Detailed explanation of PHP debugging and performance analysis tools Xdebug and php debugging xdebug During program development, the most commonly used debugging method is to print statements using echo, print_r (), var_dump (), and printf. The execution efficiency of PHP scripts, usually the script execution time. The efficiency of Database SQL is usually the database Query time, but this does not really l

Recently, because of system problems, memory analysis tools have been reviewed (for Eclipse) Through the dump file, and then use the Memory Analysis tool on eclipse (it's easy to install online) Memory Leak lookup Idea one: Open "Details" under Leak Suspects->problem suspect N.

More than once, we all had the idea of trying to find out what was going on in the bottom of a running program. This need may be due to slow service, Java Virtual Machine (JVM) crashes, hangs, deadlocks, frequent JVM pauses, sudden or persistent high CPU usage, and even terrible memory overflows (oome). The good news is that there are a number of tools available to help you get the different parameters of the Java Virtual machine running, which will h
