[php-src] Issue #19118: Too big `string` to `int` cast results nonsense

Issue: https://github.com/php/php-src/issues/19118 Author: kkmuffme ### Description The following code: ```php <?php if ( (string) PHP_INT_MAX === '9223372036854775808' ) { echo "string identical" . PHP_EOL; } if ( PHP_INT_MAX === (int) '9223372036854775808' ) { echo "int identical" . PHP_EOL; } ``` Resulted in this output: ``` int identical ``` But I expected this output instead: ``` Deprecated: Conversion from string '9223372036854775808' to int loses precision ``` A very similar error already exists when converting float to int implicitly e.g. $a[ PHP_INT_MAX + 1 ] = ''; See also https://github.com/php/php-src/issues/17081 which reports that for float/int casts ### PHP Version ```plain PHP 8.4.8 ``` ### Operating System _No response_
