将php变量通过参数传递给javascript触发器函数PHP，JAVASCRIPT

I'm trying to pass 2 variables through a php function's parameters to be use by the javascript's trigger function but the javascript's trigger function is not accepting the 2 variables. Not sure what I did wrong. Please take a look:

trigger.php

<?php

function trigger($type,$name) {

echo "<script>";

echo "

$(function(){
  $('$type[name=$name]').trigger('change');
});

";

echo "</script>";

}

?>

The problem is that you are using " which attempt to parse the variables in the string, if you switch to ' the $ of the jQuery won't be parsed and you can concat your variables with .

function trigger($type,$name) {

echo '<script>';

echo '

$(function(){
  $(\'' . $type . '[name=' . $name . ']\').trigger(\'change\');
});

';

echo '</script>';

}
