How to fix ‘Function eregi() is deprecated’ in PHP 5.3.0?

I used to use eregi for validating email address input that matches to the regular expression.

[raw]<pre>
if(!eregi("^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$", $str)) {
    $msg = 'email is not valid';
}
else {
$valid = true;
}</pre>
<p>[/raw]

That would return true if given email address is matches to username@domain.ext pattern. Unfortunately, after upgrading PHP to the earlier version (5.3.0), it wont work properly. This is because eregi is one of several functions that are deprecated in the new version of PHP.

Solution how to fix Function Deprecated:

Use preg_match with the ‘i’ modifier instead. i means that regular expression is case insensitive. So the code become like this:

[raw]<pre>
if(!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $str)) {
    $msg = 'email is not valid';
}
else {
$valid = true;
}</pre>
<p>[/raw]

The list of functions that are deprecated in PHP 5.3.0:

  • call_user_method() (use call_user_func() instead)
  • call_user_method_array() (use call_user_func_array() instead)
  • define_syslog_variables()
  • dl()
  • ereg() (use preg_match() instead)
  • ereg_replace() (use preg_replace() instead)
  • eregi() (use preg_match() with the ‘i’ modifier instead)
  • eregi_replace() (use preg_replace() with the ‘i’ modifier instead)
  • set_magic_quotes_runtime() and its alias, magic_quotes_runtime()
  • session_register() (use the $_SESSION superglobal instead)
  • session_unregister() (use the $_SESSION superglobal instead)
  • session_is_registered() (use the $_SESSION superglobal instead)
  • set_socket_blocking() (use stream_set_blocking() instead)
  • split() (use preg_split() instead)
  • spliti() (use preg_split() with the ‘i’ modifier instead)
  • sql_regcase()
  • mysql_db_query() (use mysql_select_db() and mysql_query() instead)
  • mysql_escape_string() (use mysql_real_escape_string() instead)
  • Passing locale category names as strings is now deprecated. Use the LC_* family of constants instead.
  • The is_dst parameter to mktime(). Use the new timezone handling functions instead.

    Depreciated functions are really a pain, I hope there are no more of these in the next releases.

    Sometimes it is better to use explode() instead of suggested split() —> preg_split()

    • takien

      yeah, sometimes explode is much easier and may be faster

  • dade

    so how do I fix this? I have searched and when I do apply the changed I still get an error. any assistance would greatly be appreciated.

    if ( eregi( ‘index.php\?’, $row->link ) ) {
    if ( !eregi( ‘Itemid=’, $row->link ) ) {
    $row->link .= ‘&Itemid=’. $row->id;
    }
    }

  • mike

    If you haven’t solved it yet…

    Sounds like a joomla template error change to:

    if ( explode( ‘index.php\?’, $row->link ) ) {

    if ( !explode( ‘Itemid=’, $row->link ) ) {
    $row->link .= ‘&Itemid=’. $row->id;
    }
    }

    if(!preg_match(“/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i”, $str))

    this work fine in php 5.3..

    thankjs for solving

  • BandenX

    Ayo ramai2 gunakan PHP 5.2.x. Dah bosen gw pake PHP 5.3.x. Permasalahan deprecated function nggak ada solusi yg bener2 menyelesaikan masalah

    • takien

      wah, apa gak salah tuh keputusannya untuk mengingalkan PHP 5.3.x?
      Deprecated itu bukanlah masalah besar, hanya kode kita saja yang perlu di update (disesuaikan dengan perkembangan zaman), nanti di PHP 6, fungsi2 yang deprecated tersebut benar2 tidak ada lagi.
      ya, karena sudah ada fungsi lain yang sejenis yang bisa menggantikannya, biasanya lebih lengkap/mudah dsb.

    • websoldier

      Waduh kayaknya kamu masih pemula yah??

      Namanya pemula harusnya belajar, siap menghadapi tantangan versi baru. Karena versi lama bisa jadi boomerang tersendiri bagi kamu. Lah, yg satu ini malah aneh, ada-ada aja kamu malah pengen migrasi ke versi sebelumnya.

