var_export和serialize差别比我想象还大

本文通过实验对比了PHP中var_export与serialize两种序列化方式的性能差异。结果显示,在进行1000次序列化及反序列化操作时,var_export耗时9.58秒,而serialize仅耗时3.66秒。
看到一个blog谈到var_export这个函数,于是测试了下和serialize之间的效率对比,结果比我想象还大

$funcs=get_defined_functions();

$t1=microtime(true);
for($i=0;$i<1000;++$i){
file_put_contents('test1.txt',var_export($funcs,true));
eval(file_get_contents('test1.txt').';');
}
$t2=microtime(true);
for($i=0;$i<1000;++$i){
file_put_contents('test2.txt',serialize($funcs));
unserialize(file_get_contents('test2.txt'));
}
$t3=microtime(true);
echo "var_export cost ".($t2-$t1)."\n";
echo "serialize cost ".($t3-$t2)."\n";
//var_export cost 9.58075594902
//serialize cost 3.66198205948
