Hello,<br />
Im trying to write a PREG (php) based reg expression to replace any tokens embedded within a template to &quot;&quot;. Unfortunately, I cant seem to figure out how to properly match the tokens.<br />
<br />
The tokens are formatted as follows:<br />
<br />
[@ <i>operator</i> @]<br />
<br />
I need to be able to replace [@ * @] with just nothing.<br />
<br />
I have tried /[\[@] + [@\]]/, and various variations with no luck. I suspect my problem is that Im unsure as how to force the literal on the [ ], as well as unsure how to match anything in the middle.<br />
<br />
Thanks,<br />
Rick

PREG Reg Expression to match token

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
