# PHP Challenges: Push all zeros to the end of an array

## PHP Challenges - 1: Exercise-22 with Solution

Write a PHP program to push all zeros to the end of an array.

Input : (0,2,3,4,6,7,10)

Explanation :

Sample Solution :

PHP Code :

``````<?php
function move_zero(\$arr)
{
\$count = 0;
\$n = sizeof(\$arr);

for (\$i = 0; \$i < \$n; \$i++)
{
if (\$arr[\$i] != 0)
{
\$arr[\$count++] = \$arr[\$i];
}
}

// Let all non-zero elements have been shifted towards front

while (\$count < \$n)
{
\$arr[\$count++] = 0;
}

return \$arr;
}
\$num_list1 = array(0,2,3,4,6,7,10);
\$num_list2 = array(10,0,11,12,0,14,17);
print_r(move_zero(\$num_list1));
print_r(move_zero(\$num_list2));
?>
```
```

Sample Output:

```Array
(
[0] => 2
[1] => 3
[2] => 4
[3] => 6
[4] => 7
[5] => 10
[6] => 0
)
Array
(
[0] => 10
[1] => 11
[2] => 12
[3] => 14
[4] => 17
[5] => 0
[6] => 0
)
```

Flowchart:

PHP Code Editor:

```<?php
function move_zero(\$arr)
{
\$count = 0;
\$n = sizeof(\$arr);

for (\$i = 0; \$i < \$n; \$i++)
{
if (\$arr[\$i] != 0)
{
\$arr[\$count++] = \$arr[\$i];
}
}

// Let all non-zero elements have been shifted towards front

while (\$count < \$n)
{
\$arr[\$count++] = 0;
}

return \$arr;
}
\$num_list1 = array(0,2,3,4,6,7,10);
\$num_list2 = array(10,0,11,12,0,14,17);
print_r(move_zero(\$num_list1));
print_r(move_zero(\$num_list2));
?>
```
