数组中的PHP搜索字符串-不区分大小写

Posted 2021-02-23

Use it similar to in_array function of php.

function in_array_str_i($key, $array){
    foreach($array as $element){
        if(strcasecmp($key, $element)==0){
            return true;
        }
    }
    return false;
}
 
$array = array(
    'string1',
    'string2',
    'StriNg3'
);
 
var_dump(in_array_str_i('string3', $array)); //bool(true). returns true
