[SOLVED] Help with string splitting

[eludlow]

I have a string that takes the following form: {1}{2}{3}

 

I need to split the string into an array based on the curly brackets - I think this is best achieved using preg_split() - would that be correct?  This would also be one of my first forays into regular expressions - would someone be able to show me the regex needed and explain how it's achieving the split, please?

 

Many thanks in advance,

Ed Ludlow

<pre>
<?php
$str = '{1}{2}{3}';
$pieces = preg_split('/[{}]/', $str, -1, PREG_SPLIT_NO_EMPTY);
print_r($pieces);
?>
</pre>

 

preg_* functions use delimiters, thus the /.../. [...] is a character class which matches one character out of its pool, in this case { or }.

 

You can find more details in my signature links.

You can do this:

<?php
$str = '{1}{2}{3}';
$arr = explode('}{',ltrim(rtrim($str,'}'),'{'));
echo '<pre>' . print_r($arr,true) . '</pre>';
?>

No regular expressions needed.
