PHP eregi() Function

PHP eregi() Function


Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we will be discussing about the PHP eregi() Function.

The eregi() function searches round a string specified by pattern for a string specified by string. Search with this function is not case sensitive. Eregi() can be particularly useful when checking the validity of strings, such as password.

The optional input parameter regs holds an array of all matched expressions that were grouped by parentheses in the PHP regular expression.


Syntax

The following is the syntax for the eregi() function -

int eregi(string pattern, string string, [array regs]);

Return Value

  • This PHP function returns true if the pattern is validated, otherwise false.

Example

Following is a simple example -

<?php
   $password = "abc";
   
   if (! eregi ("[[:alnum:]]{8,10}", $password))
   {
      print "Invalid password! Passwords must be from 8 - 10 chars";
   } else {
      print "Valid password";
   }
?>

Output

When the above code is executed, it will produce the following result -

Invalid password! Passwords must be from 8 - 10 chars
