ParseError

    (PHP 7, PHP 8)

    简介

    ParseError 当解析 PHP 代码时发生错误时抛出，比如当 eval()被调用出错时。

    注意: 从 PHP 7.3.0 开始，ParseError 继承自 CompileError。之前的版本，则继承自 Error。

    类摘要

    protected int $code;
    protected string $file = "";
    protected int $line;
    private array $trace = [];
    private ?Throwable $previous = null;
    /* 继承的方法 */
    public Error::__construct(string $message = "", int $code = 0, ?Throwable $previous = null)
    final public Error::getMessage(): string
    final public Error::getPrevious(): ?Throwable
    final public Error::getCode(): int
    final public Error::getFile(): string
    final public Error::getLine(): int

    The priority of Parse Error should be higher than that of Fatal Error,Parse Error, which has the highest priority among all PHP exceptions. See the following example:
    <?php
    error_reporting    (E_ALL);
    test()
    //System output a parse error
    ?>
    <?php
    error_reporting    (E_WARNING);
    test()
    //System output a parse error
    ?>
    <?php
    error_reporting    (E_ERROR);
    test()
    //System output a parse error
    ?>
    <?php
    error_reporting    (E_PARSE);
    test()
    //System output a parse error
    ?>

    <?php
    /*
    * The function eval() evaluate his argument as an instruction PHP
    * Then the argument must respect the standar of PHP codage
    * In this example the semicolon are missign
    */

    try{

    eval(    "echo 'toto' echo 'tata'");

    }catch(    ParseError $p){

    echo     $p->getMessage();
    }

    /*
    * If you run this code the result is different of the result of above code
    * PHP will output the standar parse Error: syntax error, ....
    *

    eval("echo 'toto' echo 'tata'");
