I have this array:
Array
(
[2] => Array
(
[sex] => 1
)
[295] => Array
(
[sex] => 1
)
[901] => Array
(
[sex] => 1
)
[1550] => Array
(
[sex] => 1
)
[1570] => Array
(
[sex] => 1
)
[1715] => Array
(
[sex] => 1
)
[1764] => Array
(
[sex] => 1
)
[1784] => Array
(
[sex] => 1
)
[1835] => Array
(
[sex] => 1
)
[1849] => Array
(
[sex] => 1
)
[1855] => Array
(
[sex] => 1
)
[1873] => Array
(
[sex] => 2
)
[1885] => Array
(
[sex] => 1
)
[1888] => Array
(
[sex] => 2
)
[1908] => Array
(
[sex] => 1
)
[1910] => Array
(
[sex] => 2
)
[1915] => Array
(
[sex] => 1
)
[1916] => Array
(
[sex] => 1
)
)
I would like to output in other array IDs that have sex value 1???
Thanks buddy but how do I use this?
click on the links and scroll down to the examples’ section.
Please give me quick example please?
function odd($var)
{
// returns whether the input integer is odd
return($var & 1);
}
$array1 = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);
echo "Odd :\n";
print_r(array_filter($array1, "odd"));
Thanks but I don’t see how I can apply it to my array? Please could you use my array in your example?
how about you give it a try yourself?
Buddy I am a newbie in PHP. I don’t get it please?
How do I remove array that has sex value 2 from this array
“newbie” doesn’t mean you shouldn’t attempt it yourself first.

I am testing but I doesn’t seems to work!
from the Manual of array_filter():
Iterates over each value in the array passing them to the callback function. If the callback function returns true, the current value from array is returned into the result array.
I am more visual learner please give me a hand please?
if you have code to test, you can post it here, so we can see where the problem is.
function odd($var)
{
// returns whether the input integer is odd
return($var & 1);
}
echo "Odd :\n";
print_r(array_filter($test, "odd"));

Doesn’t remove array that have sex value 1
why do you test for the odd-ness of each sub-array, when you want to test the value for the sex key?
letsforum:
What is $var ???
$var is each array element that is tested.
I get no idea what I am doing?
