heredoc

I'm new to PHP and don't understand what the point of <<<_END is. Could someone please explain when this should be used? I've looked at various examples and they all seem to have HTML embedded within them. But I can use HTML without the <<<_END tags, so why should I use them? I tried searching the manual, but I keep finding the end() method for arrays. It's the start of a heredoc . you can do: $data = <<< _END You can write anything you want in between the start and end _END; _END can be just about anything. You could put EOF or STUFF . as long as you use the same thing at the start and the

This question already has an answer here: Java multiline string 39 answers For JAVA development I need writing to a files with strings like "\r\t\n <>", because from Java I want writing a PHP file. If you can't understand look at this example: BufferedWriter buffW = new BufferedWriter(fileW); buffW.write("<?php\n\n\tclass MyClass {\n\tpublic function test()\n}\n}\n?>"); This is mess a code, I want to write a clean such as PHP can do, but can't find on Java alternative way as example: <?php $mystring = <<<EOT This is some PHP text. It is completely free I can use "double quotes" and 'single

I've already found some solutions, but can't know what happened... Example 1: <?php echo <<< EOD test EOD; Example 2: <?php echo <<< 'EOD' test EOD; Output 1,2: PHP Parse error: syntax error, unexpected end of file, expecting variable (T_VARIABLE) or heredoc end (T_END_HEREDOC) or ${ (T_DOLLAR_OPEN_CURLY_BRACES) or {$ (T_CURLY_OPEN) Example 3: <?php echo <<< EOD test EOD; ?> Example 4: <?php echo <<< 'EOD' test EOD; ?> Example 5: <?php echo <<< EOD test EOD; 'dummy'; Example 6: <?php echo <<< 'EOD' test EOD; 'dummy'; Output 3,4,5,6: test You probably have spaces after the terminator in your

Is this possible at all and how? Update: I need this because I create a file both from dynamic and static data. Use case: I have a test directory. Each C file produces a test executable. With SRCS = $(wildcard [a-z]*.c) I can add new tests as needed and make will find the new tests, compile, run and valgrind them. I also use git. I would like .gitignore to include the executables. So there. How to create .gitignore and include static data, i.e. the files I want to be ignored ( *.o and depend ) and also the executables dynamically? Another GNU Make solution. You can do it using the define and

How do you use define within a heredoc ? For example: define('PREFIX', '/holiday'); $body = <<<EOD <img src="PREFIX/images/hello.png" /> // This doesn't work. EOD; taken from the documentation regarding strings DEFINE('PREFIX','/holiday'); $const = PREFIX; echo <<<EOD <img src="{$const}/images/hello.png" /> EOD; if you have more than 1 constant, variable usage would be difficult. so try this method define('PREFIX', '/holiday'); define('SUFFIX', '/work'); define('BLABLA', '/lorem'); define('ETC', '/ipsum'); $cname = 'constant'; // if you want to use a function in heredoc, you must save function

Are there any good ways to work with blocks of text (Strings) within Java source code? Many other languages have heredoc syntax available to them, but Java does not. This makes it pretty inconvenient to work with things like tag libraries which output a lot of static markup, and unit tests where you need to assert comparisons against blocks of XML. How do other people work around this? Is it even possible? Or do I just have to put up with it? While you could use certain formatters to convert and embed any text file or long literal as a Java string (e.g., with newline breaks, the necessary
