i 正在从正在获取数据库值的数组中, 使用 in_ array () 函数搜索文本 。
美元值是数组值。
我怎么能忽略这个案子呢?
if(in_array($exp[$i],$value))
使用 < a href=> "http://php.net/manual/en/formation.preg-grep.php" rel = "nofollow" > preg_grep () 代替:
if( preg_grep( "/" . $exp [$i] . "/i" , $value ) )
(在 / 之后添加了 / 修饰符,使其不敏感)
然而,由于它似乎不是一个数组值,你不应该使用in_arry() ,但stristr() :
if ( stristr ($value, $exp [$i]))
(
在比较中将其转换为所有上/下大小写
if(in_array($exp[$i], strtoupper($value)))
我猜这美元[美元]也需是不可知的,所以
if(in_array(strtoupper($exp[$i]), strtoupper($value)))
