To cast to boolean, use the (bool) statement:Example $a = 5; // Integer $b = 5.34; // Float $c = 0; // Integer $d = -1; // Integer $e = 0.1; // Float $f = "hello"; // String $g = ""; // String $h = true; // Boolean $i = NULL; // NULL $a = (bool)...
INF-->"INF"// float 对于 int 类型来说太大了,回退为 string true-->1// int 兼容 bool [] -->TypeError// int 或 string 不兼容 array // int|float|bool "45"-->45// int 数字 string "45.0"-->45.0// float 数字 string "45X"-->true// 不是 numeric string,回退为 bool ""-->fals...
This also includes the (int) cast operation, and the following functions: intval() (where the base is 10), settype(), decbin(), decoct(), and dechex(). 5.mt_rand 算法修复 mt_rand() will now default to using the fixed version of the Mersenne Twister algorithm. If deterministic outpu...
