Removing array element - Please help.

[john551]

I have stored some data in a single string seperated by comma.
Example:

$data="john,hari,gupta";
Now I want to remove hari from the $data and form the string as
$data="john,gupta";

I have exploded the data using explode function.
explode(',',$data);
But I dont no how to remove the element and form the string as shown in the example above. Please help

if your goal is to remove ",hari" from the string, you can just issue a str_replace command to remove it:

$data = str_replace(",hari","",$data);

this was an example in above post.
The data string is dyanmically fetched from mysql.

The data could be anyhing like
$data="john,peter,dsa,weer,syz";

Now how have a form where I post say john, it should delete 'john' and form the string as
$data="peter,dsa,weer,syz";

If I use str_replace(',john', '', $data) it would'nt work. So any other way

If your are using explode then this would work

$data="john,hari,gupta";
$array=explode(",",$data);
foreach($array as $key=>$value)
{
if ($value=='john')
{
unset($array[$key]);
}
}

sort($array); // If you want to re order it

Slight modification:

<?php
$data= "john,hari,gupta";
$item = "hari";
$tmp = explode(",", $data);
unset($tmp[array_search($item, $tmp)]);
$data = implode(",", $tmp);
?>
