Hello Everyone
Just wanted to point smth interesting i found out.
$id = '3047';
$array = array (
'3047' => '',
'3049' => '',
'3074' => ''
);
As you can see, all key's are numers but in string form.
foreach ($przedmioty as $key => $val){
echo var_dump ($id);
echo var_dump ($key);
die();
}
Will output
string(4) "3066"
int(3047)
Foreach tries to convert key to int, if it succedes $key is reurned as int. (haven't tested
double)
Thus, you can't compare string with it with === operator. Tried to compare it with get to
exclude which key shouln't be generated
