I have a simple function:
function test(){
//some code
$X_has_val = $Y_has_val= array();
foreach ($A as $id => $row){
if(is_take($id)){
$X_has_val[$id] = $row;
}
}
foreach ($B as $id => $row){
if(is_take($id)){
$Y_has_val[$id] = $row;
}
}
//some code
}
I did this for get the equivalence
function test(){
//some code
$X_has_val = $Y_has_val= array();
foreach(array($A, $B) as $key=>$value){
foreach ($value as $id => $row){
if(is_take($id)){
$X_has_val[$id] = $row;
continue;
$Y_has_val[$id] = $row;
}
}
}
//some code
}
Looks like all you need is array_filter()
$X_has_cc = array_filter($A, 'isTake');
$Y_has_cc = array_filter($B, 'isTake');
like e.g. in
<?php
test();
function test() {
$A = array(1,2,3,4,5,6,7,8,9,10);
$B = array(99,100,101,102,103,104);
$X_has_cc = array_filter($A, 'isTake');
$Y_has_cc = array_filter($B, 'isTake');
var_dump($X_has_cc, $Y_has_cc);
}
// select "even elements"
function isTake($x) {
return 0==$x%2;
}
(and sorry, no, your approach doesn't make much sense ;-))
