Ternary Operator in Concatenation for Dynamic Display
Attempting to use an if statement within concatenation, as exemplified below, may prove futile:
$display = '<a href="' . $row['info'] . '" onMouseOver="' . if($row['type']=="battle"){ . 'showB' . } else { . 'showA'() . "><div class='" . $row['type'] . "_alert" . '" style="float:left; margin-left:-22px;" id="' . $given_id . '"></div></a>';
Solution: Utilizing the Ternary Operator
The if statement serves as a standalone statement, rendering it unsuitable for interpolation within strings. Instead, the ternary operator is more appropriate for this purpose. It takes the form:
(conditional expression)?(output if true):(output if false);
Implementation within Concatenation
To incorporate the ternary operator within concatenation effectively, consider the following example:
$i = 1; $result = 'The given number is'.($i > 1 ? 'greater than one': 'less than one').'. So this is how we can use ternary inside concatenation of strings';
Nested Ternary Operators
For even more complex conditional evaluations, nested ternary operators can be employed, as illustrated below:
$i = 0 ; $j = 1 ; $k = 2 ; $result = 'Greater One is'. $i > $j ? ( $i > $k ? 'i' : 'k' ) : ( $j > $k ? 'j' :'k' ).'.';
