I'm getting
illegal offset type
error for every iteration of this code. Here's the code :
$s = array(); for($i = 0; $i < 20; $i++){ $source = $xml->entry[$i]->source; $s[$source] += 1; } print_r($s)
Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key.
Example:
$x = new stdClass(); $arr = array(); echo $arr[$x]; //illegal offset type
Your $xml
array contains an object or array at $xml->entry[$i]->source
for some value of $i
, and when you try to use that as an index key for $s
, you get that warning. You'll have to make sure $xml
contains what you want it to and that you're accessing it correctly.
Use trim($source)
before $s[$source]
.
