PHP output JavaScript script with PHP parameter, function argument string with variable

1, in PHP, sometimes we need to echo out the JS script, and this script with PHP settings variables

How to output, a bit fastidious, write down to spare. Here's how:

(1) The first method

<?php

$_HG = ' Hong ';

Echo ' <script type= "Text/javascript" >alert ("My name is '. $_hg. '"); History.back ();</script> ';

?>

(2) The second method, the implementation of changing single quotation marks, the quotation of double quotes <?php $_hg = ' Hong '; echo "<script type= ' text/javascript ' >alert (' My name is '. $_hg. '); </script> ";? >

2. We encapsulate the above PHP code into a function, passing in arguments with strings

$_hg= ' Hong ';

function _alert_look ($_hh) {

echo "<script type= ' text/javascript ' >alert ('". $_hh. "); </script> ";

}

We call the function to do this:

_alert_look ("My Name is". $_hg. " Complete! ");
