This article will explain in detail how php queries array values according to the location of the array. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Php query the array value according to the array location: 1, use the "$array variable name [subscript value]" statement; 2, use the "array_slice ($arr, subscript value, 1)" statement; 3, use the "array_splice ($arr, subscript value, 1)" statement.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

The method of querying array values according to array position by php

Method 1: use the form of $array variable name [subscript value]

Method 2: using the array_slice () function

The array_slice () function can intercept a value of a specified length based on the given array position and return the truncated subarray.

If you just want to get an element, you can set the third parameter of the array_slice () function to 1.

Example: get the element value with subscript 1

Method 3: using the array_splice () function

Similar to the array_slice () function, if you just want to get an element, you can set the third parameter of the array_splice () function to 1.
