To know the syntax and basic usage of for and foreach loop, you can refer to the PHP for and foreach loop tutorial. We can traverse an associative array either using a for loop or foreach. Traversing an array means to iterate it starting from the first index till the last element of the array. Hence, to access an associative array, we have to use the array name along with the index of the element in square brackets, the only difference here is that the index will be a string not a numeric value like in indexed array. No matter how we initialize the array, we can access the array as follows, Syntax for the 1st way to create associative array: "Urus", "sports"=>"Huracan", "coupe"=>"Aventador") Īnd the syntax for the 2nd way to create associative array is: Just like indexed array, there are two different ways of creating an associative array in PHP, they are, I needed something like this, hence my idea of sharing it here.An associative array is similar to an indexed array, but rather than storing data sequentially with numeric index, every value can be assigned with a user-designed key of string type. * as also updating the keys would lead to reference loss of the original * the callback to the keys too (hence the need of working with a copy, * callback to the array values, not the keys, so this function simply applies * PHP's built-in function array_walk_recursive() only applies the passed * keys, and returns the resulting array copy with the updated keys and * Function which recursively applies a callback to all values and also its Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
