Replacing all alpha numeric characters with Space
<?php
$input=”@This@is%test !String&with*Spaces-”;
echo $input;
$output=trim( ereg_replace( “[^[:space:]a-zA-Z0-9]”, ” “, $input ) );
echo ‘<br>’;
echo $output;
?>
In above example, we can replace all characters except alphabets and numerics with space using ereg_replace.
