I want to add some extra values by using foreach loop.
foreach($a as $b) {
echo $b; // this will print 1 to 6
}
Now I want to edit last item with custom text and print like this
1
2
3
4
5
6 this is last.
how can i do this? Please help I am new in PHP.
You can use end of array
<?php
$a = array(1,2,3,4,5,6);
foreach($a as $b) {
echo $b; // this will print 1 to 6
if($b == end($a))
echo "this is last.";
echo "<br>";
}
EDIT as @ alexandr comment if you have same value you can do it with key
<?php
$a = array(6,1,2,3,4,5,6);
end($a); // move the internal pointer to the end of the array
$last_key = key($a);
foreach($a as $key=>$b) {
echo $b; // this will print 1 to 6
if($key == $last_key)
echo "this is last.";
echo "<br>";
}
[6, 1, 2, 3, 4, 5,6]
unknown number of array?<?php
$a = array(1,2,3,4,5,6);
$last = count($a) - 1;
foreach($a as $k => $b) {
echo $b; // this will print 1 to 6
if($k == $last)
echo "this is last.";
echo "<br>";
}
You can declare inc variable, and use with array count
<?php
//$b is your array
$i=1;
foreach($a as $b) {
if(count($a)==$i){
echo $b; // this is last
}
$i++;
}
?>
Use count, the thats way you get the size and you can use in a condicional like if
$size=count($a);
foreach($a as $b) {
if ($b==$size)
{
echo $b. "This is the last"; // this will print 6 and text
}
else
{
echo $b; // this will print 1 to 5
}
}
You can use array_slice which is a good way to slice up an array.
You can set it to get the last item(s) with negative numbers.
$arr = array(1,2,3,4,5,6);
$last = array_slice($arr, -1, 1)[0]; // 6
$other = array_slice($arr, 0, -1); // [1,2,3,4,5]
foreach($other as $item){
echo $item;
}
echo $last . " this is the last";
if (b == 6)for example.
