New PHP Functions<\/strong><\/p>\n\n\n\n
- New str_contains() function<\/li>
- New str_starts_with() and str_ends_with() functions<\/li>
- New fdiv() function<\/li>
- get_debug_type() function<\/li><\/ul>\n\n\n\n
<\/p>\n\n\n\n
— str_contains()<\/strong><\/p>\n\n\n\n
Helps us in determining whether the given sub-string is present inside the string.<\/p>\n\n\n\n
Example :<\/strong><\/p>\n\n\n\n
str_contains ( string $austin , string $tin ) : bool<\/code><\/pre>\n\n\n\n<\/p>\n\n\n\n
Executes a case-sensitive operations and checks whether the string austin contains the substring tin.<\/p>\n\n\n\n
<\/p>\n\n\n\n
<\/p>\n\n\n\n
— string_starts_with and str_ends_with()<\/strong><\/p>\n\n\n\n
Using this function we can easily find whether the given sub-string is at the beginning or ending of the string.<\/p>\n\n\n\n
Example:<\/strong><\/p>\n\n\n\n
str_starts_with(string $austin, string $au): bool;\n\nstr_ends_with(string $austin, string $tin): bool;<\/code><\/pre>\n\n\n\n<\/p>\n\n\n\n
These new functions can be impersonated with
strpos<\/code>,substr<\/code>,strncmp<\/code>, andsubstr_compare<\/code>. However, the new functions were favourably received due to its engine-level optimizations and their regular use cases.<\/p>\n\n\n\n<\/p>\n\n\n\n
— fdiv() <\/strong><\/p>\n\n\n\n
The new fdiv() function has similar ability as the fmod() and intdiv() functions, that allows for division by 0. Instead of getting errors, you\u2019ll get INF, -INF, or NAN, depending on the scenario.<\/p>\n\n\n\n
<\/p>\n\n\n\n
— get_debug_type()<\/strong><\/p>\n\n\n\n
The new get_debug_type function always returns the true native type of variables. It returns a return native type names, e.g., int rather than integer, double instead of float.<\/p>\n\n\n\n
