我的這個(gè)哪里錯(cuò)了 求大佬
<?php?
echo $m1 = memory_get_usage();?
echo "<br />";
?"$var_string="123";"
echo $m2 = memory_get_usage()-$m1;?
echo "<br />";
?"$n=123;"
echo $m3 = memory_get_usage()-$m1-$m2;?
echo "<br />";
?"$f=123.00;"
echo $m4 = memory_get_usage()-$m1-$m2-$m3;?
echo "<br />";
?"$var_array= array（"123");"
echo $m5 = memory_get_usage()-$m1-$m2-$m3-$m4;?
?>

不要雙引號(hào)！！！?。。。。。。。。?br />

賦值時(shí)，不需要在最外面加雙引號(hào)，最后的數(shù)組賦值，括號(hào)用半角的。

<?php
echo $m1 = memory_get_usage();
echo "<br />";
?$var_string="123";
echo $m2 = memory_get_usage()-$m1;
echo "<br/>";
?$n=123;
echo $m3 = memory_get_usage()-$m1-$m2;
echo "<br/>";
?$f=123.00;
echo $m4 = memory_get_usage()-$m1-$m2-$m3;
echo "<br/>";
$var_array=array("123");
echo $m5 = memory_get_usage()-$m1-$m2-$m3-$m4;
?>
這樣就可以了?
