[PHP] array_search() problem

[David Orn Johannsson]

Hi I'm runing a PHP Version 4.0.4pl1 on Solaris 8 X86 on apache, and I'm
trying to search an array




while(list($findId) = mysql_fetch_row($resultNextLast)){
$NextLast[] = $findId;
}
$currArrayPos   = array_search($ImgId, $NextLast);


and this code results this error:
Fatal error: Call to undefined function: array_search()


Any body have any idea what could be wrong?


Thanks David

From the manual: array_search (PHP 4 = 4.0.5)

$sub = abcd;

$subs[] = cde;
$subs[] = iyu;
$subs[] = abc;
$subs[] = xyx;
$match=false;
foreach($subs as $value)
{
 if($sub==$value){$match=true; break;}
}
if($match) echo 'found!';
else  echo 'not found!';

//or better use
//for PHP 4
if(in_array($sub,$subs))echo 'found!';
else  echo 'not found!';

//also possible
//for PHP 4 = 4.0.5   4.2.0
if(is_null(($b=array_search($sub,$subs  echo 'not found!';
else echo 'found! In $sub['.$b.']';
//or for  PHP 4 = 4.2.0
if(($b=array_search($sub,$subs)))  echo 'found! In $sub['.$b.']';
else echo 'not found!';

 What I was  looking for was finding out what was the index of thet
 value, lets say I have a array with some values like (23, 56, 45, 47)
 and i don't know where the walue I'm looking for is indexed in the array
 and I want to find out what the indexnumber is, how would that be
 possable

?

function array_index($array,$needle)
{
/* written by [EMAIL PROTECTED] */
foreach($array as $key=$value)
if($value==$needle)
return $key;
return -1;
}

$array=array(23, 56, 45, 47);

echo array_index($array,45);
echo array_index($array,48);
if(array_index($array,48)0)echo 'not found';
else echo 'found';
?
