php foreach skip iteration

how to skip elements in foreach loop

I want to skip some records in a foreach loop.

For example, there are 68 records in the loop. How can I skip 20 records and start from record #21?

Five solutions come to mind:

Double addressing via array_keys

The problem with for loops is that the keys may be strings or not continues numbers therefore you must use «double addressing» (or «table lookup», call it whatever you want) and access the array via an array of it’s keys.

Skipping records with foreach

I don’t believe that this is a good way to do this (except the case that you have LARGE arrays and slicing it or generating array of keys would use large amount of memory, which 68 is definitively not), but maybe it’ll work: 🙂

Using array slice to get sub part or array

Just get piece of array and use it in normal foreach loop.

Using next()

_{btw: I like hakre’s answer most.}

Using ArrayIterator

Probably studying documentation is the best comment for this one.

if want to skipped some index then make an array with skipped index and check by in_array function inside the foreach loop if match then it will be skip.

Example:

You have not told what «records» actually is, so as I don’t know, I assume there is a RecordIterator available (if not, it is likely that there is some other fitting iterator available):

I’m not sure why you would be using a foreach for this goal, and without your code it’s hard to say whether this is the best approach. But, assuming there is a good reason to use it, here’s the smallest version I can think of off the top of my head:

The continue causes the foreach to skip back to the beginning and move on to the next element in the array. It’s extremely useful for disregarding parts of an array which you don’t want to be processed in a foreach loop.

This is better than a foreach loop because it only loops over the elements you want. Ask if you have any questions

Element would be the current value of index. Index increases with each turn through the loop. IE 0,1,2,3,4,5; array[index];
