Extract a part of keys values in array php -

for reason have array of kind, , want extract 2 first part of each key,some of key contain 5 pieces of string separated ',' while other contain 2 pieces of string separated y ',' ex:

array (     'kksgzgg , kdhdhk',     'jjj , jjd , jsjs , sjsj , jjsjs',     'kksksk , kdkdkk',     'jjj , jjd , jdjdjdj , jjd , jdjdjddj',     'jjj , jjd , jdjdj , jjsj , sjsjsj',     'jjj , jjd' ); 

i need result 2 elements in each key(separated comma):

array (      [0] => kksgzgg , kdhdhk      [1] => jjj , jjd       [2] => kksksk , kdkdkk       [3] => jjj , jjd       [4] => jjj , jjd       [5] => jjj , jjd   )  

thank help

you can following functions:

• implode — join array elements string
• explode — split string string
• array_slice — extract slice of array

example:

$newarray = array(); foreach ($oldarray $value) {     $newarray[] = implode(',', array_slice(explode(',', $value, 3), 0, 2)); }  print_r($newarray); 

output:

array (     [0] => kksgzgg , kdhdhk     [1] => jjj , jjd      [2] => kksksk , kdkdkk     [3] => jjj , jjd      [4] => jjj , jjd      [5] => jjj , jjd ) 

explanation:

the code inside foreach can rewritten temp variables, makes easier understand what's happening. following code equivalent one-liner above:

$parts         = explode(',', $value, 3); $subsetofparts = array_slice($parts, 0, 2); $gluedtogether = implode(',', $subsetofparts); $newarray[]    = $gluedtogether; 

these 4 lines applied values in array 1 one during foreach. let's assume doing this $value:

'jjj , jjd , jsjs , sjsj , jjsjs' 

the first line split value comma. third argument 3 controls how many elements in $parts:

[0 => 'jjj ', [1] => ' jjd ', [2] => ' jsjs , sjsj , jjsjs'] 

the second line create new array $parts contains first , second elements, result be

[0 => 'jjj ', [1] => ' jjd '] 

the third line glue the subset of parts comma,

'jjj , jjd' 

that string added $newarray.
