Array to string

[cobusbo]

Hi I'm trying to create an array to put it into a string like the following

$marray = array(

    '1' => 'apple,',

    '2' => 'orange,',

    '3' => ' ',

    '4' => ' ',

    '5' => 'apple');

 

And the string should look like

 

       $mrules = "Welcome Moderator please read the following rules. " . 1. Apple, 2. Orange, 5. Apple.

 

The empty values in the array shouldn't be showed

 

any assistance please

$marray = array(

    '1' => 'apple,',

    '2' => 'orange,',

    '3' => ' ',

    '4' => ' ',

    '5' => 'apple');


//just values

$trimmedArray = array_filter(array_map('trim', $marray));

$mrules = "Welcome Moderator please read the following rules. ".implode(" ",$trimmedArray);


echo $mrules."<br />";


//alternate if need keys

$mrules = "Welcome Moderator please read the following rules. ";

foreach($marray as $key=>$value){

	if(trim($value) !=''){

		$mrules .= $key.". ".$value." ";

	}

}


echo $mrules;

Ah thank you after making a few changes I got it working

$marray = array(
    '1' => 'apple',
    '2' => 'orange',
    '3' => ' ',
    '4' => ' ',
    '5' => 'apple');
$tmp = array_filter(array_map('trim', $marray));  // remove blanks
$str = '';
foreach ($tmp as $k=>$v) {
    $str .= "$k. $v, ";
}       

$mrules = "Welcome Moderator please read the following rules. " . $str;  ///=> Welcome Moderator please read the following rules. 1. apple, 2. orange, 5. apple,
