Unfortunately, the documentation is not correct. If the string starts with valid numeric data, this will be the value used. Otherwise, the value will be 0 zero. The documentation says that if the string contains a "e" or "E" character, it will be parsed as a float, and suggests to see the manual for strtod for more information.

A binary exponent consists of a 'P' or 'p', followed by an optional plus or minus sign, followed by a nonempty sequence of decimal digits, and indicates multiplication by a power of 2. However, PHP uses the locale while converting numbers to strings. With strtod, the current locale is also used to choose the space characters, I don't know about PHP. If you want a parsed variable surrounded by curly braces, just double the curly braces: In this case, that applies only to the inner braces. The outer ones are not escaped and pass through directly.

Use caution when you need white space at the end of a heredoc. Not only is the mandatory final newline before the terminating symbol stripped, but an immediately preceding newline or space character is also stripped. I commented on a php bug feature request for a string expansion function and figured I should post somewhere it might be useful: I don't know if there's ever a truely safe way to use eval on the web, I'd rather not use it.

You may use heredoc syntax to comment out large blocks of code, as follows: Also useful if you wish to embed Perl-like Plain Old Documentation; extraction between POD markers is left as an exercise for the reader. Note there is a performance penalty for this method, as PHP must still parse and variable substitute the string. If you want to use a variable in an array index within a double quoted string you have to realize that when you put the curly braces around the array, everything inside the curly braces gets evaluated as if it were outside a string. Here are some examples: I recently discovered the joys of using heredoc with sprintf and positions.

Useful if you want some code to iterate, you can repeat placeholders.

I like the state of Oregon I picked: A word of caution about taking the use of single and double quotes shown here too literally. A convention is established early on, referring to double-quotes " and semicolon ; for example, so the later section about concatenation using the '. This tripped me up until I mentally reparsed it as the dot. Heredoc literals delete any trailing space tabs and blanks on each line.

This is unexpected, since quoted strings do not do this. This is probably done for historical reasons, so would not be considered a bug. I noticed that the documentation does not mention that when you have an XML element which contains a dash - in its name can only be accessed using the bracelets notation.

For example: Hope this helps, Denis R.

If you read carefully, you will notice this, in the 1st sentence of the warning about heredocs: It is refering about semicolons But wait, there is more: So, if you put a "real" semicolon at the end of these examples: After all, a heredoc or a nowdoc is simply a string. You should read more carefully the documentation first before saying any comment.

About serious questions: I didn't read all comments here, but you can run functions inside strings and heredocs. So you want to get the last character of a string using "String access and modification by character"? I encountered the odd situation of having a string containing unexpanded escape sequences that I wanted to expand, but also contained dollar signs that would be interpolated as variables. Some muddling through docs and many obscenties later, I produced the following, which expands escape sequences in an existing string with NO interpolation. This can be handy in constructing exec calls with complex data to be passed to other programs.

Regarding the lack of complex expression interpolation, just assign an identity function to a variable and call it: When there are a lot of very simple value transformations made just for display purposes, it can de-clutter code. A note on the heredoc stuff.
