php常用方法汇总

1. PHP可阅读随机字符串

此代码将创建一个可阅读的字符串，使其更接近词典中的单词，实用且具有密码验证功能。
 

/**
 *@length - length of random string (must be a multiple of 2) 
**/
function readable_random_string($length = 6){ 
$conso=array("b","c","d","f","g","h","j","k","l", "m","n","p","r","s","t","v","w","x","y","z"); 
$vocal=array("a","e","i","o","u"); 
$password=""; srand ((double)microtime()*1000000);
 $max = $length/2; 
for($i=1; $i<=$max; $i++) 
{ $password.=$conso[rand(0,19)];
 $password.=$vocal[rand(0,4)]; 
} 
return $password; }

2.get请求封装 

    // 用于请求微信接口获取数据
    function get_by_curl($url,$post = false){
        $ch = curl_init();
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        if($post){
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
        }
        $result = curl_exec($ch);
        curl_close($ch);
        return $result;
    }
