[PHP] Array - Match

[N. Pari Purna Chand]

I have $sub = abc;

and

$subs[0] = cde;
$subs[0] = iyu;
$subs[0] = abc;
..
..
..
$subs[50] = xyx;

How to find whether $sub matches with any one of $subs[$i]
I have used a for loop but it is
returning true when $subs[$i] = xabc.

?
$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!';
?

Hello Chandu,

You can use in_array(needle, haystack) for this. For example,

if (in_array(abc,$subs)) {item found, do stuff...}

HTH!
