How to add string value with integer and float value in PHP ,2024

In PHP, you can add a string value with a float value by first converting the string to a float (or vice versa) and then performing the addition. Here’s how you can do it:

$str1 = "3.14";
$str2 = "4.14";

$sum = (float)$str1 + (float)$str2;

echo $sum; // Output: 7.28

Keep in mind that when adding a string to a float, PHP will try to convert the string to a numeric value before performing the addition. If the conversion is not possible, the string will be treated as 0. It’s important to ensure that the string contains a valid numeric representation if you want to perform arithmetic operations with it.
