ereg() and eregi() functions

[Japher]

Q: 1
I used the eregi() function to search a particular string pattern in
a string.
The following coding does give an output , please debug! 🙂

<?php

$str1 = "mow pow";

if(eregi("[[:<:]](a-zA-Z)*ow[[:>:]]", $str1,  $match))
{

print("word found ending in 'ow'". $match[1]. "<br />");
}

?>

Q2:

How amny arguments does the ereg() takes? does it take an
array variable as it's third arguement?

[bubblenut]

if( preg_match('/\\b([a-zA-Z]*ow)\\b/', $str1, $matches) ) {
  print("word found ending in 'ow'".$matches[1]."<br />");
}
