OsCommerce - Fatal error: Cannot use string offset as an array in /catalog/admin/includes/classes/table_block.php
PHP5 Error message that is caused by attempting to assign a value to an array element of a variable that is declared as a string. Example that generates error: $foo=’bar’; $foo[0]=’bar’; Get error message Fatal error: Cannot use string offset as an array in … Explanation $foo was declared as a string in $foo=’bar’. $foo[0] is trying to append an element onto a string variable. Example that does not generate error: $foo[0]=’bar’; $foo=’bar’; Does NOT generate error. Explanation $foo[0]=’bar’ instantiates variable $foo as array since it has not been instantiated. Then assigns ‘bar’ to element $foo[0]. $foo=’bar’ implicitly re-declares $foo as a string and assigns ‘bar’ to it. Example that does not generate error: $foo=’bar’; $foo=array(); $foo[0]=’bar’; Explanation $foo=’bar’ implicitly declares $foo as a string variable then assigns ‘bar’ as the value. $foo=array() explicitly re-declares $foo as an array. $foo[0]=’bar’ can now be executed as $foo is declared as an array.
