Using " and ' in PHP [help]

[akulion]

hi

Ok to my understnding when you use " (double quotes) to echo out a statement in PHP, you can call functions / variable etc without having to close the echo statement as in the case of the ' (single quotes) yea?

What I want to know is that in the code below for recent topics (mod version) the arrays send values - would these need to be in '' or should they be taken out?

Currently I get an error when trying to run this code:

Code Select Expand



global $scripturl;
$what=ssi_recentTopics('10', array('13','58'), 'array');

echo "<table border='0' width='100%' cellspacing='1' cellpadding='4' class='bordercolor'>";
echo "<tr class='catbg3'><td valign='middle'>Subject</td><td valign='middle'>Board</td><td valign='middle'>Poster</td><td valign='middle'>Time</td></tr>";

foreach ($what as $topic)
  {
    echo "<tr><td class='windowbg' valign='middle'>$topic['link']";
    // Is this topic new? (assuming they are logged in!)
    if (!$topic['new'] && $context['user']['is_logged'])
      echo "<a href='$scripturl?topic=$topic['topic'].from$topic['time']#new><img src='$settings['images_url']/$context['user']['language']/new.gif alt='$txt[302]' border='0' /></a>";
      echo "</td><td class='windowbg2' valign='middle' >$topic['board']['link']</td>";
      echo "</td><td class='windowbg2' valign='middle' >$topic['poster']['link']</td><td class='windowbg2' valign='middle' >";
      if ($settings['images_url'] != $settings['theme_url'] . '/images' || file_exists($settings['theme_dir'] . '/images/icons/last_post.gif'))
      echo "<a href='$topic['href']'><img src='$settings['images_url']/icons/last_post.gif alt='$txt[111]' title='$txt[111]' border='0' style='float: right;' /></a>";
      echo "<span class='smalltext'>$topic['time']</span></td></tr>";
  }

echo "</table>";

You can use either, but always remember to escape the 'opposite' quote, or simply escape them all. SMF usually uses single quotes because it's slightly faster I think.

ah I see

ok then ill try the same code above using single quoted echo statements and see how it goes Thanks

[akulion]

oh wow!

its easier too using single quotes

got it working in 3 mins!

thanks again

[eldacar]

If you use single quotes you can put the variables straight into the text though, you have to do something like

Code Select Expand

echo 'text yay', $context['data'], 'more text yay';

[akulion]

yea thats the problem i was having with double quotes - or maybe i was doing it wrong because this was giving errors:

Code Select Expand


echo" text yay $context['data'] more text yay";


but doing the single quoted echo worked just fine - so switched over to it

yall want the tutorial? lmao double quotes allow the use of vars inside the echo string but accent does not you have to come out of accent put var in than go back into accent.

I'll find you that tut

and lesson 2 operators in php lol

aahhh so I would have had to use:

Code Select Expand


echo" text yay {$context['data']} more text yay";


with the {}

cool! Thanks for the site- i didnt even know it existed
