PHP Catch Error

• Suppress error output

error_reporting (0);

• Setting the error handler

Set_error_handler (' ErrorHandler ');

• Functions that run at the end of the script

Register_shutdown_function (' Fatalerrorhandler ');

• Error handling

/** * @param int    $err _no      Error code * @param string $err _msg  Error message * @param string $err _file    Error file * @param int
   $err _line     Error Line number * @return string */function errorhandler ($err _no = 0, $err _msg = ', $err _file = ', $err _line = 0) { c6/> $log = ['        ['. Date (' y-m-d h-i-s '). '] ',        ' | ',        $err _no,        ' | ',        $err _msg,        ' | ',        $err _ File,        ' | ',        $err _line    ];    $log _path = './test.txt ';    Error_log (Implode (", $log)." \ r \ n ", 3, $log _path);}

• Catching fatal errors

function Fatalerrorhandler () {    $e = Error_get_last ();    Var_export ($e);    Switch ($e [' type ']) {case        1:            errorhandler ($e [' type '], $e [' message '], $e [' file '], $e [' line ']);            break;    }}

Class democlass_1{public    function Index ()    {        //A warning error occurred here, departure ErrorHandler        echo $undefinedVarible;    }}

• Here is a warning error, captured by ErrorHandler

$demo _1 = new Democlass_1 (); $demo _1->index ();

• A fatal error occurred and the script stopped running triggering Fatalerrorhandler

$demo _2 = new Democlass_2 (); $demo _2->index ();

Output after opening test.txt:
