Collection: 1. Understanding and benefits of collection: 1.

Detailed explanation of PHP array processing using three functions such as foreach, list, and each
This article introduces how to use the three functions foreach, list, and each for traversing arrays in PHP: Method 1: foreach<?php$sports = array(football => good,swimming => very well ,running => not good);foreach ($sports as $key => $value) {echo $key.”: “.$value.”“;?> Output result:football: goodswimming: very wellrunning: not good Method 2: each<?php$sports = array(football => good,swimming => very well ,running => not good);while ($elem = each($sports)) {echo $elem[key].”: “.$elem[value].”“; ?> Method 3: list & each<?php$sports = array(football => good,swimming => very well,running => not good);while (list($key, $value) = each($sports)) {echo $key.”: “.$value.”“;?>
Summary of PHP array traversal statements (foreach, for, list, each)
There are several methods for traversing and reading arrays in PHP. foreach, for, list, each, and while are all possible, but the one is more suitable for traversing arrays. When using foreach to access, is the order of traversal fixed? In what order should it be traversed? For example: the code is as follows: <?php $colors= array('red','blue' ,'green','yellow'); foreach ($colors as $color){ //add your codes } ?> Example 2, the code is as follows: $capitals= array( “Ohio”=> “Columbus”,“Towa”=> “Des Moines”,“Arizona”=> “Phoenix”); foreach($capitals as $key=> $ val){ //add your codes } while() while() is usually used in conjunction with list() and each(). The example code is as follows: <?php $colors = array('red','blue' ,'green','yellow'); while(list($key,$val) = each($colors)) { echo “Other list of $val.“ ; } ?> /* Display results: Other list of red. Other list of blue. Other list of green. Other list of yellow. */ 3. for(),The example code is as follows: <?php $arr = array (“0” => “zero”,“1” => “one”,“2” => “two”); for ($i = 0;$i < count($arr); $i++) { $str = $arr$people)) { echo “$key => $val“ ; } ?> /* Output: 0 => Peter 1 => Joe 2 => Glenn 3 => Cleveland */ Recursive traversal of multi-dimensional…
PHP Development (21)-Use foreach, list, while, each to traverse arrays-PhpStorm
foreach: There are many methods for traversing arrays. In other languages, arrays with consecutive subscripts are generally traversed using for, but based on The particularity of PHP arrays, we generally use foreach, and sometimes each. First, let’s take a look at arrays in most languages: $arr = array(“a”, “b”, ” c”, “d”, “e”, “f”, “g”); Then let’s take a look, PHP Array forms that can exist in: $arr2 = array(“a”, “b”, 100=>”c”, “d”, “xxx”=>”e”, “f”, “g”); Yes, arr2 cannot be traversed using for~~So, there is a powerful foreach method~~ foreach has 2 expressions: 1. foreach (array as custom variable) 2. foreach (array as subscript variable => value variable) list: list() Assigns a value to a set of variables in one operation. Note that list can only convert consecutively indexed arrays into variables. I personally feel that list does not have any advantages, except when used with the explode function. explode() explodes a string into an array. In the following code, an example is demonstrated: list($name, $web) = explode(“_”,$ str); each: each() returns The key name and key value of the current element and moves the internal pointer forward. current() – Returns the value of the current element in the array.…
Complete list of PHP array traversal methods (foreach, list, each)_PHP tutorial
Arrays are divided into two categories in PHP: numerically indexed arrays and associative arrays. The numeric index array is the same as the array in C language, the subscripts are 0, 1, 2… The subscript of the associative array may be of any type, similar to hash, map and other structures in other languages. The following introduces three methods of traversing associative arrays in PHP: Method 1: foreach The code is as follows: <?php $sports = array( ‘football’ => ‘good’, ‘swimming’ => ‘very well’, ‘running’ => ‘not good ‘); foreach ($sports as $key => $value) { echo $key.”: “.$value.”“; ?> Output result: football: good swimming: very well running: not good Method 2: each The code is as follows: <?php $sports = array( ‘football’ => ‘good’, ‘swimming’ => ‘very well ‘, ‘running’ => ‘not good’); while ($elem = each($sports)) { echo $elem[‘key’].”: “.$elem[ ‘value’].”“; ?> Method 3: list & each The code is as follows: <?php $sports = array( ‘football’ => ‘good’, ‘swimming’ => ‘very well’, ‘running’ => ‘not good’); while (list($key, $value) = each($sports)) { echo $key.”: “.$value.”“; ?> http://www.bkjia.com/PHPjc/322119.htmlwww.bkjia.comtruehttp://www.bkjia.com/PHPjc/322119.htmlTechArticleArrays in PHP are divided into two categories: numerical index arrays and associative arrays.

Other list of blue. Other list of green. Other list of yellow. 3. for() #example3: The code is as follows <?php $arr = array (“0” => “zero”,”1″ => “one”,”2″ => “two”); for ($i = 0;$i <count($arr); $i++) { $str = $arr[$i]; echo “the number is $str.“; } ?> Display results: the number is zero. the number is one. the number is two. ========== The following is an introduction to the function ========== key() mixed key(array input_array) The key() function returns the key element in input_array at the current pointer position. #example4 The code is as follows <?php $capitals = array(“Ohio” => “Columbus”,”Towa” => “Des Moines”,”Arizona” => “Phoenix”); echo “…
