print_r($array, false); “` 这将输出类似于var_dump函数的结果,包括键名和键值。 4. 在嵌套数组和对象的情况下,print_r函数可能会因为缺乏手动缩进而导致输出不易阅读。如果您希望手动缩进并进行格式化,您可以使用递归函数来处理嵌套结构,如下所示: “`php function print_formatted($array, $indent = 0) {...
echo $formatted; 5. `print_r`和`var_dump`: 这两个函数主要用于调试,尤其是处理数组和对象时。`print_r`输出数组和对象的可读性较强,但对布尔值的表示可能不够直观。例如: php $array = array('one', 'two', 'three'); print_r($array); 而`var_dump`提供了更详细的输出,包括数据类型、长度等信...
