Note Submitter: Ray.Paseur often uses Gmail ---- Array-to-String conversion by assignment or by using an array in a string context gives a string of data that contains only the word, 'Array' and this data substitution often occurs silently. This happens because the standard PHP installation suppresses Notice-level messages, and the array-to-string conversion, even though it causes data loss, is only considered a Notice condition. Here is how to discern what PHP is doing. http://php.net/manual/en/language.types.array.php http://php.net/manual/en/language.types.string.php#language.types.string.casting <?php // demo/array_to_string.php /** * Starting with the default standard error-level of E_ALL ~ E_NOTICE * OUTPUTS: * Array */ $xyz = array('X', 'Y', 'Z'); echo $xyz; /** * Setting the error-level of E_ALL causes Notice messages to appear * OUTPUTS: * Notice: Array to string conversion in /path/to/demo/array_to_string.php on line XXX * Array */ error_reporting(E_ALL); $xyz = array('X', 'Y', 'Z'); echo $xyz;
