To split Pascal/CamelCase into Title Case (for example, converting descriptive class names for use in human-readable frontends), you can use the below function: <?php function expandCamelCase($source) { return preg_replace('/(?<!^)([A-Z][a-z]|(?<=[a-z])[^a-z]|(?<=[A-Z])[0-9_])/', ' $1', $source); } ?> Before: ExpandCamelCaseAPIDescriptorPHP5_3_4Version3_21Beta After: Expand Camel Case API Descriptor PHP 5_3_4 Version 3_21 Beta ---- Server IP: 69.147.83.199 Probable Submitter: 121.98.82.15 ---- Manual Page -- http://php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/111695 Del: integrated -- https://master.php.net/note/delete/111695/integrated Del: useless -- https://master.php.net/note/delete/111695/useless Del: bad code -- https://master.php.net/note/delete/111695/bad+code Del: spam -- https://master.php.net/note/delete/111695/spam Del: non-english -- https://master.php.net/note/delete/111695/non-english Del: in docs -- https://master.php.net/note/delete/111695/in+docs Del: other reasons-- https://master.php.net/note/delete/111695 Reject -- https://master.php.net/note/reject/111695 Search -- https://master.php.net/manage/user-notes.php
