In PHP, a null byte in a string does NOT count as the end of the string, and any null bytes are included in the length of the string. For example, in PHP: strlen( "te\0st" ) = 5 In C, the same call would return 2.

HEREDOC isn't that bad, the indenting thing is a pain but not that much of one. This is usually what I do for strings with significant line breaks (like SQL statements).

Fuck line lengths and just have one long string. It's 2015, we're not on TRS-80s anymore. This is what I do most of the time.

May 3, 2015The state of PHP unicode in 2019
PHP doesn't really manage unicode at all. They tried, and that was one of the factors that led to PHP 6 never becoming a thing. So instead, they decided to not have unicode strings at all - you only get byte arrays (which you may write as string literals). If you want actual strings, you have to implement most of it yourself, PHP only gives you a couple of primitives that you can use to operate on various string encodings (including utf-8 and other Unicode encodings) at the byte array level. So basically much the same deal as in C, except that PHP is supposed to be a high-level programming language that takes care of these things for you. More on reddit.com
