I believe preg_match should be used. What will be the code? Thank you.


1) if(ereg("^[A-Za-z0-9_]{1,255}$",$this->username))

2) if(eregi("^[https?://.+\..+]{1,255}",$this->url))

3) if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$",$this->email))

4) if(ereg("^[0-9]{1,6}$",$this->hits))

5)   if(eregi("^[https?://.+\..+]{1,255}",$this->url)
&& eregi("[.+\@.+\..+]{1,255}",$this->email)

Usually this is as simple as changing to preg_match() by adding a regex delimiter and the appropriate flags.  Example:

"^[https?://.+\..+]{1,255}" for eregi() would become
"#^[https?://.+\..+]{1,255}#i" for preg_match()

Another example...
if(ereg("^[0-9]{1,6}$",$this->hits)) would become something like this:
"/^[0-9]{1,6}$/"

You may fine it easier to make the conversion if you write out the regular expressions in a way that self-explains the expression.  Example:
$rgx 
= '/'        // REGEX DELIMITER
. '^'        // AT START OF THE STRING
. '[0-9]'    // CHARACTER CLASS OF DIGITS ONLY
. '{1,6}'    // WITH LENGTH OF 1-6 CHARACTERS
. '$'        // AT END OF STRING
. '/'        // REGEX DELIMITER
;

Here's another example.  Original ereg() expression:
"^[A-Za-z0-9_]{1,255}$"

Updated for preg-type expressions:
$rgx
= '#'       // REGEX DELIMITER
. '^'       // AT START OF STRING
. '['       // START CHARACTER CLSS
. 'A-Z'     // UPPER CASE ALPHA
. 'a-z'     // LOWER CASE ALPHA
. '0-9'     // NUMERIC DIGITS
. '_'       // THE UNDERSCORE
. ']'       // END OF CHARACTER CLASS
. '{1,255}' // LENGTH FROM 1 TO 255
. '$'       // AT END OF STRING
. '#'       // REGEX DELIMITER
;
