Check if all values of keys of multidimentionnal array are numeric? - php

Question

i'm gona crazy, debuting in php..
I need to check if key value of an multidimentionnal array are all numeric..
a print_r() of my $values_arr give that:
Array ( [coco] => Array ( [0] => 18 [1] => 99 ) [chanel] => 150
I need to check if 18 and 99 and 150 are numeric, i will don't know what will in the array , and this array will not more 2 dimention.
I tryed many things, the last one..:
foreach ( $values_arr as $foo=>$bar ) {
if( !in_array( $foo, $_fields_arr ) || !is_numeric($bar ) ) {
echo "NOTGOOD";
}
}
****UPDATE****
new test :Here because chanel isnot int , this exemple should be echo "not goud",
but its not the case..
$_fields_arr = array('coco','chanel','other');
$ary = array(
'coco' => array(18, 99),
'chanel' => 'yu'
);
function allIntValues($o)
{
if (is_int($o)) return true;
if (is_array($o)){
foreach ($o as $k => $v) {
if (!is_int($v)) return false;
}
}
return true;
}
foreach ($ary as $k => $v) {
if (!in_array($k, $_fields_arr) || !#allIntValues($v)){
echo "notgood";
}
else echo "good";
}
thanks for any help,
regards

Update:
$ary = Array(
'coco' => array(18, 99),
'chanel' => 150
);
$_fields_arr = array('coco', 'chanel');
function allIntValues($o)
{
if (is_int($o)) return true;
if (is_array($o)){
foreach ($o as $k => $v) {
if (!is_int($v)) return false;
}
}
return true;
}
foreach ($ary as $k => $v) {
if (in_array($k, $_fields_arr) && #allIntValues($v)){
// $ary[$k] is no good
}
}
Assuming you want to test if all values are numeric (despite how deep the value's nested):
function is_numeric_array($ary)
{
foreach ($ary as $k => $v)
{
if (is_array($v))
{
if (!is_numeric_array($v))
return false;
}
else if (!is_numeric($v))
return false;
}
return true;
}
That will (recursively) check the array and make sure every value is numeric within the array.
array(1,2,3) // true
array('foo','bar','baz') // false ('foo', 'bar' & 'baz')
array(1,2,array(3,4)) // true
array(array(1,'foo'),2,3) // false (foo)
array("1,", "2.0", "+0123.45e6") // true

You are using the value instead of the key:
if( !in_array( $bar, $_fields_arr ) || !is_numeric($foo ) ) {
