php, php Smybolic, php AST

PHP is an interesting language because it is very similar JSX in many ways. I would like to create a table comparing php 5 to php 7 but it appears PHP5.6 is now around 7% market share but this says 23% market share. tutorialspoint PHP7. PHP7 is pretty straight forwardish. I want to create a simple library that is both valid JS and allows of pasting of HTML code. PHP7 library that lets you use the most common javascript functions. php has special functions for utf-8 support. Detecting PHP

There is no operator overloading in php., but you can sort of extend the functions by making a class with __invoke. Arrays and Srings can not be subclassed effectively because gettype with no technique will return the correct value. To deal with utf-8 in php you use the mbstring functions and mysql uses `utf8mb4` for character set. I need to break down the PHP functions and wordpress internal php functions.

function sr_length($a){return count($a);}
function s_indexOf($a){return strpos();}
function mb_str_split(str){print_r(mb_split("\s", "hello world") );}
function mb_strlen(str){str.length}
mb_strpos("test","t",int $offset = 0);
mb_strrchr(
    string $haystack,
    string $needle,
    bool $before_needle = false
 );
mb_strrichr(
    string $haystack,
    string $needle,
    bool $before_needle = false,
    ?string $encoding = null
);
echo mb_substr_count("This is a test", "is"); // prints out 2
mb_substr(
    string $string,
    int $start,
    ?int $length = null,
    ?string $encoding = null
);
mb_strstr(
    string $haystack,
    string $needle,
    bool $before_needle = false,
    ?string $encoding = null
);

$values = [65, 63, 0x20AC, 128024];
foreach ($values as $value) {
    var_dump(mb_chr($value, 'UTF-8'));
    var_dump(mb_chr($value, 'ISO-8859-1'));
}

mb_strtoupper
mb_strtlower

if (preg_match('/1999/', $s)) {
  echo "party!\n";
}
if (s.match(/1999/)) {
  console.log('party!');
}

$s = "do re mi mi mi";
$s = preg_replace('/mi/', "ma", $s);

s = 'do re mi mi mi';
s.replace(/mi/g, 'ma');

a.filter((x) => x > 1)	

array_filter([1, 2, 3],
  function ($x) {
    return $x>1;
  })

array_reduce([1, 2, 3],
  function($x,$y) {
    return $x + $y;
  }, 0)

a.reduce((m, o) => m + o, 0)	

Unlike preg_replace, mb_ereg_replace doesn't use separators
$data = preg_replace("/[^A-Za-z0-9\.\-]/","",$data);
