How would you translate this in PHP ?

[Porsche_maniak]

For first value in $var do something...


I think it is subarray.. like - $entry_array[ 'entry' ] .. So t3od0r how to choose the first or any other value.. And btw the values are actually all entries/pages of content.

I think if($entry_array[ 'entry' ][0]) works but if i want to do this ---

if($entry_array[ 'entry' ][0]){$entry_array[ 'entry' ][0]=$entry_array[ 'entry' ][0].'TEST';}
it adds 'TEST' to all entries not the first one...(maybe because the code like this means 'if exist'?)

Wat is $var
an array, phrase...

[t3od0r]

first value in $var?
then $var is an array right? $var = array("1","2","3");
first value : $var[0] -> will show 1

I think he want to do something with firs array value, not sure about that.

Depends on the keys used for the elements in the array. Keys, by default, are incrementing integers.

// Incremental integer keys assigned by PHP
$fruits = array( 'Apple', 'Orange', 'Banana' );

echo $fruits[0];
// Output: Apple

echo $fruits[1];
// Output: Orange 

// Explicitly assigned keys
$fruitColors = array(
    'Apples' => 'red',
    'Oranges' => 'orange',
    'Bananas' => 'yellow'
);

echo $fruitColors[ 'Apple' ];
// Output: red

foreach( $fruitColors as $fruit => $color )
{
    echo $fruit . ' are <span style="color:' . $color . ';">' . $color . '</span>.<br />' . "\n";
} 

Output:

Apples are red.
Oranges are orange.
Bananas are yellow.

[litewarez]

$result = (isset($var[0]) ? $var[0] : null); 

by the way you explained it you might want

for($i=0;$<=count($var);$i++)
{
    switch($i)
    {
        case 0:
            //First item here
            $var[$i] = strtolower($var[$i]);
        break;
        default:
            //All other elements in the array
            $var[$i] = strtoupper($var[$i])
        break;
    }
}

Isn't he talking about multidimensional arrays?

[el_jentel1]

Then we have multidimensional arrays.

// Two-dimensional array
$produce = array(
    'fruits' => array( 'Apples', 'Oranges', 'Bananas' ),
    'vegs' => array( 'Tomatos', 'Potatos', 'Carrots' )
);

echo $produce[ 'fruits' ][0];
// Output: Apples

echo $produce[ 'vegs' ][2];
// Output: Carrots 

[litewarez]

Multidimensional arrays still have an index of numerics as well as strings so example

$user = array(
    'dob' => 25121988,
    'age' => 21,
    'profile' => array(
        'username' => 'litewarez'
    )
);

$profile_1 = $user['profile']; //array(username ...)
$profile_2 = $user[2]; //array(username ...)

//the same 

try do this

print_r($entry_array);
