PHP字符串替换str_replace()函数四种用法
参数 $search,要替换的字符串，或数组
参数 $replace,被用来替换的字符串或数组
参数 $subject,被查询的字符串或数组
参数 $count，可选，如果被指定，将为设置为替换的次数
返回值：该函数返回替换后的数组或者字符串(新生成的)
实例一：字符串替换字符串
$str1 = str_replace("red","black","red green yellow pink purple");
echo $str1.""; //输出结果为black green yellow pink purple实例二：字符串替换数组键值
$arr = array("blue","red","green","yellow");
$str1 = str_replace("red","pink",$arr,$i);
print_r($str1);实例三：数组替换数组，映射替换
$arr1 = array("banana","orange");
$arr2 = array("pitaya","tomato");
$con_arr = array("apple","orange","banana","grape");
$con_rep = str_replace($arr1,$arr2,$con_arr,$count);
print_r($con_rep);实例四：如$search为数组，$replace为字符串时
$search = array("banana","grape");
$replace = "tomato";
$arr = array("banana","apple","orange","grape");
$new_arr = str_replace($search,$replace,$arr,$count);
print_r($new_arr);
