The example in this article describes the usage of the list method in PHP. Share it with everyone for your reference, the details are as follows:
<?php function small_numbers() { return array (0, 1, 2); } list ($zero, $one, $two) = small_numbers(); var_dump($zero); var_dump($one); var_dump($two); ?>
Output:
int(0) int(1) int(2)
Change it
<?php function small_numbers() { return array (0, 1); } list ($zero, $one, $two) = small_numbers(); var_dump($zero); var_dump($one); var_dump($two); ?>
Output:
Notice: Undefined offset: 2 in D:\xampp\htdocs\t\test.php on line 6 int(0) int(1) NULL
Change it again
<?php function small_numbers() { return array (0, 1 ,2 ,3); } list ($zero, $one, $two) = small_numbers(); var_dump($zero); var_dump($one); var_dump($two); ?>
Output:
int(0) int(1) int(2)
Change it again and learn by drawing inferences
<?php function small_numbers() { return array (0, 1 , array('2')); } list ($zero, $one, $two) = small_numbers(); var_dump($zero); var_dump($one); var_dump($two); ?>
Output:
int(0) int(1) array(1) { [0]=> string(1) "2" }
