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。

/* 继承的属性 */

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'");
