Question

In my project I have array and when I echo it using pre tag it display like this.

Array
(
[0] => stdClass Object
    (
        [minute] => 1,31
        [hour] => 0-5
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 adjkerntz -a
    )

[1] => stdClass Object
    (
        [minute] => 1
        [hour] => 3
        [mday] => 1
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /etc/rc.update_bogons.sh
    )

[2] => stdClass Object
    (
        [minute] => */60
        [hour] => *
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /usr/local/sbin/expiretable -v -t 3600 sshlockout

        [hour] => *
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /usr/local/sbin/expiretable -v -t 3600 webConfiguratorlockout
    )

[4] => stdClass Object
    (
        [minute] => 1
        [hour] => 1
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /etc/rc.dyndns.update
    )

[5] => stdClass Object
    (
        [minute] => */60
        [hour] => *
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /usr/local/sbin/expiretable -v -t 3600 virusprot
    )

[6] => stdClass Object
    (
        [minute] => 30
        [hour] => 12
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/bin/nice -n20 /etc/rc.update_urltables
    )

[7] => stdClass Object
    (
        [minute] => */1
        [hour] => *
        [mday] => *
        [month] => *
        [wday] => *
        [who] => root
        [command] => /usr/local/www/checksum.php
    )

)

Now I want to check if command=/usr/local/www/checksum.php is exist or not. so, I made this code

if (!in_array('/usr/local/www/checksum.php', $array['command'])) {
    echo 'not';
}
else{
    echo 'yes';
}

But it always echo not...and warning displayed like Message: Undefined index: command. I don't know how to do it. Please help me.

Answer 1

Your array is found inside an object, so you must access the object and then the array.

You can do something like this,

if (!in_array('/usr/local/www/checksum.php', $arr[0]->obj['command'])) {
    echo 'not';
}else{
    echo 'yes';
}

Note, the [0] in this case means the first object inside your array, so you are trying to check if command exists in all of your arrays, you will have to iterate through them like this:

foreach($arr as $key => $obj){

    var_dump(in_array('/usr/local/www/checksum.php', $obj[$key]['command'])); 

}
