語法錯誤，意外 '{' PHP

Question

我的PHP代碼提供了以下錯誤：

syntax error, unexpected '{' on line 8 

PHP代碼：

$data = '<?php 
# 1 = ON; 0 = OFF. 
$str = '{       //line 8 
"name": "10.000000,106.000000", 
    "Status": { 
    "code": 200, 
    "request": "geocode" 
}, 
    "Apps": [ { 
    "App1": 1, 
    "App2": 0,  
    "App3": 1, 
    "App4": 0, 
    "App5": 0, 
    "App6": 0 
} ] 
}'; 
    echo $str; 
?>'; 

我到PHP新手。任何人都可以幫我找到我錯在哪裏嗎？謝謝。

Answer 1

這是因爲在這裏第二'：

 +-- open string constant 
     V 
$data = '<?php 
    # 1 = ON; 0 = OFF. 
    $str = '{ 
     ^
      +-- close string constant 

是終止字符串常量。你可能想逃避它（另一位剛剛最終echo前），如：

$data = '<?php 
    # 1 = ON; 0 = OFF. 
    $str = \'{ 
     blah, blah, blah 
    }\'; 
    echo $str; 
?>'; 

Answer 2

你的字符串得到了由{字符前右單引號（單引號）終止。使用\'退出'字符。

$data = '<?php 
# 1 = ON; 0 = OFF. 
$str = \'{       //line 8 
"name": "10.000000,106.000000", 
    "Status": { 
    "code": 200, 
    "request": "geocode" 
}, 
    "Apps": [ { 
    "App1": 1, 
    "App2": 0,  
    "App3": 1, 
    "App4": 0, 
    "App5": 0, 
    "App6": 0 
} ] 
}\'; 
    echo $str; 
?>';
