如果你在数组中做同样的事情,则仍然会持有该对象的引用,从而导致内存泄露。 我们编写一段示例代码如下: 代码语言:javascript 复制 <?phpdeclare(strict_types=1);classFooBar{publicWeakMap $cache;publicfunction__construct(){$this->cache=newWeakMap();}publicfunctiongetSomethingWithCaching(object $obj){return...
<?php function change($str){ return str_replace("xx","x",$str); } $arr['name'] = $_GET['name']; $arr['age'] = $_GET['age']; echo "反序列化字符串:"; var_dump(serialize($arr)); echo ""; echo "过滤后:"; $old = change(serialize($arr)); var_dump($old); echo "...
strtr(string,array) 6.strtr符合意愿的使用方法 <?php $table_change = array('you'=>'her sister'); echo strtr("I Love you",$table_change); ?> 结果为: I Love her sister 7.小技巧:你想到替换什么你就往数组加什么 比如: <?php
#[ReturnTypeWillChange]对于需要支持多个 PHP 版本的库,当前支持使用属性来避免这种情况。传递null给内部函数的不可为空参数已被弃用。这以前是允许的,但与用户创建的函数的类型提示强制不一致。隐式转换 from inttofloat已被弃用 - 这会影响诸如 的情况$array[10.1],其中尾数将丢失,因为数组必须具有整数键。...
