关于perl内存使用过大,导致crash的问题.

fq43

'foreach' need an array object, then enumerate each line in the array.

I think system memory allocation functiong crash because your program will try to allocat a large block memory to read all data from your source file when you call 'foreach (<DATA>)',

Just read one line from the file when call 'while(<DATA>)' in the loop.

cdtits

貌似原来是程序问题

不过foreach和while这种细微的用法差别确实很难把握
perl有那么多种循环的写法，要有个最佳实践就好了。
学python时也是，不同的用法可能性能差别很大。
印象里面python是提倡用迭代的。
