php re-create an array to new keys and values
I have the following array of keys and values. How can i rec开发者_运维技巧reate this array to make the second column as the key and 3rd column the values. Also remove all unwanted spacings.
Array
(
[16] => hasKeyframes : true
[17] => hasMetadata : true
[18] => duration : 30
[19] => audiosamplerate : 22000
[20] => audiodatarate : 68
[21] => datasize : 1103197
}
New array should look like this.
Array
(
[hasKeyframes] => true
[hasMetadata] => true
...
}
$newArray=array();
foreach($array as $value)
{
$pair=explode(":",$value);
$newArray[trim($pair[0])] = trim($pair[1]);
}
EDIT
if we have something like [19] => Duration: 00:00:31.03, then we only get 00 for $pair[1]
$newArray=array();
foreach($array as $value)
{
$pair=explode(":",$value,2);
$newArray[trim($pair[0])] = trim($pair[1]);
}
My solution uses array_walk()
and works from PHP 5.3 because of the anonymous function used.
$array=array(/* ORIGINAL ARRAY */);
$newarray=array();
array_walk($array, function ($v, $k) use (&$newarray) {
$pos=strpos($v, ':');
$newkey=substr($v, 0, $pos);
$newvalue=substr($v, $pos+1);
$newarray[$newkey]=$newvalue;
});
