RE: how call a variable in a text

["David Murphy" <david@xxxxxxxxxxxxxxxxx>]

True however   K.I.S.S  would say , if  you can use it  like

 

 

echo “This is a statement {$Blah}.”;

echo “This is also a statement {$objBlah->BlahString}.”;

echo “This is also a statement {$tBlah[‘BlahKey’]}.”;

 

 

You should do it so you are always using the same expected format, cleaner for readability and training other people to understand how you code.

 

 

This is my personal thoughts on it, everyone has their own prefs.

You need to use double quotes (or HEREDOC) if you want PHP to replace $variable with its value in the string:

$message="

<b> There is a text $variable  trial. </b> ";

or

$message = <<<MESSAGE

<b> There is a text $variable  trial. </b> MESSAGE;

The {} only become really useful when you're trying to reference arrays within a string:

$var = array('great', 'boring');

$text = "this is {$var[0]}.";

Without the curly braces, PHP wouldn't be able to figure out whether you wanted the end string to be 'This is great.' or 'This is [0].' despite the variable itself clearly being an array.
