[Resolved] What would be the best way to search my array?

[skeetley]

Hi everyone,
I am still very new to PHP and need some help. I have a multi-dimensional array and I want to make the script search it for certain strings and if present do something. How sould I best tackle this? Use an if loop, or the search array function, or something else? The string I want to search for will always be in location $array[something][0], but i want to search for a few strings and do the same action for all of them.

Example
if $array[$i][1] = "city1" or "city2" or city3 "; $i++;
do a bunch of stuff
else $i++;

or would i use the search_array function better?

I have never really used an if loop or a search_array loop before so how best should i proceed? Thanks.

what about [man]in_array[/man]?

I just did a bit of quick reading on in_array as bastien suggested. Thanks bastien. It looks like it should work well for my application. Granted I have not done the required reading yet to try and solve this on my own, but if I use in_array and it locates a string, say 'city1' in location $array['322']['0'], how do I find out where in the array it is so I can print out $array['322']['1'], and ['322']['2'], etc?

I would check out

http://us3.php.net/manual/en/function.array-search.php

There is an example there to search in a multi-dimentional array.

OK, so from reading array_search I want to search for the value and return the key. I think anyway. I'll give this a go unless there are any other helpful suggestions.

Got it using this code:

$search_value = "YPA";

foreach ($FileArray as $key => $row)
{
     foreach($row as $cell)
     {
          if ($cell == $search_value){               

echo "Conditions at the International airport on ".$FileArray[$key][1]." at ".$FileArray[$key]['2']." UTC are:";
echo "<br>Temperature: ".$FileArray[$key][3]."&degC";
echo "<br>Dewpoint: ".$FileArray[$key][4]."&degC";
echo "<br>Relative Humidity: ".$FileArray[$key][7]."%";
echo "<br>Visibility: ".$FileArray[$key][5]." km/h";
echo "<br>Wind Direction: ".$FileArray[$key][10]."&deg";
echo "<br>Wind Speed: ".$FileArray[$key][11]." km/h";
echo "<br>Pressure: ".$FileArray[$key][14]." hPa";
echo "<br>Disclaimer: If ".$FileArray[$key][0]." does not say YPA, then this data is not for P.A.";
}
	}
}

Shouts out to bastien and dankstick for their help!!!
