Php internals

• [RFC] Saner string to number comparisons - In his recent RFC, Nikita Popov proposes to change the behavior == and make loose comparisons less error-prone. In particular, the comparison of numbers is proposed to be used only if the compared string is in fact a numeric one. Otherwise, the number is converted to a string, and a string comparison is performed.

  

  This sentence entails a change in the behavior of comparison operators <=> , == != , > , >= , < , And <= , switch constructions, functions of the in_array() , sort() and other types.
  
  In response, ideas of varying degrees of radicalism came: from the introduction of a special flag declare('strict_comparison=1'); which would turn everything == into === , until the proposal to cancel == in general .
  ')
  In the meantime, in 7.4, Warning is likely to be thrown if the result of the comparison differs from that expected in PHP 8.
• [RFC] Permit trailing whitespace in numeric strings - Another proposal designed to improve consistency, but by weakening. It is proposed to allow whitespace characters at the end of numeric lines, that is, so that "123 " == " 123" and all other operations worked, as well as for lines with leading spaces.
• [RFC] Consistent type errors for internal functions - The clause is accepted and, in PHP 8, the built-in functions will throw a TypeError if the parameters of the wrong type are passed and accordingly will not return null.
• [RFC] Weak References - Suggestion for implementing weak links is accepted.
• [RFC] Locked Classes — It is proposed to introduce a new locked keyword for classes. Such classes will be closed for dynamic use of properties, that is, you cannot access undeclared properties:

   locked class TestClass { public $definedProp; } $t = new testClass(); $t->definedProp = "OK"; echo $t->definedProp; unset($t->definedProp); echo $t->nonExistentProp; // Error $t->nonExistentProp = "Not OK"; // Error unset($t->definedProp); // Error
