I believe that the students running on the path of the script, can feel that the script needs to apply variables in a very wide area, simply to see the variable is simply: var=value; if we go deep into it, we can also find that the knowledge of

Functions commonly used in PHP arrays:1.//array_values-returns all values in the array　$array = Array ("name" = "Zhangsan", "age" = "ten", "sex" = "man");　　$tem = Array_values ($array);　　echo "pre>";　　Print_r ($tem); echo "pre>";The output results

Some php array learning notes. There are three types of php arrays: a numeric array with a numeric ID key, and an ID key in an array associated with a value multi-dimensional array containing one or more arrays, there are three types of php arrays:

There are three types of php Arrays: a numeric array with a numeric ID key, and an ID key in an array associated with a value multi-dimensional array containing one or more arrays, now let's look at my notes. The Code is as follows:

. The code is as follows: Header (' content-type:text/html; Charset=utf-8 ');Echo ' ';function Var_array ($array){Echo ' ';Var_dump ($array);Echo ' ';}function Printr ($array){Echo ' ';Print_r ($array);Echo ' ';}function Getarr ($sNum, $eNum =1

The technology is not refined. If you have any mistakes, please point out that I will correct them.Copy codeThe Code is as follows:Header ('content-Type: text/html; charset = UTF-8 ');Echo ' ';Function var_array ($ array){Echo ' ';Var_dump ($ array )

Example to detect if the PHP array is an indexed array. function Is_assoc ($arr) { Return Array_keys ($arr)!== range (0, COUNT ($arr)-1); Array_values ($arr)!== $arr } function Is_assoc2 ($array) {

The technique is not fine, must have the mistake, also please point out, I will correct. Copy the Code code as follows: Header (' content-type:text/html; Charset=utf-8 ');Echo ' ';function Var_array ($array){Echo 'Echo '';}function Printr

PHP accurately determines if an array is indexed function Is_assoc ($arr) { return Array_keys ($arr)!== range (0, COUNT ($arr)-1);//Array_values ($arr)!== $arr} function Is_assoc2 ($array) { return (BOOL) count (Array_filter (Array_keys

function set(array &$array, $path, $value){ print_r($array); echo(''); $segments = explode('.', $path); while(count($segments) > 1) { $segment = array_shift($segments); if(!isset($array[$segment]) ||

echo $keyword = "Shanghai | Beijing, Chengdu, Shenzhen"; echo ""; $old 1 = Array ("/(\s*) (\s) (\s*)/", "/(\s*) (\|) (\s*)/","/(\s*) (!) (\s*)/"); $new 1 = Array ('" ' ", '" | "', '" "! '); echo $keyword 3= "\" ". Preg_replace ($old 1, $new 1,
