April 10, 2015Emojis are breaking our json decodes. Help.
Another thing to watch out for is MySQL if you are using it to store the utf8. The 'utf8' encoding is only 3 bytes. It truncates a string silently starting at the first 4 byte character. Most (all?) emoji are 4 bytes. You'll need to use 'utf8mb4' encoding. More on reddit.com

Example 1: Variable between single quotes
If you use single quotes everything between them will always be treated as part of the string.
$output .= '<div class="tab-pane" id="' . $type . '">";
Example 2: Variable between double quotes (option 1)
If you have a variable that you want to pass in a string you can just put it in there if you use double quotes and de variable is nog 'touching' the other words. It should always have spaces.
$output .= "<p>i would like to $your_text_here with you.</p>";
Example 3: Escaping quotes in a string
Escaping characters in a string can be done by using a \ (backslash) before the character you want to escape.
$output .= "<div class=\"tab-pane\" id=\"example-id\">";
Example 4: Variable between double quotes without spaces next to it
You can place your variable between {} braces if you use double quotes (option 2)
$output .= "<div class=\"tab-pane\" id=\"{$type}\">";

Your first block is doing string replacements, but then you use the ORIGINAL string, not the replaced one:
$output .= '<div class="tab-pane" id="' . $functionName . '">';
would be more correct. On the second one, you're escaping the ' quotes, which means that you never terminate the string, meaning that the . $type . portion is treated as plaintext within the string, not a PHP concatenation operation. Try
$output .= '<div class="tab-pane" id="' . $type . '">';
instead. note the LACK of backslash escapes.
And of course, you could use a HEREDOC, eliminating any need to escape quotes entirely:
$output .= <<<EOL
<div class="tab-pane" id="{$functioName}">
EOL;
