Linux PHP Executable Output Issue with IE
I have developed a PHP web page that executes a batch file and pipes the output to a file. It works fine when using Firefox, Safari, etc. However, when using IE, it does not work.
$execute = `batch.bat $var1 $var2 | tee /batch.output`;
print "<pre>$execute</pre>";
When the page is run in IE, the batch file is run correctly, the variables are passed to the executable. Even the output is correct on the screen (verified using the <pre>tags). However, the file batch.output is not created when run with IE (but is with other browsers).
Suggestions?

LEARN ABOUT PHP
php_strip_whitespace
PHP_STRIP_WHITESPACE(3) 1 PHP_STRIP_WHITESPACE(3)
php_strip_whitespace - Return source with stripped comments and whitespace
SYNOPSIS
string php_strip_whitespace (string $filename)
DESCRIPTION
Returns the PHP source code in $filename with PHP comments and whitespace removed. This may be useful for determining the amount of actual
code in your scripts compared with the amount of comments. This is similar to using php -w from the commandline.
PARAMETERS
o $filename
- Path to the PHP file.
RETURN VALUES
The stripped source code will be returned on success, or an empty string on failure.
Note
This function works as described as of PHP 5.0.1. Before this it would only return an empty string. For more information on this
bug and its prior behavior, see bug report #29606.
EXAMPLES
Example #1
php_strip_whitespace(3) example
<?php
// PHP comment here
/*
* Another PHP comment
*/
echo php_strip_whitespace(__FILE__);
// Newlines are considered whitespace, and are removed too:
do_nothing();
?>
The above example will output:
<?php
echo php_strip_whitespace(__FILE__); do_nothing(); ?>
Notice the PHP comments are gone, as are the whitespace and newline after the first echo statement.
