PHP Function: array_trim
I was loading alot of data from .csv files, some of the data was blank and i didnt want array key=>values for it, so i created an multi dimensional array cleansing tool.
function array_trim(&$a){ foreach( $a as $k => $v ) { if ( is_array( $a[$k] ) ) array_trim( $a[$k] ); else $a[$k] = trim( $v ); if ( empty($a[$k]) ) unset( $a[$k] ); } } // Useage: array_trim( $a );
Have fun.

Nice function, thanks for sharing.
Typically l use array_walk() for a similar result.
Example:
function trim_value(&$value) {
$value = trim($value);
}
$arr = array(‘demo1 ‘, ‘demo2′, ‘ demo 3 ‘);
print_r(array_walk($arr));
