multidimensional array search

In PHP to implement the array search method There are many, I know the simplest is in_array and iterate after the array and then a comparison, there are more and better ways, let me introduce. One-dimensional array search is simple In_array () If

I think so: Iterate through multidimensional arrays and create a one-dimensional array by indexing all the keys; Each time through the key name to check the parent array and data OK, the code is as follows Indexkey Creating an indexed array function:

For Web programming, the most important thing is to access and read and write data. There may be many ways to store them, such as strings, arrays, files, and so on. arrays, which can be said to be a more important way of using PHP data. PHP's Array

1. The concept of arrays An array is a named range that is used to store a series of variable values. Each array element has an associated index (also a keyword) that can be used to access elements. PHP allows you to use numbers or strings evenly

PHP has a lot of functions about arrays to facilitate array manipulation. Defined: Each entity of an array contains two items: key and value, which can be retrieved by a query key. These keys can be numeric (numerical) or associated (associative)

Learn PHP's array summary "experience", PHP array Summary PHP has a lot of functions for arrays, which makes it easy to manipulate arrays. Defined: The array contains two items per entity: Key and value, which can be obtained by querying the key.

That's what I think: Iterate over the multidimensional array, all the keys to build an index to generate a one-dimensional array; Each time through the key name to check the parent array of this key and data OK, the code is as follows Indexkey to

Ange ($low, $high), Range ($low, $high, $step);//Create an array of sequential values such as: Range (1,4) as (1,2,3,4) and range (' A ', ' Z ') Each ($array) returns the current element of the array sequentially, and sets the next element to the
