// PREG_FIND_NEGATE      - return files that don't match the pattern
// PREG_FIND_RETURNASSOC - Instead of just returning a plain array of matches,

// You can also request to have the results sorted based on various criteria

// sorting on values stored in the constructed associative array
// PREG_FIND_SORTBASENAME - Sort the results in alphabetical order on filename
// PREG_FIND_SORTMODIFIED - Sort the results in last modified timestamp order
// PREG_FIND_SORTFILESIZE  - Sort the results based on filesize
// PREG_FILE_SORTDISKUSAGE - Sort based on the amount of disk space taken
// to use more than one simply seperate them with a | character

// if args contains PREG_FIND_RECURSIVE then do a recursive search

<h2><strong><a name="intro"></a><span style="font-family: helvetica; font-size: small;"><em>Om ... te</em> + infinitive to express purpose </span></strong></h2>
<div class="highlight1lt"><span style="font-family: helvetica; font-size: small;">The combination <em>om ... te</em> + infinitive expresses purpose (as in English &lsquo;in order to') and is used widely. It is not a difficult construction and you will not find it complicated to understand or use. The phrase begins with <em>om</em> and ends with <em>te + </em> infinitive.<span style="color: fuchsia;"> </span> </span> <br /><br />
<p class="MsoNormal style16 style21">Some examples:</p>
<dl class="style14"> <dt><em>Sommige mensen gaan naar de kroeg <span style="color: red;">om</span> vrienden <span style="color: red;">te ontmoeten</span>. </em></dt> <dt>Some people go the bar (in order) to meet friends.</dt><dt><br /></dt> </dl> <dl class="style14"> <dt><em>Alan belt Simone <span style="color: red;">om</span> een afspraak <span style="color: red;">te maken</span>. </em></dt> <dt>Alan rings Simone (in order) to make an appointment.</dt><dt><br /></dt> </dl> <dl> <dt class="style14"><em>Karin en Simone gaan naar de slager <span style="color: red;">om</span> varkenslappen <span style="color: red;">te kopen</span>. </em></dt> <dt class="style14">Karin and Simone go to the butcher (in order) to buy pork steaks.</dt>

<div class="highlight1lt"><span style="font-family: helvetica; font-size: small;">There is another type of construction in Dutch where <em>om &hellip; te</em> + infinitive is used. Here, however, the word <em>om</em> is not necessary and is often omitted. Here, the construction does NOT express purpose. It is only possible with specific verbs (e.g. <em>besluiten</em>).
