Second Example
Second example:
Just create a file named dict.php under the tree /var/www and copy the following content in it:
<html><head>
<title>
Dictionary search using "dict"
</title>
<style type="text/css">
A { text-decoration:none; }
A:hover { color: #800080; font-weight:bold; }
input {
border: 1px solid black;
padding-right:4px;
padding-left:4px;
}
</style>
</head>
<body>
<script language="JavaScript">
function processLink(s)
{
s = s.replace(/\s+/g," ");
location.href=self.name + "?query=" + escape(s);
}
</script>
<form name="form1">
Enter word for "dict" search: <input value="<?php
$query = $_REQUEST['query'];
# clean up passed value
$query = preg_replace("/^\s+/","",$query);
$query = preg_replace("/\s+$/","",$query);
$query = preg_replace("/\s+/"," ",$query);
$value = preg_replace("/\"/",""",$query);
echo "$value"
?>" type="text" name="query" onChange="submit()"><p>
</form>
<?php
if($query != "") {
$equery = escapeshellarg($query);
exec("/usr/bin/dict $equery 2>&1",$output,$error);
$output = implode("\n",$output);
if($error) {
echo "<pre><b>Error: $output<b></pre>";
}
else {
if (preg_match("/no definitions found/i",$output)) {
# turn suggested alternatives into links
$output = preg_replace("/(: +)(\w+)/",
"\\1<a href=\"javascript:processLink('\\2');\">\\2</a>",$output);
echo "<pre>$output</pre>";
}
else {
# bold first line
$output = preg_replace("/^(.*)/","<b>\\1</b>",$output);
# wrap first line of each reference in table to control background color
$output = preg_replace("/(\n\nFrom )(.*)\n/","\n\n<table cellpadding=4
bgcolor=#d0d0ff><tr><td><b>\\2</b></td></tr></table>",$output);
# find and process document internal links
$output = preg_replace("/\{+(.*?)\}+/s",
"<a href=\"javascript:processLink('\\1');\">\\1</a>",$output);
echo "<pre>$output</pre>";
}
}
}
?>
<script language="JavaScript">
document.form1.query.focus();
</script>
</body>
</html>
