Use php to generate pictures, but the output is garbled characters, how to solve it
Use php to generate pictures, output is garbled characters, how to solve it? <?php $a=imagecreatetruecolor(300,200); imagepng($a); imagedestroy($a); ?> Use php to generate a picture The output is garbled characters, use echo The output content is not garbled characters ——Solution——————- For PHP , garbled characters will appear when outputting pictures. There are many reasons for garbled characters, the most common one is that there are other content output before outputting the picture, resulting in whether the picture can not be output normally . The reason for this phenomenon is this function: header(“Content-type:image/jpeg”); Note: the role of the header function It is to tell the browser how to output the following content , for example: header(“Content-type: html/text”); means to tell the browser that the content to be followed should be output as html text format output; header(“Content-type:application/stream”); means to tell the browser that the following content should be output in the form of byte stream ; header(“Content-type:image/jpeg”); means to tell the browser that the following content should be output as a picture .

But now I feel that I still can’t do anything, the basic knowledge is not solid, so I want to consolidate, I want to try to write some functional modules, but I can’t start, is it because I fooled something, I found some source code, but I don’t know How to start learning, and the source code is too long, it seems particularly difficult to persist, how should I do it now? Experienced seniors give advice to the younger brother. ——Solution——————-Since you know that it is extremely difficult for you to persevere, then you also know your weaknesses… The more difficult things are, the more courage you need to overcome them. ——Solution ———————To Saying “hold on” is bullshit.

PHPADODB database operation, how to solve it
PHP ADODB database operationRecently, I am working on a project. The client is MSSQL, but my resources here are only MYSQL, so I choose ADODB to operate. After developing the MYSQL version without problems, the code was packaged to the customer (the customer did not provide all resources due to security issues). The test results were resolved through emails, and it was found that Execute did not execute additions, deletions, and modifications. Only post key codes. Because time is urgent, I can’t go to the other party’s server to test, and I can’t access the page. Anyone who knows can let me know? $db = ADONewConnection(“”mssqlnative””);$sql9 = “UPDATE table SET table_type=1 WHERE user_id=1”; >$db->Execute($sql9); ——Solution idea———– ———– $db = ADONewConnection(“”mssqlnative””);//Double quotes in Chinese state ——Solution idea——————- —Don’t be kidding! You have to load the extension of the corresponding database before you can use the adodb class library The adodb class library also uses an error handling mechanism, don’t you read the error information it provides?

When setting role permissions in the background of PHPCMS, a 500 exception suddenly appears, how to solve it
When setting role permissions in the PHPCMS background, a 500 error suddenly appears, how to solve it? When setting role permissions in the PHPcms background, a 500 error occurs when clicking the default site, as shown in the figure above. Under normal circumstances, it is shown in the figure below. It was working fine, but suddenly it doesn’t work for some reason, please answer? ? What’s going on here? — —Solution ideas ———————-There is a serious grammatical error in that request, go in and check the breakpoint ——Solution idea———————-Look mistake. ——Solved Idea ———————-500 is the server refuses to respond, usually there is an error in the php program. If you don’t give an error message, the gods can’t help you. If the local is normal and the server is not, then it only means that the program has no syntax errors, but it does not mean that there is no logic ErrorsSuch as division by 0, illegal variable value, field not found, etc. . . . In addition, it is also related to php version and configuration——Solution idea—————- ——Like folder read and write permissions, path, php version, php environment settings, and different server software may cause errors
