    <p>In PHP I have the following string :</p> <pre><code>$str = "AAA, BBB, (CCC,DDD), 'EEE', 'FFF,GGG', ('HHH','III'), (('JJJ','KKK'), LLL, (MMM,NNN)) , OOO"; </code></pre> <p>I need to split this string into the following parts:</p> <pre><code>AAA BBB (CCC,DDD) 'EEE' 'FFF,GGG' ('HHH','III') (('JJJ','KKK'),LLL, (MMM,NNN)) OOO </code></pre> <p>I tried several regexes, but couldn't find a solution. Any ideas?</p> <p><strong>UPDATE</strong></p> <p>I've decided using regex is not really the best solution, when dealing with malformed data, escaped quotes, etc.</p> <p>Thanks to suggestions made on here, I found a function that uses parsing, which I rewrote to suit my needs. It can handle different kind of brackets and the separator and quote are parameters as well.</p> <pre><code> function explode_brackets($str, $separator=",", $leftbracket="(", $rightbracket=")", $quote="'", $ignore_escaped_quotes=true ) { $buffer = ''; $stack = array(); $depth = 0; $betweenquotes = false; $len = strlen($str); for ($i=0; $i&lt;$len; $i++) { $previouschar = $char; $char = $str[$i]; switch ($char) { case $separator: if (!$betweenquotes) { if (!$depth) { if ($buffer !== '') { $stack[] = $buffer; $buffer = ''; } continue 2; } } break; case $quote: if ($ignore_escaped_quotes) { if ($previouschar!="\\") { $betweenquotes = !$betweenquotes; } } else { $betweenquotes = !$betweenquotes; } break; case $leftbracket: if (!$betweenquotes) { $depth++; } break; case $rightbracket: if (!$betweenquotes) { if ($depth) { $depth--; } else { $stack[] = $buffer.$char; $buffer = ''; continue 2; } } break; } $buffer .= $char; } if ($buffer !== '') { $stack[] = $buffer; } return $stack; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
