PHP mobile phone number generation Picture Instance Program _php Tutorial

Previously did a recruitment site so we need to let not collect our customer's mobile phone number and email address, so we will use PHP to realize from the database read the mobile phone number and email address directly generated a picture, so that the past can only be a picture and can not be recognized, below I would like to introduce you to two examples.

PHP string processing-Mobile phone number to live picture

The code is as follows

Copy Code

The phone number turns into a picture $str the string to display, $rand whether to enable the scrambling code function Str_to_image ($str, $w =130, $h =25, $rand =true) { Generate a 11-bit digital picture Header ("Content-type:image/png"); Tell the browser that the following data is a picture, not a text display Define Picture Width height $nwidth = $w; $nheight = $h; Srand (Double) microtime () *1000000); Gets the current time of one out of 10,000 seconds value to execute when the random number of one out of 10,000 seconds seeds $randval = $str; 11-digit Number $im = @imagecreate ($nwidth, $nheight) or Die ("Can ' t initialize new GD image stream"); Creating images Picture color settings $background _color=imagecolorallocate ($im, 255,255,255); Match color $text _color=imagecolorallocate ($im, 23,14,91); Draw a picture border Imagefilledrectangle ($im, 0,0, $nwidth-1, $nheight-1, $background); Rectangle Area Coloring Imagerectangle ($im, 0,0, $nwidth-1, $nheight-1, $background _color); Draw a rectangle Imagestring ($im, 8,10,4, $randval, $text _color); Draw a cross-string if ($rand) { Adding interference factors for ($i =0; $i <260; $i + +) { $randcolor =imagecolorallocate ($im, Rand (0,255), Rand (0,255), Rand (0,255)); Imagesetpixel ($im, rand ()% ($nwidth-5), Rand ()% ($nheight +5), $randcolor); Point } } Imagestring ($im, 3,5,5, "A simple Text String", $text _color); Imageinterlace ($im, 1); Imagepng ($im); Creating PNG patterns Imagedestroy ($im); End chart Type } $str = ' 13087263453 '; Echo str_to_image ($str, $w =130, $h =25, $rand =true)

Example 2

The code is as follows

Copy Code

$id =$_get[id]; Include ("admin/config.php"); $sql = "SELECT * from user where id= $id"; $data =mysql_fetch_array (mysql_query ($sql)); $p =sbc_dbc ($data [phone],1); function Get_str ($str, $strlen =16) { $str =stripslashes ($STR); for ($i =0; $i < $strlen; $i + +) if (Ord (substr ($str, $i, 1)) >0xa0) $j + +; if ($j%2!=0) $strlen + +; $tmp _str=substr ($str, 0, $strlen); return $tmp _str; } if ($p <> ") { Generate a 5-bit digital picture Header ("Content-type:image/png"); Tell the browser that the following data is a picture, not a text display Define Picture Width height $nwidth = 120; $nheight = 25; $im = @imagecreate ($nwidth, $nheight) or Die ("Can ' t initialize new GD image stream"); Creating images Picture color settings $background _color=imagecolorallocate ($im, 255,255,255); Match color $text _color=imagecolorallocate ($im, 23,14,91); Draw a picture border Imagefilledrectangle ($im, 0,0, $nwidth-1, $nheight-1, $background); Rectangle Area Coloring Imagerectangle ($im, 0,0, $nwidth-1, $nheight-1, $background _color); Draw a rectangle Srand (Double) microtime () *1000000); Gets the current time of one out of 10,000 seconds value to execute when the random number of one out of 10,000 seconds seeds $randval =rand (); $randval = $p; 5-digit number Imagestring ($im, 8,10,2, $randval, $text _color); Draw a cross-string Adding interference factors for ($i =0; $i <478; $i + +) //{ $randcolor =imagecolorallocate ($im, Rand (0,255), Rand (0,255), Rand (0,255)); Imagesetpixel ($im, Rand ()%100,rand ()%30, $randcolor); Point //} Imagestring ($im, 3,5,5, "A simple Text String", $text _color); Imageinterlace ($im, 1); Imagepng ($im); Creating PNG patterns Imagedestroy ($im); End chart Type }else{ echo "The merchant did not enter a phone number"; } ?>
