I am trying to call a javascript function from php. According to all of the examples I have been looking at the following should work but it doesn't. Why not?
<?php
echo "function test";
echo '<script type="text/javascript"> run(); </script>';
?>
<html>
<script type="text/javascript">
function run(){
alert("hello world");
}
</script>
</html>

Your html is invalid. You're missing some tags.
And you need to call the function after it has been declared, like this
<html>
<head>
<title></title>
<script type="text/javascript">
function run(){
alert("hello world");
}
<?php
echo "run();";
?>
</script>
</head>
<body>
</body>
</html>
In this case you can place the run before the method declaration, but as soon as you wrap the method call inside another script tag, the script tag has to be after the method declaration.

the function must declare before use
it should be
<html>
<script type="text/javascript">
function run(){
alert("hello world");
}
<?php
echo "function test";
echo run(); ;
?>
</script>
</html>
