推薦：40個優(yōu)化php代碼的技巧
40條優(yōu)化php代碼的小實(shí)例 1.如果一個方法能被靜態(tài)，那就聲明他為靜態(tài)的，速度可提高1/4; 2.echo的效率高于print,因?yàn)閑cho沒有返回值，print返回一個整型; 3.在循環(huán)之前設(shè)置循環(huán)的最大次數(shù)，而非在在循環(huán)中; 4.銷毀變量去釋放內(nèi)存，特別是大的數(shù)組; 5.避免使

這是在看太平洋網(wǎng)的評論時看到的，太平洋網(wǎng)是用jsp做為后臺語言，用來產(chǎn)生xml文件．然后在把數(shù)據(jù)綁定到html上的．我就用php也做了一個以下是源文件．
