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)

send earlier to this list:

<?
$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 ***@startpunt.cc */
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';
?>
