The method of adding elements at the end of two-dimensional array by php
1. Use the array_push () function
The array_push () function inserts one or more elements (key values) at the end of the array.
The added element can also be an array type:
Array_push ($arr,array ("Li Hua", 22, "male")
2. Use the array_splice () function
The array_splice () function is a powerful function that can be used to delete, replace, or insert array elements (just set the parameter $length to 0).
When $length=0, the parameter $start specifies where to start the insertion (subscript), and the parameter $value specifies the insertion value (if it is multiple values, it needs to be set to an array).
To insert an element at the end of an array, simply set the value of $start to "array length value", that is, count ($arr).
If you want to add more than one element, set the four parameters to the array type
Array_splice ($arr,count ($arr), 0Jane array ("1", 25, "3"))
