(2) if the key name is present in the $rec_items array. (1) dynamically loop through key names in the format 'title*' I just share the above to try to highlight what i'm trying to achieve. I've tried pushing numeric numbers from a counter variable into key names to be searched for (like below): foreach ($rec_items as $key => $value) as a string with no luck. I would like to be able to dynamically cycle through key names in $rec_items, and 'do something' when a key is found that matches title*. I'm looping through $rec_items with a foreach loop. The $rec_items array also contains other values that do not follow this naming convention (or data type). There are two types of array, and the type of key that is used to access an array element dictates the array type. I have a number of values in an array with key values that follow the same naming format.Įxample: $rec_items = implode($meta) What are some of the best ways to iterate through combinations of $key names - doing something different for each- in a php foreach loop? The syntax of the foreach loop is shown below. During each iteration, we can access respective key and value of the associative. As we know, that array contains a pair of keys and values the foreach loop is used to loop through the key/value pair of an array. To iterate over key-value pairs of array in PHP, we can use foreach statement. On each iteration, the value of the current element is assigned to value. The foreach loop is a special loop that works only on the array. There are two syntaxes: foreach (iterableexpression as value) statement foreach (iterableexpression as key > value) statement The first form traverses the iterable given by iterableexpression. We can utilize the foreach loop to access the array elements. If the internal pointer points beyond the end of the elements list or the array is empty, key () returns null. I feel like i'm missing something quite simple. We can see the array is numerically indexed. The key () function simply returns the key of the array element that's currently being pointed to by the internal pointer.
