PHP对两个数组

How do you grab two arrays and list them as key pairs separated by commas.

Array1
    'key1a'=>'value'
    'key2a'=>'value'
    'key3a'=>'value'

Array2
    'key7b'=>'value'
    'key8b'=>'value'
    'key9b'=>'value'

Desired output:

key1a = key7b, key2a = key8b, key3a = key9b

$new_Array = array_combine(array_keys($Array1), array_keys($Array2));

$newarr = array_combine(array_keys($arr1), array_keys($arr2));

This should do given that $arr1 and $arr2 are the same length.

$array1 = array('key1a'=>'value',
'key2a'=>'value',
'key3a'=>'value');

$array2 = array('key7b'=>'value',
'key8b'=>'value',
'key9b'=>'value');

$keys = array_combine(array_keys($array1),array_keys($array2));
foreach($keys as $k => $k2) echo " $k = $k2".($k2==end($keys)?'':',');

DEMO VIEW

foreach($arr1 as $i => $val){
    foreach($arr2 as $j => $val2){
    echo $i . " = " . $j . ", ";
    }
}

This works, though probably not what you're looking for (because you commented that you were trying to do it without loops?) Keep in mind, array_combine() is a PHP5 function.

I was thinking of this:

implode(', ', array_map(create_function('$k1,$k2', 'return $k1 . " = :" . $k2;'), array_keys($array1), array_keys($array2)))
