Php Display_errors
PHP Errors to display? up vote 680 down vote favorite 204 I have checked my PHP ini file and display errors is set and also error reporting is E_ALL. I have restarted my apache web server. I have even put these lines at the top of my script and it doesn't even catch simple parse errors. For example, I declare variables with a "$" and php hide errors I don't close statements";". But all my scripts show a blank page on these errors, but i want to actually see the errors in my browser output. error_reporting(E_ALL); ini_set('display_errors', 1); What is left to do? php error-reporting share|improve this question edited Mar 9 at 7:16 Maninderpreet Singh 1,7111524 asked Jun 27 '09 at 19:09 Abs 13.4k68209356 3 I've yet to nail down exactly why this works sometimes and not others, but for anyone wanting to quickly toggle errors in a php script (or enable them via a $_REQUEST parameter) these two lines will work most of the time. –brandonscript Oct 28 '13 at 20:15 well you can see details of the error by enabling xdebug from php ini file. –jewelhuq Jan 13 at 10:14 add a comment| 13 Answers 13 active oldest votes up vote 1359 down vote accepted This always works for me: ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); However, this doesn't make PHP to show parse errors - the only way to show those errors is to modify your php.ini with this line: display_errors = on share|improve this answer edited Oct 23 '15 at 12:24 tleb 1,173721 answered Ja

13.4.1. Error Reporting Normally, when an error occurs in a PHP script, the error message is inserted into the script's output. If the error is fatal, the script execution stops. There are three levels of conditions: notices, warnings, and errors. A notice is a condition encountered while executing a script that could be an error but could also be encountered during normal execution (e.g., trying to access a variable that has not been set). A warning indicates a nonfatal error condition; typically, warnings are displayed when calling a function with invalid arguments. Scripts will continue executing after issuing a warning. An error indicates a fatal condition from which the script cannot recover. A parse error is a specific kind of error that occurs when a script is syntactically incorrect. All errors except parse errors are runtime errors. By default, all conditions except runtime notices are caught and displayed to the user. You can change this behavior globally in your php.ini file with the error_reporting option. You can also locally change the error-reporting behavior in a script using the error_reporting( ) function. With both the error_reporting option and the error_reporting( ) function, you specify the conditions that are caught and displayed by using the various bitwise operators to combine different constant values, as listed in Table 13-1. For example, this indicates all error-level options: (E_ERROR | E_PARSE | E_CORE_ERROR | E_COMPILE_ERROR | E_USER_ERROR) while this indicates all options except runtime notices: (E_ALL & ~E_NOTICE) If you set the track_errors option on in your php.ini file, a description of the current error is stored in $PHP_ERRORMSG. Table 13-1. Error-reporting values Value Meaning E_ERROR Runtime errors E_WARNING Runtime warnings E_PARSE Compile-time parse errors E_NOTICE Runtime notices E_CORE_ERROR Errors generated internally by PHP E_CORE_WARNING Warnings generated internally by PHP E_COMPILE_ERROR Errors generated internally by the Zend scripting engine E_COMPILE_WARNING Warnings generated internally by the Zend scripting engine E_USER_ERROR Runtime errors generated by a call to trigger_error( ) E_USER_WARNING Runtime warnings generated by a call to trigger_error( ) E_USER_NOTICE Runtime warnings generated by a call to trigger_error( ) E_ALL All of the above options 13.4.
