从静态文本自动创建电子邮件链接

I'm trying to figure out how to automatically link the email addresses contained in a simple text from the db when it's printed in the page, using php.

Example, now I have:

Lorem ipsum dolor email@foo.com sit amet

And I would like to convert it (on the fly) to:

Lorem ipsum dolor <a href="mailto:email@foo.com">email@foo.com</a> sit amet 

You will need to use regex:

<?php

function emailize($text)
{
    $regex = '/(\S+@\S+\.\S+)/';
    $replace = '<a href="mailto:$1">$1</a>';

    return preg_replace($regex, $replace, $text);
}


echo emailize ("bla bla bla e@mail.com bla bla bla");

?>

Using the above function on sample text below:

blalajdudjd user@example.com djjdjd 

will be turned into the following:

blalalbla <a href="mailto:user@example.com">user@example.com</a> djjdjd

I think this is what you want...

  //store db value into local variable
    $email = "foo@bar.com";
    echo "<a href='mailto:$email'>Email Me!</a>";

Try this version:

function automail($str){

    //Detect and create email
    $mail_pattern = "/([A-z0-9_-]+\@[A-z0-9_-]+\.)([A-z0-9\_\-\.]{1,}[A-z])/";

    $str = preg_replace($mail_pattern, '<a href="mailto:$1$2">$1$2</a>', $str);

    return $str;
}

Update 31/10/2015: Fix for email address like abc.def@xyz.com

function detectEmail($str)
{
    //Detect and create email
    $mail_pattern = "/([A-z0-9\._-]+\@[A-z0-9_-]+\.)([A-z0-9\_\-\.]{1,}[A-z])/";
    $str = preg_replace($mail_pattern, '<a href="mailto:$1$2">$1$2</a>', $str);

    return $str;
}
