How can I use preg_match
to see if special characters [^'£$%^&*()}{@:'#~?><>,;@|-=-_+-¬`]
exist in a string?
Answers
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).
$ts = array("/[À-Å]/","/Æ/","/Ç/","/[È-Ë]/","/[Ì-Ï]/","/Ð/","/Ñ/","/[Ò-ÖØ]/","/×/","/[Ù-Ü]/","/[Ý-ß]/","/[à-å]/","/æ/","/ç/","/[è-ë]/","/[ì-ï]/","/ð/","/ñ/","/[ò-öø]/","/÷/","/[ù-ü]/","/[ý-ÿ]/");
$tn = array("A","AE","C","E","I","D","N","O","X","U","Y","a","ae","c","e","i","d","n","o","x","u","y");
preg_replace($ts,$tn, $p);
Make an array of the special characters and an array of the regular character and use preg_replace() on the string like above.
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 ..
I think the best way would be to create a keyboard layout from scratch, using the Microsoft Keyboard Layout Creator.
You can load an existing layout and customize it however you want, or create a brand new one, including combinations with modifier keys.
[W]+
will match any non-word character.but to match only the characters from the question, use this:
