Functions in PHP are of great importance, especially the one which control the flow of items. So, in this article, we will discuss List Function in PHP in the following order:
The list function in PHP is an inbuilt function which is used to assign the array values to multiple variables at a time while execution. Like array (), this is not really a function, but a language construct. list() is used to assign a list of variables in one operation.
This function will only work on numerical arrays. When the user assigns multiple values to the array, then the first element in the array is the first variable, the second one will be the second variable and so on, till the number of variables is there.
The number of variables cannot exceed the length of the numerical array if it exceeds it gives error.parameter types and return types are not written. A function with no return statements implicitly returns NULL.
The list function in PHP parameter will accept a list of variables separated by spaces in code. A parameter is just like a variable. To add more functionality to a function, we can add parameters.parameters are specified after the function name, inside the parentheses. These variables are assigned values by the user. The first variable is mandatory to the user.
|$variable1||The first variable to be assigned||Required||Mixed*|
|$variable2..n||Next variable to be assigned||Optional||Mixed*|
* Mixed: Mixed indicates that a parameter may accept multiple (but not necessary all) types.
Now let’s have a look at different examples for list functions in PHP.
<?php $array = array(1, 2, 3, 4); list($a, $b, $c) = $array; echo "x =", ($a), "n"; echo " y =", ($b), "n"; echo " z =", ($c), "n"; echo "x+y-c =", ($a*$b*$c); ?>
With this, we come to an end of this List Function in PHP article. I hope you got an understanding of what exactly happens here.
