The is_array function is used to determine whether a variable is a valid array or not. The count function is used to get the number of items that have been stored in an array Multidimensional arrays contain other arrays inside them. PHP Associative array use descriptive names for array keys Numeric arrays use numbers for the array keys Output: Array ( => Female => Female => Male ) Why use arrays?Īrrays easily help group related information such as server login details togetherĪrrays are special variables with the capacity to store multi values.Īrrays are flexibility and can be easily stretched to accommodate more values The following example illustrates its usage. This function is used to sort the array using the values. 'Female', 'John' => 'Male', 'Mirriam' => 'Female') Īrray ( => Male => Female => Female ) asort This function is used to sort the array using the key. Output: Array ( => Female => Female => Male ) ksort The output of this function is a numeric array 'Female', 'John' => 'Male', 'Mirriam' => 'Female') It removes the existing access keys and add new numeric keys. If the values are numeric, it sorts them in ascending order. If the values are alphanumeric, it sorts them in alphabetical order. This function is used to sort arrays by the values. Let’s now look at an example that implements the is_array functions. The is_array function is used to determine if a variable is an array or not. The count function is used to count the number of elements that an php array contains. Note: the movies numeric array has been nested inside the categories associative array PHP Arrays: OperatorsĬompares two arrays if they are equal and returns true if yes. Output: Array ( => Array ( => Pink Panther => John English => See no evil hear no evil ) => Array ( => Die Hard => Expendables ) => Array ( => The Lord of the rings ) => Array ( => Romeo and Juliet ) )Īnother way to define the same array is as follows array( 'epic' => array('The Lord of the rings'),

'action' => array('Die Hard', 'Expendables'), array('Pink Panther', 'John English', 'See no evil hear no evil'), The above information can be represented as a multidimensional array. The table below shows a list of movies by category. Let’s now look at a practical example that implements a php multidimensional array.
