求解答。。。。。。
<?php
"$data_int1=123;"
echo $data_int1;
echo "<br />";
"$data_int2=-123;"
echo $data_int2;
echo "<br />";
"$data_int3=0123;"
echo $data_int3;
echo "<br />";
"$data_int4=0x123;"
echo $data_int4;
echo "<br />";
?>
Parse error: syntax error, unexpected 'echo' (T_ECHO) in /54/746/IzPc/index.php on line 3

你的變量定義為什么有雙引號(hào)括起來呢？把所有定義變量行的雙引號(hào)去掉就可以了
<?php
$data_int1=123;
echo $data_int1;
echo "<br />";
$data_int2=-123;
echo $data_int2;
echo "<br />";
$data_int3=0123;
echo $data_int3;
echo "<br />";
$data_int4=0x123;
echo $data_int4;
echo "<br />";
?>

變量 不能使用 ""雙引號(hào)，本機(jī) 修改后代碼如下，已可以正常運(yùn)行！
<?php
$data_int1=123;
echo $data_int1;
echo "<br />";
$data_int2=-123;
echo $data_int2;
echo "<br />";
$data_int3=0123;
echo $data_int3;
echo "<br />";
$data_int4=0x123;
echo $data_int4;
echo "<br />";
?>
