Hi monks,

Maybe I'm used to Perl in respect to $ for scalars, @ for arrays and % for hashes.

I'm reading up on PHP and I come across code such as:

while($element = each ($fruit)) {
  echo $element['key'];
  echo '-';
  echo $element['value'];
  echo '<br />';
}
[download]

which is equivalent to Perl's

while (($key, $value) = each (%fruit) {
  print $key;
  print '-';
  priint $value;
  print '<br />';
}
[download]

When I read Perl code, the % immediately tells me that I'm looking an associative array. In contrast, all variables in PHP are prefixed with $, which I find rather unhelpful.

If I'm not wrong, Ruby has none of those and I imagine that it must be a lot more cryptic, because the variables can read like function words:

for x in 0...c.length do print c[x], " " end
[download]

Which are the variables and which are the function words?

What are your views?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
