[display php variable in alert box]

The example you provided is running fine.

 

However, I want to display the contents of a file.

 

<?php
$fh = fopen("example.txt", "r");
              while (!feof($fh))
              {
                       $line = fgets($fh);
                       $file = $file . $line;
              }
                fclose($fh);
echo "<script type='text/javascript'>alert('{$file}');</script>";
?>

 

but the alert box is not appearing...can u suggest sumthin?  :'(

 

It seems that it only works if there's only one line in the file. Maybe the hidden \r\n character (it is used in edit controls in the C++ Win32 API, which is what Notepad.exe was made in, for a new line) in the text is messing it up. Because I can echo it to the screen fine:

 

<?php
$fh = fopen ("example.txt", "r");
while (!feof ($fh))
{
     $file = $file . fgets ($fh) . "</br>";
}
fclose ($fh);
echo $file;
?>

 

Just not use the alert function =/

 

So, not sure on this one, maybe someone else can help you out.

[display php variable in alert box]

does alert function have to defined in the php page?

 

alert is pre-defined rite?

 

echo "<script type='text/javascript'>alert('{$variabl}');</script>

 

the alert box does not appear...

 

alert if a Java Script function, so it doesn't have to be defined on the PHP page. And what he said works fine besides the fact that he forgot the ending quote after </script>

 

<?php
$Text = "Hello World!";
echo "<script type='text/javascript'>alert('{$Text}');</script>"
?>

 

haha we both messed up, you forgot a ; at the end..

 

sorry btw @OP I can't really see too well you have to pardon my crappy help

 

<?php
$Text = "Hello World!";
echo "<script type='text/javascript'>alert('{$Text}');</script>";
?>

 

Ooops, well that's embarrassing
