53008439Today, the project manager asked me a question, asked me here are 2000 URLs to check whether it can open, in fact, I was refused, I know because to write code, just learned a little python, a think, Python processing easy, chose Python, began to think good:1. First 2000 URLs. Can be placed within a txt text2. Use Python to put the URL within the content into the array in one line3. Open a simulated browser to access it.4. If normal access is output normal, error output errorDirect simple

The following is a simple instance code that checks whether a file exists: Copy Code code as follows: $filename = '/path/to/foo.txt '; if (file_exists ($filename)) { echo "The file $filename exists"; } else { echo "The file $filename does not exist"; } ?> If the file exists, the result of executing the PHP file is: The file C:blablaphphello.txt exists. If the file does not exist, the result of executing the PHP file

When developing Android applications, it involves network access, often requiring network state checks to provide users with the necessary reminders. It is generally possible to complete the work by Connectivitymanager.Connectivitymanager has four main tasks:1, monitor the status of mobile phone network (including Gprs,wifi, UMTS, etc.)2, mobile phone status change, send broadcast3, when a network connection fails to failover4. Provide applications wi

The example in this article describes the way JavaScript checks whether a substring is in a string. Share to everyone for your reference, specific as follows: var strnew=" Hello Raghu How are U "//checking existence in entire string if (strnew.indexof ("Raghu")!=-1) {alert ("Exists");}/* Checking existence at the ' end of ' of string for example, variable result1 in the F ollowing example is assigned the value of true because the word "Ishmae

Array_key_exists () The PHP array_key_exists () function checks whether a given key name or index exists in an array, returns TRUE if it exists, or returns FALSE. Grammar: the bool Array_key_exists (mixed key, array search) parameter key is the given key name or index, and can be any value that can be indexed as an array. The array_key_exists () function can also be used for objects. Example: The example output is as follows: The key na

The synchronization of databases across computer rooms will inevitablyThere is a network jitter, an exception that is caused by the slave Io,slave SQL thread shutdown situation.2. Solution to the thinking1) Write a script to monitor the slave status regularly2) Use Shell to write3) Use crontab per minute to check, judge, and then execute the start slave according to judgmen
