Most people do not understand the knowledge points of this article "php how to get the value in the array", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "php how to get the value in the array which position" article.

Methods: 1, use "array_values (array)" to convert the specified array into an indexed array; 2, use "array_search (numeric, indexed array)" to search for values in the indexed array and return the corresponding index value (subscript); 3, because the index value is counted from 0, need to add 1 processing, syntax "index value + 1".

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

Php gets where the value is in the array

Implementation method:

Use array_values () to convert the specified array to an indexed array (mainly for associative arrays, but no change if it is already an indexed array).

$array=array ("id" = > 1, "name" = > "Li Hua", "age" = > 23, "1" = > 1, "id2" = > 52); var_dump ($array); $values=array_values ($array); var_dump ($values)

Use array_search () to search the indexed array for the specified value, and if successful, return the corresponding key name (index value or subscript).

(the key name of the indexed array is, of course, a numeric value, and each number corresponds to the position of an array element in the array)

$index=array_search (23 million values); echo $index

The key name of the indexed array is counted from 0, so add 1 to the key name.

Complete implementation code: check the position of the value 23 in the array
