I am trying loop over an array with a foreach().
When I tested the code below,
$aa = array("'a1','a2'","'b1','b2'","'c1','c2'");
foreach($aa as $bb){
$cc = array($bb);//var_dump($cc); (1) { [0]=> string(9) "'a1','a2'" }...
foreach($cc as $dd){
echo $dd.'<br />';
break;
}
}
It will output:
'a1','a2'
'b1','b2'
'c1','c2'
But I want a1,b1,c1
.
Wrong with $cc = array($bb)
...
What is the problem?
You have one level array, not two. Elements are just strings for php, not arrays. That's why your code doesn't work.
Replace your $cc = array($bb)
string with smth like this:
$cc = explode(',', $bb);
foreach($cc as $dd){
echo trim($dd, "'").'<br />';
break;
}
