# Display which row and which column has the biggest number of 1's

Hi,

I am new to PHP and I have this homework due Sunday, I got it on Friday btw, this Friday I have complete the first part of it , but I can not complete the second part of it. This is the exercise:

Largest Row and Column

Write a 4x4 array and fill it with random 1â€™s or 0â€™s

0 0 1 1

0 1 0 0

1 0 1 1

1 0 0 1

Display which row and which column has the biggest number of 1â€™s

this is my code:

<?php \$num = array("0", "1"); \$rows = rand(4, 4); //using rand() function to generate 4 different numbers, min & max=4 \$cols = rand(4, 4); echo ""; for(\$i = 1; \$i <= \$rows; \$i++) { echo ""; for(\$j = 1; \$j <= \$cols; \$j++) { \$td_text = \$num[rand(0,(count(\$num)-1))]; //number spacing echo ''; } echo ""; } I have an idea : to store random numbers of the array in new array than to count 1's and then to display which row/col have the biggest number of 1's and then echo the result. I googled and I could not find a function or method to store random numbers into an array. Could you please help me I am confused .
 '.\$td_text.'

You didnt format your codeâ€¦ so its truncated or somethingâ€¦

There are many ways to get your total â€˜countsâ€™ hereâ€¦ are there are restrictions? or ways you were told to approach this?

Do you need to use any specific functions or approaches?

You could implode and do a string count in a loop?

That task sounds pretty random, like thereâ€™s a bigger problem, whatâ€™s the actual use case? Anyway, if you combine these numbers into one string per row as mentioned, you could use the `substr_count` function.

OP was already given complete working code on another forum.

Thank you for your replies . I am sorry that I have written bad the code.I solve it
