How to solve PHP error: syntax error, unexpected T_VARIABLE symbol?

Introduction:
In PHP development, we sometimes encounter syntax errors. One of the common errors is "Parse error: syntax error, unexpected T_VARIABLE", unexpected T_VARIABLE symbol. This error usually occurs due to some syntax error in the code. This article will introduce the cause and solution of this error, and provide some code examples to help readers better understand.

1. Error causes and solutions:
   This error is usually caused by missing a semicolon (;) or incorrectly using the variable symbol ($) in the PHP code. Below we will explain each of these two situations and their solutions.

1.1. Missing semicolon (;):
In PHP, a semicolon is used to end a statement. If a semicolon is missing at the end of a line of code, it will result in "Parse error: syntax error, unexpected T_VARIABLE" error. For example:

<?php
    $name = "John"
    echo "Hello, ".$name;
?>

In the above code, the second line is missing a semicolon, causing the error. To solve this problem, just add a semicolon at the end of the second line:

<?php
    $name = "John";
    echo "Hello, ".$name;
?>

1.2. Incorrect use of the variable symbol ($):
In PHP, variables start with the $ symbol , and cannot contain special characters. If we add extra characters before and after the variable name or miss the $ symbol, it will also cause "Parse error: syntax error, unexpected T_VARIABLE" error. For example:

<?php
    name = "John";
    echo "Hello, ".$name;
?>

In the above code, the second line is missing the $ symbol, causing an error. To solve this problem, just add the $ symbol before the variable name in the second line:

<?php
    $name = "John";
    echo "Hello, ".$name;
?>

2. Code example:
   The following are some common "Parse error: syntax error, unexpected T_VARIABLE" error examples and provide corresponding solutions.

2.1. Example 1:
Error code:

<?php
    $name = "John";
    echo "Hello, ".$nane;
?>

Solution:
Change $nane to $name in the third line.

<?php
    $name = "John";
    echo "Hello, ".$name;
?>

2.2. Example 2:
Error code:

<?php
    $x = $y + 2
    echo $x;
?>

Solution:
Just add a semicolon at the end of the second line.

<?php
    $x = $y + 2;
    echo $x;
?>
