PHP in_array无法正常工作

Question

I am creating this array from a posted textarea and splitting the lines:

$ignored = array();
foreach(explode("\n", $_POST["ignored"]) as $ignored2) {
    $ignored[] = $ignored2;
    echo $ignored2.'<br>';
}

then i have a while loop where i check if any of the array items are in a variable within the while loop:

while(($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
    //check if the description is anything in the ignore array
    if(in_array($data[6], $ignored)) {
        echo 'ignore';
    } else {
        echo 'dont ignore';
    }
}

I put the following in the textarea (one on each line):

SIP Trunk: ST17830T001 (200 channels)
SIP Trunk: ST17830T002 (1 channels)

but its only echoing 'ignore' once and its not ignoring the other item (they both exist in the $data[6] variable

Answer 1

Trim the data from the textarea:

$ignored = array();
foreach(explode("\n", $_POST["ignored"]) as $ignored2) {
    $ignored[] = trim($ignored2);
    echo $ignored2.'<br>';
}

Also trim the variable you're testing:

if (in_array(trim($data[6]), $ignored)) {
