# How to count the number of digits in a integer in PHP

In this tutorial we are going to learn, how to count the number of digits in a given integer in PHP with the help of examples.

Consider, we have following integer in our php code.

``\$pincode = 600583;``

To count the number of digits in a given integer, first we need to convert the number to a string using the `strval()` method then pass it to the strlen() method to get total number of digits in integer.

The `strlen()` function takes the string as an argument and returns the total number of characters in it.

Here is an example:

``````\$pincode = 600583;
\$count = strlen(strval(\$pincode));

echo \$count;``````

Output:

``6``

In the example above, we first called the `strval()` by passing a `\$pincode` , so it converts the number to a string then we used the `strlen()` method to get the total number of digits.

Similarly, we can use the logarthmic solution in php to get the total number of digits from a number.

Here is an example:

``````\$pincode = 600583;
\$count = ceil(log10(\$pincode));

echo \$count;``````
