syntax standards question

[lc21]

Hi is it standard when using PHP to use single quotes aroud the center attribute, I am aware that it can be done in other ways but I am just wondering if there is a standard or is the following method ok?

 

<?php
echo "<p align='center'></p>";

?>

<?php
echo '<p align="center"></p>';
?>

<?php
echo "<p align=\"center\"></p>";
?>

Thanks for the reply are both methods ok to use or is there a prefered standard?

[The Little Guy]

they are both fine to use.

 

basically it is personal preference. I usually go with the first way.

<?php
echo "<p align='center'><a href='$path'>link</a></p>";
?>

 

In the event of a variable being encorporated into the code is the above method accepated for having the hyperlink url in a variable?

Yes, but I prefer to put curly brackets around the variable (see below example). That'll allow you to use arrays in it too, I don't think it will otherwise. Also note that double quotes are required if you need it to parse variables, line breaks (\n), tabs (\t) etc.

 

<?php
echo "bla bla {$var['something']}";
?>

I think this is more of an XHTML standards question. Every documentation that ive seen uses double quotes for enclosing the attributes of a tag. On the other hand, they all tend to just say that the attribute value must be enclosed in quotes(they do not specify double quotes) - but as i say, they all use double quotes in their examples.
