How to skip iteration in foreach inside foreach - php

Question

I have an array of values, and i want to insert the values to another array but with an if condition, if the "if" is true I want to skip the iteration.
Code:
$array=array(array(1=>11,2=>22,3=>23,4=>44,5=>55));
$insert=array();
foreach($array as $k1=>$v1)
{
foreach($v1 as $k2=>$v2)
{
if($v2==23)
{
break;
}
}
$insert[]=$v1;
}
final result should look like that
Array
(
[0] => Array
(
[1] => 11
[2] => 22
[3] => 44
[4] => 55
)
)
I tried using: break,return,continue...
Thanks

There are a few ways to do this. You can loop over the outer array and use array_filter on the inner array to remove where the value is 23 like this (IMO preferred; this also uses an array of $dontWant numbers so it is easier to add or change numbers later):
<?php
$array = array(array(1=>11,2=>22,3=>23,4=>44,5=>55));
$insert = array();
//array of numbers you don't want
$dontWant = array(23);
//loop over outer array
foreach($array as $subArray){
//add to $insert a filtered array
//subArray is filtered to remove where value is in $dontWant
$insert[] = array_filter($subArray, function($val) uses ($dontWant) {
//returns true if the value is not in the array of numbers we dont want
return !in_array($val, $dontWant);
});
}
//display final array
echo '<pre>'.print_r($insert,1).'</pre>';
Or you can reference the first key to add to a sub array in $insert like (which is a little more like what your code is trying to do and show that you are not too far off):
<?php
$array = array(array(1=>11,2=>22,3=>23,4=>44,5=>55));
$insert = array();
//loop over outer array
foreach($array as $k1=>$v1){
//add an empty array to $insert
$insert[$k1] = array();
//loop over inner array
foreach($v1 as $k2=>$v2){
//if the inner array value is not 23
if($v2 != 23){
//add to inner array in insert
$insert[$k1][] = $v2;
}
}
}
//display the result
echo '<pre>'.print_r($insert,1).'</pre>';
Both of these methods would produce the same result. IMO using array_filter is the preferred method, but the second method might be a little easier to understand for someone new to programming.

Answer 2

Why don't you just try it like this?
foreach($v1 as $k2=>$v2)
{
if($v2!=23)
{
$insert[]=$v2;
}
}
EDIT:
Explanation: You check with the if($v2!=23) if the value of the variable $v2 is not equal to (that is the != sign) any given number that stands after the inequality operator, and if so, it will insert that value to the array $insert.
I hope it is clear now.
Sorry, I've written $v1 instead of $v2, the code should work now.

To add variants :)
$array=array(array(1=>11,2=>22,3=>23,4=>44,5=>55));
$insert=array();
foreach($array as $a)
{
while (($i = array_search(23, $a)) !== false)
{ unset($a[$i]); sort($a); }
$insert[] = $a;
}
print_r($a);
result:
Array ( [0] => Array ( [0] => 11 [1] => 22 [2] => 44 [3] => 55 ) )
