如何在JavaScript中提醒PHP值？

Question

<script type="text/javascript">
    var jvalue = 'this is javascript value';
    <?php $abc = "<script>document.write(jvalue)</script>" ?>
</script>

<?php echo  'php_'.$abc; ?>

<script type="text/javascript">
    var test="<?php echo $abc; ?>";
</script>

<?php
    echo '<script language="javascript">';
     echo 'alert(test)';
     echo '</script>';
 ?>

How to alert test variable, which contains php value ? I would like to get the php value in javascript, for further execution in my project.

Answer 1

why are you assigning the variable to a javascript variable and then echoing that? sounds like extra work to me...

echo 'alert("' . $abc . '");';
