Description:
------------
The recent changes in 7.2 must have introduced a major regression in foreach() looping and variable
assignment.
Test script:
---------------
// BROKEN NOW IN PHP7.2
foreach ($productAttributeKeys as $type) {
$isDefined = $this->attributeTransferCollection->has($type);
$shouldBeTextArea = mb_strlen($value) > 255;
if ($isDefined) {
continue;
}
if ($shouldBeTextArea) {
$inputType = self::TEXT_AREA_INPUT_TYPE;
}
...
}
// FIXED WITH: Moving continue statement up
foreach ($productAttributeKeys as $type) {
$isDefined = $this->attributeTransferCollection->has($type);
if ($isDefined) {
continue;
}
$shouldBeTextArea = (mb_strlen($value) > 255);
if ($shouldBeTextArea === true) {
$inputType = self::TEXT_AREA_INPUT_TYPE;
}
...
}
Expected result:
----------------
No notice/error on the most basic
$shouldBeTextArea = mb_strlen($value) > 255;
if ($isDefined) {
continue;
}
if ($shouldBeTextArea) {
$inputType = self::TEXT_AREA_INPUT_TYPE;
}
Actual result:
--------------
When using continue, variables that must be assigned and fine are suddenly now throwing
"Undefined variable: shouldBeTextArea" - this worked in all PHP versions until 7.1 incl.
