Trim should do exactly what you're looking for without needing
ereg_replace, etc.
Trim trims all whitespace before the first non-whitespace character and
after the last non-whitespace character. I've included an example and
its output below.
File: test.php
<?php
header("Content-type: text/plain");
$test_str = " This is my test str ";
echo "'$test_str'\n\n";
$test_str = trim($test_str);
echo "'$test_str'";
?>
Output: test.php
' This is my test str '
'This is my test str'
Note: The single quotes are included in the output to show where the
spaces are.
Hope this helps!
