The unset() function is also used to remove elements from array by key. But the problem is once we use the foreach loop it will not unset all the variables given and there will be one variable remaining. Solution To delete one element, use unset ( ): unset (array 3) unset (array 'foo') To delete multiple noncontiguous elements, also use unset ( ) : unset (array 3, array 5) unset (array 'foo', array 'bar') To delete multiple contiguous elements, use arraysplice ( ) : arraysplice (array, offset, length) 4.6.3. To unset multiple values we will just need to use for loop and foreach loop. } How do you unset multiple values in PHP? If it’s only one element, it can be a string and does not have to be an array. Specifies an array with the elements that will be inserted into the original array. If this value is not set, the function will remove all elements, starting from the position set by the start parameter. If this value is set to a negative number, the function will stop that far from the last element. Specifies how many elements will be removed, and also the length of the returned array. 2 means start at the second last element of the array search. ![]() If this value is set to a negative number, the function will start that far from the last element. Specifies where the function will start removing elements. Parameter values: Parameter Description array Required.

Yet the foreach loop still iterates through those and gives me back a bunch of empty arrays. So on the first iteration it uses $array obviously but the $searchresults might return 4,5,6,7. $searchresult = search function returns various other keys from array I do NOT want to reindex if at all possible, although if I have to I can. It's a search function so I'm removing the element I just searched for, so when the loop runs again its minus that element. I'm iterating through an array with foreach. It's the first part of that that is messing with me. – Kevin Peno Dec 22 '09 at 21:31" from How do you remove an array element in a foreach loop? It will iterate on the offset, but the value will be null. Here's a way to find all the keys from a multidimensional array while keeping the array structure. Test unsetting a value that is next in iteration. There's a lot of multidimensional arraykeys function out there, but each of them only merges all the keys in one flat array. So I just learned that "A php foreach will execute on the entire array regardless. Ran into a little snag and wondering if there is a "best practices" way around it. ![]()
