In this tutorial I’m going to learn what are the difference between double == equal operator and triple equal operator === this tutorial will help you what are the exactly difference between them.
The == operator and === operator in Laravel are both used to compare two values. However, there is a subtle difference between the two operators.
The == operator checks if the two values are equal, regardless of their data types. For example, the following code will return true:
PHP
$a = 1;
$b = '1';
echo $a == $b; // true
Use code with caution. Learn morecontent_copy
This is because the == operator will automatically convert the string '1'
to the integer 1
before comparing the two values.
The === operator, on the other hand, checks if the two values are equal and have the same data type. For example, the following code will return false:
PHP
$a = 1;
$b = '1';
echo $a === $b; // false
Use code with caution. Learn morecontent_copy
This is because the === operator will not automatically convert the string '1'
to the integer 1
. Instead, it will compare the two values as strings, and the strings are not equal.
In general, you should use the === operator when you need to be sure that the two values are equal and have the same data type. The == operator can be used when you are not concerned about the data types of the values.
Here is a table summarizing the differences between the == and === operators:
Operator | Description |
---|---|
== | Checks if the two values are equal, regardless of their data types. |
=== | Checks if the two values are equal and have the same data type. |
