PHP Parse error: syntax error, unexpected T_VARIABLE solution

When writing PHP code, sometimes you will encounter the following message: PHP Parse error: syntax error, unexpected T_VARIABLE. This is because there are grammatical errors in the code, such as irregular naming of variables, spelling errors, use of inappropriate symbols, etc., which ultimately lead to parsing errors. Once this prompt message appears, there will be problems when running the program, so it needs to be solved in time.

The following are several common situations of PHP Parse error: syntax error, unexpected T_VARIABLE and corresponding solutions.

1. Variable name error

When the variable name is not standardized or spelled incorrectly, an error will occur in the PHP parser, causing the program to fail to run normally.

PHP code example:

<?php
$name = 'Tom'; // 正确的变量名
$age : 20; // 错误的变量名，应该使用 = 而不是 : 
echo $Name; // 错误的变量名，应该为 $name
?>

<?php
$age; // 错误的变量定义方式
echo $age; // 错误的变量使用方式，因为 $age 并没有被赋值
?>

should be modified to:

<?php
$age = 20; // 给变量 $age 赋值
echo $age; // 正确的变量使用方式
?>

3. Missing brackets or semicolons

Sometimes brackets or semicolons Missing numbers can also cause parsing errors. For example, there are missing parentheses in function calls, missing semicolons at the end of statements, etc.

<?php
echo "Hello World" // 缺少分号 
?>

<?php
$sum = 1 + 2 * 3 // 缺少括号
echo $sum;
?>

should be modified to:

<?php
echo "Hello World"; // 添加分号
?>

<?php
$sum = (1 + 2) * 3; // 添加括号
echo $sum;
?>

4. Special character error

In the PHP language, some special The use of characters requires special attention. For example, single or double quotes are used in strings, inappropriate symbols are used in comments, etc.

PHP code example:

<?php
$name = 'Tom's'; // 错误的字符串语法，应该用双引号或者转义单引号 
?>

<?php
$sum = 1 + 2 /*注释不规范*/ 3; // 注释不规范
?>

should be modified to:

<?php
$name = "Tom's"; // 用双引号或者转义单引号 
?>

<?php
$sum = 1 + 2; /* 注释规范 */
$sum = $sum * 3;
?>
