Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR)
提问by Shane Malone
I have a feeling this may be a simple syntax error that I'm just not seeing, as I've had a poke around the code and cannot figure out why I'm getting the above error. The code I'm working on is a tutorial from a SAMS books, on building a calendar class. For the record, I'm running PHP 5.4.7. The below code belongs to an include that I'll show below..
我有一种感觉，这可能是一个我没有看到的简单语法错误，因为我对代码进行了一番检查，但无法弄清楚为什么会出现上述错误。我正在处理的代码是 SAMS 书籍中关于构建日历类的教程。为了记录，我正在运行 PHP 5.4.7。下面的代码属于一个包含，我将在下面展示..
function date_pulldown($name) {
$this->name = $name;
}
function setDate_global( ) {
if (!this->setDate_array($GLOBALS['$this->name'])) {
return $this->setDate_timestamp(time());
}
return true;
}
function setDate_timestamp($time) {
$this->timestamp = $time;
return true;
}
function setDate_array($inputdate) {
if (is_array($inputdate) &&
isset($inputdate["mon"]) &&
isset($inputdate["mday"]) &&
isset($inputdate["year"])) {
$this->timestamp = mktime(11, 59, 59, $inputdate["mon"], $inputdate["mday"], $inputdate["year"]);
return true;
}
return false;
}
function setYearStart($year) {
$this->yearstart = $year;
}
function setYearEnd($year) {
$this->yearend = $year;
}
function getYearStart() {
if ($this->yearstart < 0) {
$nowarray = getdate(time());
$this->yearstart = $nowarray[year]-5;
}
return $this->yearstart;
}
function getYearEnd() {
if ($this->yearend < 0) {
$nowarray = getdate(time());
$this->yearend = $nowarray[year]+5;
}
return $this->yearend;
}
function output() {
if ($this->timestamp < 0) {
$this->$setDate_global();
}
$datearray = getdate($this->timestamp);
$out = $this->day_select($this->name, $datearray);
$out .= $this->month_select($this->name, $datearray);
$out .= $this->year_select($this->name, $datearray);
return $out;
}
function day_select($fieldname, $datearray) {
$out = "<select name=\"$fieldname"."[mday]\">\n";
for ($x=1; $x<=31; $x++) {
$out .="<option value=\"$x\"".($datearray["mday"]==($x)?" SELECTED":"").">".sprintf("%02d", $x)."\n";
}
$out .="</select>\n";
return $out;
}
function month_select($fieldname, $datearray) {
$out = "<select name=\"$fieldname"."[mon]\">\n";
for ($x=1; $x<=12; $x++) {
$out .="<option value=\"".($x)."\"".($datearray["mon"]==($x)?" SELECTED":"")."> ".$this->months[$x-1]."\n";
}
$out .="</select>\n";
return $out;
}
function year_select($fieldname, $datearray) {
$out = "<select name=\"$fieldname"."[year]\">";
$start = $this->getYearStart();
$end = $this->getYearEnd();
for ($x=$start; $x<$end; $x++) {
$out .="<option value=\"$x\"".($datearray["year"]==($x)?" SELECTED":"".">$x\n";
}
$out .="</select>\n";
return $out;

You are missing a $sign:
你缺少一个$标志：
if (!this->setDate_array($GLOBALS['$this->name'])) {
should be
应该
if (!$this->setDate_array($GLOBALS['$this->name'])) {
回答by Niet the Dark Absol
if (!this->setDate
This line is missing a $before this, so thisis being treated as a constant, which doesn't exist so is treated as a string, which can't have ->after it.
此行缺少$before this，因此this被视为常量，该常量不存在，因此被视为字符串，后面不能有->。

In addition to the above mentioned if (!thisto if (!$this
除了上面提到if (!this的if (!$this
You also need to revisit this line in the function year_select:
您还需要重新访问函数中的这一行year_select：
$out .="<option value=\"$x\"".($datearray["year"]==($x)?" SELECTED":"".">$x\n";
Looks like it should be changed to:
(Note a couple changes I made were to match your formatting from other functions, there doesn't seem to be consistency)
看起来应该更改为：（
注意我所做的一些更改是为了匹配其他函数的格式，似乎没有一致性）
$out .= "<option value=\"".$x."\"".($datearray["year"]==($x)?" SELECTED":"").">".$x."\n";
