Question

I have a few strings

Computer Stations
Monitors
Indian Reserve

How do i replace spaces in a variable with carriage returns "\r"? How can I determine if a replacement was made so I can add a CSS class in my output.

My PHP is below and basically for CSS purposes i need to force a carriage return on two words and if the string is a single word then give the class “single” so i can style it differently…any ideas

$key "Computer Stations"
echo "<li><a href=\"#\" class=\"cat cat-btn  lf\">{$key}</a></li>";
$key "Monitors"
echo "<li><a href=\"#\" class=\"cat cat-btn single lf\">{$key}</a></li>";
$key "Indian Reserve"
echo "<li><a href=\"#\" class=\"cat cat-btn  lf\">{$key}</a></li>";

Answer 1

Following code will replace all spaces with return symbol ("\r") and if there isn’t any, set variable $class to "single".

$newString = str_replace(" ", "\r", $oldString, $count);
if($count == 0) {
   $class = "single";
}

echo "<li><a class=\"$class\">$newString</a></li>";

By return you mean newline? If so, you should use "\n" instead of "\r". If you would like to see the newline in a browser not just in the code you should use '<br />' instead.
