[TYPO3-core] RFC: #15440: isFirstPartOfStr doesn't work with non-strings

[Steffen Kamper]

Hi,

this is an SVN patch request

Type: bugfix

Branches: 4_4, trunk

BT: http://bugs.typo3.org/view.php?id=15440

These should return TRUE:

t3lib_div::isFirstPartOfStr('24', 24)
t3lib_div::isFirstPartOfStr('24 Bier bitte', 24)


These should return FALSE:

t3lib_div::isFirstPartOfStr(NULL, 0)
t3lib_div::isFirstPartOfStr('', 0)

Solution: cast input values to string

Attached patch + test solves it.

vg Steffen
