How to Handle PHP Variable Insertion in Strings to Maintain Spacing and Variables?

Displaying Strings with PHP Variables

When attempting to output a string containing a PHP variable, such as "$width," it can be challenging to retain the necessary spacing and variables. Exploring alternative syntax options can resolve this issue.

Solution 1:

<code class="php">$bla = '<div class="vote_pct" style="width: ' . $width . 'px;">';</code>

In this approach, the variable is enclosed in single quotes and the string is concatenated using the '.' operator. The space between the variable and the unit is added explicitly.

Solution 2:

<code class="php">$bla = "<div class=\"vote_pct\" style=\"width: ${width}px;\">";</code>

Here, curly braces are used to embed the variable within the string. This eliminates the need for concatenation and automatically includes the space.
