talked about before on SO, so I’m sorry if this might seem redundant.I’m going to give a code example to make things clear. Say we have a Person class:<?phpclass Person {private $name;public function __construct($name){$this->name = $name;}public function setName($name){$this->name = $name;}public function getName(){return $this->name;

  php logging
  Well…I do know it’s good to log errors when the website is in production and error reporting is off. But what should I actually log? I can’t log all errors, so I should to choose some most errors-probable places in the code and call the function with some message to log this. Should I use try-catch to do this? And is it actually the best way to do this?

  php validation date datetime language-agnostic
  I’m working on date validation for a validation library. A date format and a variable containing the date to validate will be supplied to the library.$validator->validate( $_POST[‘date’], ‘m/d/y’ );It’s pretty easy to do basic validation with DateTime::createFromFormat()if ( DateTime::createFromFormat( $format, $date ) !== false ) {// “valid” date }My issue is that with this method invalid dates such as 23/23/23 pass because the DateTime class will shift the date and set it to 2024-11-23.

  java regex string split
  I’m making a text based dice roller. It takes in strings like “2d10+5” and returns a string as a result of the roll(s). My problem is showing up in the tokenizer that splits the string into useful parts for me to parse into information.String[] tokens = message.split(“(?=[dk\\+\\-])”); This is yielding strange, unexpected results. I don’t know exactly what is causing them. It could be the regex, my misunderstanding, or Java just being Java. Here’s what’s happening: 3d6+4 yields the string array

  c++ truncation
  I have just joined a team that has thousands of lines of code like:int x = 0; x=something(); short y=x; doSomethingImportantWith(y); The compiler gives nice warnings saying: Conversion of XX bit type value to “short” causes truncation. I’ve been told that there are no cases where truncation really happens, but I seriously doubt it. Is there a nice way to insert checks into each case having the effect of: if (x>short.max) printNastyError(__FILE,__LINE); before each assignment? Doing this ma

  windows logging console truncation
  We build complicated console-based tools that produce a lot of commentary on the console. These tools process a lot of data and so runs are expensive and we don’t like to do them more often than necessary, especially during testing where we already have to run them repeatedly. During such tests, we often log the result to a file to capture this commentary for inspection:C:> [ourcommand] >log.txt When the application runs to completion, this works great.If the application crashes (illegal mem

  Is it possible, prior to converting a string from a charset to another, to know whether this conversion will be lossless?If I try to convert an UTF-8 string to latin1, for example, the chars that can’t be converted are replaced by ?. Checking for ? in the result string to find out if the conversion was lossless is obviously not a choice.The only solution I can see right now is to convert back to the original charset, and compare to the original string:function canBeSafelyConverted($string, $from
