PHP array Delete empty array program _php tutorial

There are many ways to remove an array of empty elements, and I'm going to introduce two classic methods today, one using the Array_filter function and the other using the function to call the custom function.

The code is as follows	Copy Code
$str 1_array=array (' A network of tutorials ', ' ', ' http://www.bKjia.c0m ', ' ', ' 1654 ', '); $str 1_array=array_filter ($str 1_array); Print_r ($str 1_array); ?> Results Array ( [0] = + A-Poly tutorial net [2] = http://www.bKjia.c0m [4] = 1654 )

Instance

The code is as follows

Copy Code

$fangId = Postget (' Houseid '); Get Address bar value $tempArray = Array_filter (Explode (' _ ', $fangId), "filter"); Break into an array with __ and delete an empty array if (Is_array ($tempArray) &&!empty ($tempArray))//Determine if the array has values { Print_r ($tempArray); Test output } Else { MessAge (' Please choose to compare to the real estate ', ' list.php '); } function filter ($var) handler { if ($var = = ") { return false; } return true; }

Test method:/compare.php?houseid=2306__2307__2303__2308
