![]() The foreach statement goes through the array elements or object properties one by one and the current value is copied to a variable defined in the construct. The foreach statement simplifies traversing over collections of data. (2) if the key name is present in the $rec_items array. php -v php -v PHP 8.1.2 (cli) (built: 07:28:23) (NTS). (1) dynamically loop through key names in the format 'title*' I just share the above to try to highlight what i'm trying to achieve. The ‘foreach’ loop implicitly does this too. In addition to this, no condition needs to be set that would be needed to exit out of the loop. The ‘foreach’ loop works with arrays only, with the advantage that a loop counter wouldn’t need to be initialized. I've tried pushing numeric numbers from a counter variable into key names to be searched for (like below): foreach ($rec_items as $key => $value) as a string with no luck. The ‘foreach’ loop in PHP helps in accessing key value pairs within an array. In this example, we will take an associative array of key-value pairs, and iterate over each of the key-value pairs in the array, and execute a block of code (or statements) for each key-value pair. ![]() 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). This is because when the second loop executes, entry is still a reference. I have a number of values in an array with key values that follow the same naming format.Įxample: $rec_items = implode($meta) This is an example why pass-by-reference in foreach loops is BAD. ![]() ![]() What are some of the best ways to iterate through combinations of $key names - doing something different for each- in a php foreach loop? I feel like i'm missing something quite simple. Inside of a for loop block you can access some special variables. ![]()
