How to write the unique identifier in the php-JS form, please guide, thank you!
php form javascrpit layer += ‘registerx’; layer += ‘ ‘; //layer_cont layer += ‘*:<input type="hidden" name="uniqid" id="uniqid" value="” />’; layer += ‘Account*:’; layer += ‘Password*:’; layer += ‘Confirm password*:’; layer += ‘Email *: ‘; layer += ”; layer += ”; It is impossible to write like this, but I I don’t know how to write it. Is it okay to write in the PHP file of a verification form after the JS form jumps. . But did the generated uniqid change again?

java-Continue to ask for the second wave of help, that master can write this Javamd5 method into a php version, and the encryption results must be consistent, thank you!
javaphp encryption md5 Continue to seek help for the second wave, who can write a php version using the Java md5 method, and the encryption results are consistent, thank you, there is a master in the first wave I wrote one, but the encryption result is different, you can refer to it! The idea of java method description is as follows1. Convert the secret key and source string into byte arrays respectively2. Declare two 64-bit arrays, fill in the byte arrays of the key with XOR operation and supplement them respectively 54, 92 Fill up the length of 643. Obtain the MessageDigest object of the md5 digest algorithm4. Use one of the arrays and the array of the source string to update the MessageDigest digest to complete the hash calculation5. Reset the digest >6. Use another array to update the digest Use the results in 4 to start updating the digest from 0 to 16 and complete the hash calculation7. Convert the stringThe method is as followspublic String cryptMd5(String source, String key) { byte[] k_ipad = new byte[64];byte[] k_opad = new byte[64];byte[] keyb;byte[] value;try { byte[] keyb = key.getBytes(“UTF-8”);value = source.getBytes(“UTF-8”);}catch (UnsupportedEncodingException e){byte[] value;keyb = key.getBytes();value = source.getBytes();}Arrays.fill(k_ipad, keyb.length, 64,…

I am a novice in php, please help seniors, thank you~!
I just started to learn php. Because I have a little foundation before and at university, it is relatively quick to get started, but the foundation is still very weak. I am currently watching the video of teacher Han Shunping, but found that many recruitments require LAMP, so I don’t know if there are seniors who can give guidance, learning methods, etc. for the learning of linux. And where can I find more mature php cases suitable for novices, this improvement may be faster. I hope that the seniors who saw Xiaosheng’s problem will not hesitate to guide, Xiaosheng hereby thank you~ Response content: I just started to learn php.

Programmer-Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you
Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you Response content: Who can write a PHP encryption and decryption function, can customize the encryption and decryption key, thank you When I first learned VB in junior high school, I wrote an encrypted function. The general principle (process) is like this: Plaintext Xor Key 1 to get Ciphertext 1Ciphertext 1 character by character into Get ciphertext 2 in hexadecimal ciphertext 2 Xor key 2 get ciphertext 3 //Final ciphertext There are many, many ways of encryption (if you want irreversible, you can use MD5() and other functions to achieve it, or even write one yourself, haha), you can use various tricks Coincidentally, you can find ready-made encryption functions on the Internet, but I still suggest that the owner of the question think of an algorithm by himself. After all, don’t those who engage in the Web generally try not to let people know their encryption algorithms? Write your own proprietary encryption algorithm. Still need to write? Mcrpty You can use the encryption function in Disuse, the code is as follows, very easy to use //copy from here /** * $string plaintext or…

There is an array problem in PHP, I urgently ask God to solve it, kneel down and ask for a solution, I hope God will help you solve it when I get up in the morning, thank you
There is an existing array like this $arr = array( ‘0’ => array( ‘0’=>array( ‘price’ => ‘118080814c7565909’, ‘count’ => ‘100’, ‘money’ => ‘200’, ), ‘1’=>array( ‘price’ => ‘118080814c7eca590’, ‘count’ => ’10’, ‘money’ => ’27’, ), ‘2’ =>array( ‘price’ => ‘118080814c7eca5901’, ‘count’ => ’19’, ‘money’ => ‘200’, ), ), ‘1’=>array( ‘0’=>array( ‘price’ => ‘118080814c7565979’, ‘count’ => ‘100’, ‘money’ => ‘200’, ), ‘1’=>array( ‘price’ => ‘118080814c7eca888’, ‘count’ => ‘101’, ‘money’ => ’27’, ), ‘2’ =>array( ‘price’ => ‘118080814c7eca59000’, ‘count’ => ‘160’, ‘money’ => ‘200’, ), ), ‘2’=>array( ‘0’=>array( ‘price’ => ‘118080814c7565009’, ‘count’ => ‘190’, ‘money’ => ‘230’, ), ‘1’=>array( ‘price’ => ‘118080814c7eca670’, ‘count’ => ‘120’, ‘money’ => ‘217’, ), ‘2’ =>array( ‘price’ => ‘118080814c7eca5098’, ‘count’ => ‘120’, ‘money’ => ‘205’, ), ) ); What I need is to calculate the sum of the counts in the small arrays in this three-dimensional array. There are three small arrays in this three-dimensional array, and there are three other arrays in the small array. What I want is the three in the second dimension. For the sum of the array count, I foreach out and then += is to add all the counts in this three-dimensional array. I don’t need to find all the sums…
