PHP Variables and if statements

How do I create a variable, that includes and if statement.
<?php
function myFunction() {
$html = '';
  $query = SELECT name FROM Table_Name;
  $data = $data->result_array();
  foreach ($data as $row) {
  $name = $row['name'];
  $html. = '<div class="my-class">Hello:: '.   if($name !="") {echo $name;} else {echo "Stranger";}  .' How are you today?<br /></div>';
  }
return $html;
}

Open in new window


How do I write this part::   if($name !="") {echo $name;} else {echo "Stranger";}

You don't.  You can't put an 'if' statement like that as part of a string.  It needs to go on it's own line.
  $html. = '<div class="my-class">Hello:: ':
if($name !="") {echo $name;} else {echo "Stranger";};  
echo ' How are you today?<br /></div>';

Dave's giving you the right advice here.  Create your variables separately, then test them to see if they are usable, then render the variables in the output strings.  Something like this.  The design pattern plays well with HEREDOC notation.

<?php // demo/temp_rgranlund.php
/**
 * See: http://www.experts-exchange.com/Programming/Languages/Scripting/PHP/Q_28621903.html
 */
error_reporting(E_ALL);

// SET AN ORIGINAL VALUE FOR A DATA ELEMENT
$thing = NULL;

// TEST THE ORIGINAL VALUE AND PROVIDE A SUBSTITUTE IF THE ORIGINAL IS USELESS
$thing
= (!empty($thing))
? strtoupper($thing)
: 'NO USABLE THING'
;

// SHOW THE FINAL VALUE FOR THE DATA ELEMENT
echo $thing;

An alternative approach is to use what's called a ternary operator, along with sprintf(). Also avoids the mess that can can be string concatenation:

$html .= sprintf('<div class="my-class">Hello:: %s. How are you today?</div>', ($name != "") ? $name : "Stranger");
