We have built a recruitment website before, so we need to prevent others from collecting our customers’ mobile phone numbers and email addresses, so we will use PHP to directly generate a picture from the mobile phone numbers and email addresses read from the database. , in the past, the collection could only be pictures and could not be recognized. Let me introduce two examples to you.

PHP string processing - save mobile phone number as picture

The code is as follows

Copy code

代码如下

复制代码

////电话号码转变成图片
//$str 要显示的字串，$rand是否启用扰码
function str_to_image($str,$w=130,$h=25,$rand=true)
{
//生成11位的数字图片

//定义图片宽高
$nwidth=$w;
$nheight=$h;
//srand((double)microtime()*1000000); //取得目前时间的百万分之一秒值，以执行时的百万分之一秒当乱数种子
$randval=$str; //11位数
$im=@imagecreate($nwidth,$nheight) or die("Can't initialize new GD image stream"); //建立图象
//图片色彩设置
$background_color=imagecolorallocate($im,255,255,255); //匹配颜色
$text_color=imagecolorallocate($im,23,14,91);
//绘制图片边框
imagefilledrectangle($im,0,0,$nwidth-1,$nheight-1,$background); //矩形区域着色
imagerectangle($im,0,0,$nwidth-1,$nheight-1,$background_color); //绘制矩形
imagestring($im,8,10,4,$randval,$text_color); //绘制横式字串
