BAD IDEAS
Enclose entire class in a single try/catch blockUse sleep to wait for another task/thread to finish
Setting global vars to return multiple valuesAltering framework files
Performing DB aggregate operations in PHPKeeping connections open
Wednesday, November 2, 11
BAD IDEAS
Using self-made cyphers for encryptionClear text passwords, CC info, personal details (inc names)
Not checking for user credentials on every requestTrusting client-side input validation
Constructing sql queries by using concatenation Not using DB transactions on multiple changes
Direct access to files for download
