Try this:

$array = file("textFile.txt");

function _trim( &$value, $key ) {
    $value = trim( $value );
}

// remove the newlines and extra spacing
array_walk( $array, '_trim' );

$replaceArray = array_fill( 0, count($array), '' );

if( isset( $_POST[ 'btcari' ] ) ) {
    echo str_replace( $array, $replaceArray, $_POST[ 'tateks' ] );
}

Hope it helps.
