[RESOLVED] searching array for value

[kbc1]

Hi all

I have an array structure as such:

Array
(
    [1] => Array
        (
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4
            [5] => 5
            [6] => 6
            [8] => 8flight
        )

)

I loop through that array and assign the values to a session array as such:

if (!empty($chosenextras)) {
	foreach($chosenextras as $key => $value) {
		$_SESSION['S_CHOSEN_EXTRA'][$key] = $value;
	}
}

Now, what I need is to search the values of the array and detect if the word 'flight' is there for any elementsa (as it will be optional).

If the word 'flight' is detected, I need to remove it completely and leave only the number which would leave me with the following array:

Array
(
    [1] => Array
        (
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4
            [5] => 5
            [6] => 6
            [8] => 8
        )

)

Please note, the word 'flight' could be in any element of the array, not just KEY[8]

Any help would be greatly appreciated.

It would be good if you specified how exactly might 'flight' be detected. For example, will it always come after the number?

For example:

<?php

$array = array(1 => 1, 2, 3, 4, 5, 6, 8 => '8flight');

foreach ($array as $key => $value) {
    if (preg_match('/(\d+)flight/', $value, $matches)) {
        $array[$key] = $matches[1];
    }
}

print_r($array);

Hi laserlight

Yes, the word flight will always appear after the number.

I tried your code on the array and the word flight was not removed:

Here is my code:

if (!empty($chosenextras)) {
	foreach($chosenextras as $key => $value) {
		if (preg_match('/(\d+)flight/', $value, $matches)) {
			$_SESSION['S_CHOSEN_EXTRA'][$key] = $matches[1];
		} else {
			$_SESSION['S_CHOSEN_EXTRA'][$key] = $value;
		}
	}
}

echo "<pre>";
print_r($_SESSION['S_CHOSEN_EXTRA']);
echo "</pre>";
exit;

Any thoughts?

laserlight's code works

but your array $chosenextras contents is really array[1]

so this I think can work

if (!empty($chosenextras)) {
    session_start();
    foreach($chosenextras[1] as $key => $value) {
        if (preg_match('/(\d+)flight/', $value, $matches)) {
            $_SESSION['S_CHOSEN_EXTRA'][$key] = $matches[1];
        } else {
            $_SESSION['S_CHOSEN_EXTRA'][$key] = $value;
        }
    }
}

echo "<pre>";
print_r($_SESSION['S_CHOSEN_EXTRA']);
echo "</pre>";
exit;

Hi halojoy

The array could end up being like this though:

Array
(
    [1] => Array
        (
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4
            [5] => 5
            [6] => 6
            [8] => 8flight
        ),
    [2] => Array
        (
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4flight
            [5] => 5
            [6] => 6
            [8] => 8
        ),
 [3] => Array
        (
            [1] => 1
            [2] => 2flight
            [3] => 3
            [4] => 4
            [5] => 5
            [6] => 6
            [8] => 8
        )

)

Any thoughts?

I have used this and it seems to work:

$_SESSION['S_FLIGHT_REQUIRED'] = false;
		$pattern = array('/flight/');
		$replace = array('');

	if (!empty($chosenextras)) {
		foreach($chosenextras as $key => $value) {
			foreach($value as $v) {
				if (preg_match('/(\d+)flight/', $v, $matches)) {
					$_SESSION['S_FLIGHT_REQUIRED'] = true;
				}
			}
			$_SESSION['S_CHOSEN_EXTRA'][$key] = preg_replace($pattern, $replace, $value);
		}
	}

I'll run with that until I hit a brick wall. :o)

thanks for all your help.

If the array can be an n-dimensional array (where n isn't known or defined), you could recursively iterate through the nested arrays using code like:

function clean_array($value)
{
  echo "value: $value\n";
  if(is_array($value))
    return array_map('clean_array', $value);
  else
    return preg_replace('/(?<=\d)flight/', '', $value);
}

$array = array_map('clean_array', $array);