      Sebenernya kalo kamu mempelajari apa yang ada pasti masalah-masalah itu pasti bisa dibereskan,

      Salah satunya adalah masalah migrasi function deprecated ini, ini sebenarnya masih mudah loh masih bisa dengan mudah diselesaikan dibanding persoalan bug/vulnerability/error.

      Coba anda bayangkan persoalan error/bug/vulnerability codding itu, bukankah lebih rumit??

      So, belajar coding lah anda untuk mematangkan skill walaupun “Trial & Error”, jangan cuma “script kiddies” semata.

  • marek

    you can use ‘@’ (at sign) to suppress errors that would be generated from that expression.
    e.g:
    [php]
    if(!@preg_match(“/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i”, $str))
    [/php]
    then the errors won’t show up

    Can anyone helpt me with this?

    foreach($bad as $b) {
    if(eregi($b, $this->message)) {
    $this->naughty = true;
    }
    }

    If I replace “eregi” with “explode” I do not have the error anymore but I do not receive the mail either.

    If I replace “eregi” with “preg_match” I get this error
    “Warning: preg_match() [function.preg-match]: Delimiter must not be alphanumeric or backslash in /mnt/users/oopsydai/public_html/contact/process_form.php on line 109″
    BUT the mail is received.

    Any ideas would be highly apreciated!

  • http://www.oopsydaisy.ro/contact Puiu Darlea

    I got it the right way, I am posting it in case others are in the same situation:

    if(eregi($b, $this->message))
    becomes:
    if(preg_match(“/\b”.$b.”\b/i”, $message))

    All the best to all!
    P.

    • takien

      Hello, Puiu Darlea. I was just about to reply to your comment but then you have found the solution. :D
      Furthermore, you need to use preg_quote in case your $b may contains special regex characters.

      good luck :)

    Hi Takien, and THANK you for beeing present!

    Since I am no programmer, you mean simply change “preg_match” to “preg_quote” ?

    Some one helped me with this so I do not know the implications :)

    Thanks again for beeing present on this forum!
    Puiu

    • takien

      Sorry, I wasn’t so clearly explained you.
      No, not to change preg_match to preg_quote, they has different task.
      it should be like this:
      [php]
      if(preg_match(“/\b”.preg_quote($b).”\b/i”, $message))
      [/php]

      for more example and usability of preg_quote, just follow my link above.

  • Roberto79

    if(!ereg(“^[a-zA-Z0-9]*$”,$username))

  • Puiu Darlea

    ROBERTO79…

    I think it goes like this:

    if(preg_match(“/^[a-zA-Z0-9]*$/i”,$username))

    Let us know if it works!

    if(!ereg($regex,$field)){
    $form->setError($fieldValue, “* Contact number invalid”);
    }
    to:
    /* Check is numeric*/
    if(!preg_match(‘/[0-9]{10}/’,$field)){

    Thnx for the info , is there any way to replace get_called_class()  to work with php 5.2 ?

      why don’t you upgrade PHP?

      Good news, I found this solution on php.net

      if(!function_exists(‘get_called_class’)) {

      function get_called_class() {

          $bt = debug_backtrace();

          $l = 0;

          do {

              $l++;

              $lines = file($bt[$l]['file']);

              $callerLine = $lines[$bt[$l]['line']-1];

              preg_match(‘/([a-zA-Z0-9_]+)::’.$bt[$l]['function'].’/',

                         $callerLine,

                         $matches);

                        

             if ($matches[1] == ‘self’) {

                     $line = $bt[$l]['line']-1;

                     while ($line > 0 && strpos($lines[$line], ‘class’) === false) {

                         $line–;

                     preg_match(‘/class[s]+(.+?)[s]+/si’, $lines[$line], $matches);

    first and foremost I want to thank who created this link, this is very helpful and how can I fix this error I encountered it says “Deprecared: Function eregi_replace()”

    here’s the code

    foreach($badword_array as $insult=>$ok){
            $cjmsg = eregi_replace(“$insult”, “$ok”, “$cjmsg”);
            }

    foreach($badword_array as $insult=>$ok){
            $name = eregi_replace(“$insult”, “$ok”, “$name”);
            }

    thanks in advance and more power.
