in_array不起作用，它应该是[关闭]

Question

Alright, i've tried everything. SO is my last resort!!

heres my code:

for($i = 0; $i < 15; $i++){
    $coach = $trainergross[$i]['instr'];
    $tclub = $trainergross[$i]['club'];
    $rookcheck = "$coach $tclub";
    if(in_array(trim(strtolower($rookcheck)), $rook)){
    $pls = 'y no work';
    }
    echo "$rookcheck $pls <br>";
}

here is print_r($rook):

Array ( [0] => jess p )

and here is what echo "$rookcheck $pls <br>"; is creating

naps d
sarah c
richie e
lee b
kate e
jess p <---- WHY ISNT THIS ECHOING $PLS???
josh d
chris e

if i use in_array('jess p', $rook) it works. so is the loop breaking this? i dont know. i'm getting mad!

Thanks for your help!!

This should work for you

$trainergross = array(
        array(
                'instr' => 'naps',
                'club' => 'd',
        ),
        array(
                'instr' => 'sarah',
                'club' => 'c',
        ),
        array(
                'instr' => 'richie',
                'club' => 'e',
        ),
        array(
                'instr' => 'lee',
                'club' => 'b',
        ),
        array(
                'instr' => 'kate',
                'club' => 'e',
        ),
        array(
                'instr' => 'jess',
                'club' => 'p',
        ),
        array(
                'instr' => 'josh',
                'club' => 'd',
        ),
        array(
                'instr' => 'chris',
                'club' => 'e',
        ),
);
$rook[] = "chris e";

for($i = 0; $i < count($trainergross); $i++){
    $coach = $trainergross[$i]['instr'];
    $tclub = $trainergross[$i]['club'];
    $rookcheck = $coach.' '.$tclub;

    if(in_array(trim(strtolower($rookcheck)), $rook)){
        $pls = 'y no work';
    }
    echo $rookcheck.$pls."<br>";
}
