PHP 7.2 Function create_function() is deprecated

Viewed 94 times

I have used create_function in my application below.

$callbacks[$delimiter] = create_function('$matches', "return '$delimiter' . strtolower($matches[1]);");

But for PHP 7.2.0, the create_function() is deprecated.

Any idea, how to fix my codes above on PHP 7.2.0.

Thanks for your help,

You should be able to use an Anonymous Function (aka Closure) with a call to the parent scoped $delimiter variable, like so:

$callbacks[$delimiter] = function($matches) use ($delimiter) {
    return $delimiter . strtolower($matches[1]);
};

Switch to preg_replace^Docs and update the expression to use preg syntax (PCRE) instead of ereg syntax (POSIX) where there are differences^Docs (just as it says to do in the manual for ereg_replace^Docs).

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)

Options:
  ...
  -r, --register-only
        do not remove files, only register the packages as not installed
  ...

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

You must use preg_match instead of ereg because the last one is deprecated.

Replacing it is not a big deal:

ereg( "[][{}()*+?.\^$|]", $_REQUEST['name'] )

will become:

preg_match( "/[][{}()*+?.\^$|]/", $_REQUEST['name'] )

p.s. I had to modify more than one hundred files while I was porting my old project to PHP 5.3 to avoid manually modifying I've used following script to do it for me:

function replaceEregWithPregMatch($path) {
    $content = file_get_contents($path);
    $content = preg_replace('/ereg(("|')(.+)("|'),/',
                            "preg_match('/$2/',",
                            $content);
    file_put_contents($path, $content);
}

I hope it helps.

Never used any of those, but they look interesting..

Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
