Returns
array<string>pj() ¶
pj(mixed $var): mixedJSON pretty print convenience function.
In terminals this will act similar to using json_encode() with JSON_PRETTY_PRINT directly, when not run on CLI
will also wrap <pre> tags around the output of given variable. Similar to pr().
This function returns the same variable that was passed.
Parameters
-
mixed$var Variable to print out.
Returns

list($plugin, $name) = pluginSplit($name);Parameters
-
string$name The name you want to plugin split.
-
bool$dotAppend optional Set to true if you want the plugin to have a '.' appended to it.
-

arrayLinks
pr() ¶
pr(mixed $var): mixedprint_r() convenience function.
In terminals this will act similar to using print_r() directly, when not run on CLI
