Hey,
I have a $data_recs array like this:
12
445
45655
4
343
etc
when the user gives me a number, i have to check if its in the array and
delete that entry...how do i do that?
I have looked at the manual but have gotten confused with array
pop,splice,array_key_exists etc
Thanks,
Ryan

 

The code follows :
if (in_array($number, $data_recs)) {
   $key = array_search($number, $data_recs); // Get the key
  unset($data_recs[$key]); // Unset the variable
}

foreach ($array as $key=$value)
{
if(strpos($value, $userValue)
{
unset($array['$key']);
}
}

sorry the if bit is not strpos
if ($value == $userValue)
{
// the unset part here
}

http://php.net/array_search
http://php.net/unset

It can be confusing at first, with all the different functions that all
seem to do not quite what you want. :-)

 Exactly...theres a s**tload of array functions there...and php being so
robust I figured there would be one simple function instead of combining
two
I have unsed unset in the past...but not array_search

Thanks,
