Regex extract string between 2 curly braces

And for the second operations you need it could be something this way:

$str = "Dear {{name||email}}, You are being invited for the following event: {{event}}. Regards, {{author}}";

// $data['name'] = 'John Doe'; 
$data['email'] = 'JohnDoe@unknown.com'; 
$data['event'] = 'Party yay!'; 
$data['author'] = 'Kehke Lunga';

$pattern = '/{{(.*?)[\|\|.*?]?}}/';

$replace = preg_replace_callback($pattern, function($match) use ($data)
{
    $match = explode('||',$match[1]);

    return isset($data[$match[0]]) ? $data[$match[0]] : $data[$match[1]] ;
}, $str);

echo $replace;

Basically by editing the '$pattern', and then find the correct logic needed inside the callback.

Extracting substrings between curly brackets inside a string into an array using PHP

You could use this regex to capture the strings between {}

\{([^}]*)\}

Explanation:

\{ Matches a literal {
([^}]*) Capture all the characters not of } zero or more times. So it would capture upto the next } symbol.
\} Matches a literal }

Your code would be,

<?php
$regex = '~\{([^}]*)\}~'; 
$string = "www.example.com/?foo={foo}&test={test}";
preg_match_all($regex, $string, $matches);
var_dump($matches[1]);
?>

Output:

array(2) {
  [0]=>
  string(3) "foo"
  [1]=>
  string(4) "test"
}

(?ms) - turn on multiline (m, makes ^ and $ match start and end of lines respectively) and dotall (s, makes . also match line break chars that it does not match by default) modes
^ - start of a line
myFunction\\(\\{ - a literal myFunction({ text
.*? - any zero or more chars, as few as possible
^ - start of a line
\}\) - a literal }) text
$ - end of a line.
