The PHP variable is a C-language structure,

Can you explain it in detail? I don't know much.

The string in PHP is implemented as a array of bytes and an integer indicating the length of the buffer.

PHP is written in C + +, it should also use "\ n"

The variable structure of PHP is as follows:

typedef struct _ZVAL_STRUCT Zval;typedef Union _zvalue_value {    long lval;                 /* Long value */    double dval;               /* Double value */    struct {/                   * String type */        char *val;        int len;    } STR;    HashTable *ht;             /* Hash Table value */    zend_object_value obj;} zvalue_value; struct _zval_struct {/    * Variable information */    zvalue_value value;        /* Value */    zend_uint refcount__gc;    Zend_uchar type;           /* Active type */    Zend_uchar is_ref__gc;};

And then you get the idea.

PHP variables have a save string length, so you don't need to use symbols to judge

Thank you,!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.
