How to Remove elements in array using php

Question

is there an easy way to remove an element using php like square brackets [] and commas ,

here is my sample code:

while($row = $result->fetch_assoc())
{   
    //$emparray['content'][] = $row;

    $str = "
 ".$row['contentname']."
".timeElapsedSinceNow($row['publishdate'])."
".$row['desc_breif']."";

    $emparray['content'][] = $str;
    $emparray['type'] = 'html';

}

//write to json file
$fp = fopen('rsspb.json', 'w');
//have a backslashes remover
fwrite($fp, json_encode($string, JSON_UNESCAPED_SLASHES));
fclose($fp);

and output is like this:

{"content":["

The reason you get the square brackets in your JSON string, is because you've told PHP to save the data in a multi-dimentional array.

In other words, this line:

$emparray['content'][] = $str;

Is identical to this:

$emparray['content'] = array ($str);

This creates an array inside of the content index, filling it with the contents of the $str string. Making it a multi (2) dimensional array. Instead of just filling the index with the string itself.
Remove the extra set of square brackets, and you should find that your code works just the way you want it it.

Do a var_dump ($emparray) to see this for yourself.

Edit: As per your comment, you seem to also want to add more data to the content. This is where you have to make a choice: Whether you want all of the content as one string, as a whole page of HTML; Or if you want an array of strings, for different sections of a page. If it's the former, then you can just use string concatenation to add to the data in the index. For the latter, then you need to use an array and just deal with it on the client side.
