- 2007/09/12 The three simplest regular expressions you will use in PHP
The javascript browser snifer makes an extensive use of Regular Expressions and the search() and match() functions.
By this function, you can know following information:
[1] browser type
[2] browser version
[3] os type
[4] os version
[5] flash installation information
Actually this script is effective when making web log.
The following is the example of Javascript based Browser Sniffing.
<script type="text/javascript" src="js/brwsniff.js"></script>
<script type="text/javascript">
var br=new Array(4);
var os=new Array(2);
var flash=new Array(2);
br=getBrowser();
os=getOS();
flash=hasFlashPlugin();
document.write("Browser identifier: "+br[0]+"<br />");
document.write("Browser version: "+br[1]+"<br />");
document.write("Browser major version: "+getMajorVersion(br[1])+"<br />");
document.write("Browser minor version: "+getMinorVersion(br[1])+"<br />");
document.write("Browser engine: "+br[2]+"<br />");
document.write("Browser engine version: "+br[3]+"<br />");
document.write("Full user agent string: "+getFullUAString()+"<br />");
document.write("Operating system identifier: "+os[0]+"<br />");
document.write("Operating system version: "+os[1]+"<br />");
document.write("Is Flash installed? " + (flash[0]==2 ? "Yes" : (flash[0] == 1 ? "No" : "unknown")) + "<br />");
document.write("Flash version: "+flash[1]+"<br />");
</script>

Here's JavaScript based Regular Expression Tester.
JavaScript (or Microsoft's variant JScript) will need to be enabled in your browser.
Actually this test program is not proper for you to test the complex combination of Regular Expression supported by RegExp function.
function frm1Click()
{
var re = new RegExp(document.frm1.regex.value);
if (document.frm1.subject.value.match(re)) alert("Successful match");
else alert("No match");
}
function show()
{
var re = new RegExp(document.frm1.regex.value);
var m = re.exec(document.frm1.subject.value);
if (m == null) alert("No match");
else
{
var s = "Match at position " + m.index + ":\n";
for (i = 0; i < m.length; i++) s = s + m[i] + "\n";
alert(s);
}
}
function frm1_replace_Click()
{
var re = new RegExp(document.frm1.regex.value, "g");
document.frm1.result.value =
document.frm1.subject.value.replace(re,
document.frm1.replacement.value);
}
// -->
</script>
<form id="frm1" name="frm1" method="post" action="javascript:void(0)">
RegExp<br>
<textarea cols="50" rows="4" name="regex">l(.*?)e</textarea><br />
Subject string<br>
<textarea cols="50" rows="4" name="subject">I love you.</textarea><br />
<p><input value="Test Match" onclick="frm1Click()" type="submit">
<input value="Show Match" onclick="show()" type="submit"></p>
Replacement text<br>
<textarea cols="50" rows="4" name="replacement">hate</textarea><br />
Result<br>
<textarea cols="50" rows="4" name="result">click the button to see the result</textarea><br />
<input value="Replace" onclick="frm1_replace_Click()" type="submit">
</form>

The three most basic searches using Regular Expressions are searching for the strings start, the strings end, or for characters it contains. We can do these using the following symbols:
^ indicates the string starts with the specified characters, so "^strcpy" would match any string starting with "strcpy". This would match "strcpy.com is nice" or "strcpy the pirates" but would not match "out and strcpy".
$ indicates that a string finishes with the specified characters, so "strcpy$" would match any string that ended with "strcpy". This what match "What is it strcpy" or "Out and strcpy" but would not match "strcpy.com is nice"
"strcpy" looks for the characters specified within the quotes, anywhere within the string.
This means not only would it match "strcpy.com is nice" and "out and strcpy" it would match "Something about Mary"
These can be combined and used together. Let's say that you only wanted to match the word strcpy, and not any sentances it may be contained in. You might try combining start and end searches like this:
"^strcpy$" This would match only strings that both start and end with strcpy, which applies to a the word "strcpy".
