$newDataArray = array_filter($dataArray, create_function('$a','return

If I have an array like this
$dataArray = array(0=>array('type'=>'da'), 1=>array('type'=>'wb'), 
2=>array('type'=>'da');

How I can filtering to get only 'da' only, like this 


$newDataArray = array(0=>array('type'=>'da'),2=>array('type'=>'da'))


Off the top of my head:

 $v) {
if (!empty($v['type']) AND $v['type'] != 'da') {
unset($newDataArray[$k]);
}
}
?>

Optionally, you could use array_values() to re-index $newDataArray if 
you need to.

[PHP] array_filter function

[Bagus Nugroho]

Hello,

If I have an array like this
$dataArray = array(0=>array('type'=>'da'), 1=>array('type'=>'wb'), 
2=>array('type'=>'da');

How I can filtering to get only 'da' only, like this 

$newDataArray = array(0=>array('type'=>'da'),2=>array('type'=>'da'))

Thanks in advance

[PHP] array_filter

[David Otton]

I suspect this can't be done in PHP. However...

Is it possible to pass additional parameters to the callback function
used by array_filter()?

I guess I'm looking for something functionally equivalent to this Python
code:

from string import count

list = ('apple', 'avacado', 'banana', 'blueberry', 'peach', 'persimmon')
strings = ['a', 'b', 'c', 'd', 'e', 'f']

for string in strings :
print filter(lambda x : count(x, string), list)
