hielo, you will want to leave off the U flag, it causes the ungreedy .*? to be greedy .* which is likely not what you intended:<br />

<pre><code id="code-177339">&lt;pre&gt;
&lt;?php
$str = '&lt;[edit]&gt;Item 1&lt;[/edit]&gt; Hello World &lt;[edit]&gt;Item 2&lt;[/edit]&gt; Testing &lt;[edit]&gt;Item 3&lt;[/edit]&gt;';
preg_match_all('#&lt;\[edit\]&gt;(.*?)&lt;\[/edit\]&gt;#i', $str, $matches ) ;
echo print_r($matches[1],true);
?&gt;
</code></pre>

I want everything between <br />
<br />
&lt;[edit]&gt;<br />
&nbsp; and<br />
&lt;[/edit]&gt; <br />
<br />
To go into an array. &nbsp;<br />
<br />
This should be case insensitive and must be PHP4 compatible.<br />
<br />
So in the below example, the following array should be formed:<br />
<br />
-&gt; Item 1<br />
-&gt; Item 2<br />
-&gt; Item 3<br />
<br />
&lt;[edit]&gt;Item 1&lt;[/edit]&gt; Hello World &lt;[edit]&gt;Item 2&lt;[/edit]&gt; Testing &lt;[edit]&gt;Item 3&lt;[/edit]&gt; The End<br />

Regex to place all contents of &lt;[edit]&gt;&lt;[/edit]&gt; in array

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.
