PHP Array Key Value Usage example analysis, PHP array instance analysis
This example describes the PHP array key-value usage. Share to everyone for your reference. The specific analysis is as follows:
Look at an array first:
<?php$switching = Array ( ten,//key = 0 5 = 6, 3 = 7, ' a ' = = 4, one ,//key = 6 ( The maximum value of the integer key index in the entire array is 5) ' 8 ' = + 2,//Key = 8 (String health ' 8 ' is converted to 8) ' "" "+" ,//key = ' 02 ' (note not 2) 0 = 12
/* value of 10 is given 0, and the value of the 0 key is redefined, which overrides the previous default of the 0 key value */);//Empty array$empty = Array ();? >
If printed with Print_r ($switching), the result is:
Array ([0] = [5] = 6 [3] = 7 [A] = 4 [6] = [8] = 2 [Geneva] = 77)
Note that 02 of the two-digit number is in the back row.
I hope this article is helpful to everyone's PHP programming.
