In this guide, we will talk about the syntax and working of the PHP “pos()” function.
What is the “pos()” Function in PHP?
The “pos()” function is used to get the value of the element that is currently selected in an array in PHP. It mostly applies to arrays that rely on the concept of “positional array” to implement them. A positional array gives its members numerical keys that begin at “0”, making it simple to obtain certain values with the “pos()“ method.
Syntax
The general syntax of the “pos()” function is provided given:
Parameter: The pos() function takes one parameter as an array that returns the present array element. If the array is empty or the internal pointer is longer than the array size, then it will return false.
Let’s take a look at the given example of the pos() function in PHP to understand its working.
Example: Access Elements of an Array Using “pos()” Function in PHP
To access the elements of an array with respect to the current position of the array element using the “pos()” function, first, initialize an array “$days” with three string type values as “Monday”, “Tuesday”, and “Wednesday”. Then, invoke the “pos()” function and pass it the “$days” variable as a parameter. After that, save it to the “$present_Day” variable. Lastly, display the resultant array element by using the “echo”:
The value of the “$present_Day” has been displayed on the below-given output:
Note that the pos() function is the alias of the PHP current() function. That’s all! You have learned about the “pos()” function in PHP.
Conclusion
In PHP, the “pos()” function plays an important role when working with “positional arrays”. It makes array manipulation positions simpler by supplying the current value and granting simple access to array elements. This guide stated an example of the “pos()” function to access the present element of an array in PHP.
