Just more standard.Ĭhanged the return values for "no array" and "no variable" to $a = "I am Groot!" $a = array() echo $a //I am Groot! $a = array("cat", "dog") $a = array() echo $a //$aĪfter "$a = array() " the variable $a is an array with zero elements: + Scripting | Arrays: You can use array() without any values to completely reset an The syntax is a bitĭifferent from the old token-list loop syntax:įoreach($variable, ListOfTokens,, , ) + Scripting | Arrays: Now the foreach loop supports arrays. $a ="cat" echo array_count($a) //6 (they first 5 elements have been silently created) $a = array("Banana", "Cherry", "Apple") $b = "b" echo array_count($c) //no variable $a = array("Banana", "Cherry", "Apple") $b = "b" echo array_count($b) //no array If the variable does not exist, the function returns "no variable". If the variable is no array, the function returns "no array". Variable: Bare variable name of the array. $name = array(cat=>pussy,dog=>rex) echo $name //rexĪction: Retrieves the number of elements of an array. = array("key1" => "value1", "key2" => "value2")Īgain, you can get away with stripping the quotes and the spaces: $name = array("cat" => "pussy", "dog" => "rex") echo $name //pussy So far the indexed arrays, but you can also populate associative arrays using array(): The values are added to the array in the order they are listed, starting with element. If you like you can append to the variable, it makes no difference: The values can also be in single quotes but those will not be removed. (fine if you are not using any commas or flanking spaces within the values): The values can be in double quotes (which will be removed), or also without quotes You can only pass literal strings as values, not variables. $a = array("cat", "dog") echo $a $a = array("dog") echo $a //cat, dog Non-existing arraysĪre created, dimensioned and populated, existing arrays are redimensioned and + Scripting: Added special function array() to populate arrays. + Scripting | Arrays: Globals arrays were poorly done. This will also help in fixing any fresh bugs. It's a good idea to backup your complete XYplorer settings (menu File | Settings Special | Backup Application Data Folder.) before running a new BETA version. Note that BETA versions are work in progress and might contain fresh bugs. To download it, choose a package: (1) Installer Package, (2) No-Install Package. To update to this BETA version from XYplorer, hold down the CTRL key while you click Help | Online Support | Check for Updates. > There have been some RADICAL CHANGES in scripting related code. No performance tests have been done yet, but I wouldn't expect miracles. The perm command is not supported by arrays but is simply ignored: Arrays cannot $a = "Uhm" //not global, won't work below Global command must be used in the source and the target location (it's weird but The global command is supported by arrays. $a ="cat" echo $a //$a ($a does not exist as variable) $a ="cat" echo $a //"" ($a is implicitly created and set to "") If you assign a non-first element in a new or smaller indexed array, all previousĮlements starting with are automatically created (with value ""): $a ="cat" $a = "dog" echo $a echo $a //"cat", "dog"īut they share the same perm/global properties, so think of this $a as $a,Īs just one more place to store a value in. Array variables and normal variables with the same base name can be used side by Allowed range of elements per array: 0 to 32767 (= 32768 max for assoc arrays). Also a missing key makes the variable invalid: $a ="cat" echo "It is a $a!" //It is a $a! If the index or key is invalid the variable is seen just as a bit of text: $a ="cat" echo "It is a $a!" //It is a cat! Array elements also work within quotes: + Scripting | Arrays: No new features, but completely rewritten with scalabililty andįuture in mind.
