Join David Powers for an in-depth discussion in this video Storing values in an associative array, part of Learning PHP.
- In the previous video, we looked at storing…multiple values in an indexed array.…The other type of array in PHP…is called an associative array.…Instead of a numeric index,…each array element is identified by a string.…So in effect, the array stores a set of key value pairs.…Let's create an associative array for descriptions…from The Hitchhiker's Guide to the Galaxy.…We need a variable to store our array,…I'll call it descriptions.…Then after the assignment operator,…just like an indexed array,…you can use either the array keyword…or the shorthand syntax.…
With the array keyword,…you have a comma-separated list between parentheses.…With the shorthand syntax,…you just have the comma-separated list…between a pair of square brackets.…I'm going to use the shorthand syntax.…So pair of square brackets,…and I'm going to add…an extra line in between those square brackets…so I can space my code out to make it easier to read.…We need to start off with the key for each element.…It needs to be a unique string.…We're having some descriptions…
