This article will explain in detail how to use the function to solve the deletion of PHP array, the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

PHP is one of the most commonly used programming techniques, so I studied the deletion of the PHP array, and I hope it will be useful to share it with you. PHP is a server-side scripting language that is easy to learn and use. With little programming knowledge, you can use PHP to build a truly interactive WEB site.

PHPLIB is the most commonly used set of base libraries that can provide general service needs. -scalability, as mentioned earlier, PHP has entered a period of rapid development. It may be difficult for a non-programmer to add functionality to a PHP extension, but it is not difficult for a PHP programmer. Object-oriented programming PHP provides classes and objects. The programming based on web needs the ability of object-oriented programming. PHP supports constructors, extraction classes, and so on. -scalability traditionally the interaction of web pages is achieved through CGI. The scalability of the CGI program is not ideal because it opens a separate process for each running CGI program, so let's take a look at the PHP array deletion code in detail.

PHP array delete code:

/ * remove blank elements from the array (including those with only white space characters) * * @ param array $arr * @ param boolean $trim * / copy the code as follows: function array_remove_empty (& $arr, $trim = true) {foreach ($arr as $key = > $value) {if (is_array ($value)) {array_remove_empty ($arr [$key]);} else {$value = trim ($value) If ($value = =') {unset ($arr [$key]);} elseif ($trim) {$arr [$key] = $value;} / * converts a two-dimensional array to hashmap * * if the $valueField parameter is omitted, each item is an array containing all the data for that item. * * @ param array $arr * @ param string $keyField * @ param string $valueField * * @ return array * / copy the code as follows: function array_to_hashmap (& $arr, $keyField, $valueField = null) {$ret = array (); if ($valueField) {foreach ($arr as $row) {$ret [$row [$keyField]] = $row [$valueField];} else {foreach ($arr as $row) {$ret [$row [$keyField] = $row }} return $ret;} on how to use the function to solve PHP array deletion is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
