The correct way would be to set the variable before using it, even if it's just an empty string like $counter = 0; foreach ($items as $item) { // do something share|improve this answer edited Apr 27 '15 at 2:19 community wiki 4 revsmario add a comment| up vote 8 down vote Unexpected T_IS_EQUAL Unexpected T_IS_GREATER_OR_EQUAL Unexpected T_IS_IDENTICAL Unexpected T_IS_NOT_EQUAL Unexpected T_IS_NOT_IDENTICAL If you have error logging enabled, you will find the concrete error message in your error log. If an exception is not caught, a PHP Fatal Error will be issued with an "Uncaught Exception ...

Multiple catch blocks can be used to catch different classes of exceptions. Invisible Unicode characters A most hideous cause for syntax errors are Unicode symbols, such as the non-breaking space.

In the class section you can only list property initializations and method sections. http://php.net/manual/en/function.define.php

Define Php

The following error types cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICT raised in the file where set_error_handler() is called. value The value of the constant. Execution of the script is not halted. 4 E_PARSE (integer) Compile-time parse errors. Check that mysql.default_user= and mysql.default_password= have meaningful values.

Nobody can guess your setup). For runaway strings and misplaced operators this is usually where you find the culprit. Therefore it may take looking through a few more pages before you find something relevant. Php Error Types Can you share your experience on pros/cons; is your favorite Eclipse/PDT or..? –mario Aug 12 '13 at 20:31 @mario I think you are really deep into the topic so

Again note that PHP 7 only allows var $xy = 1 + 2 +3; constant expressions there. Php Const A trailing ; is often redundant for the last statement in any PHP script. share|improve this answer edited Jan 5 '15 at 6:42 community wiki 12 revs, 7 users 43%xdazz 2 Just a note. http://php.net/manual/en/features.file-upload.errors.php This parameter decides whether the function returns a stdclass instead of an associative array. –Hugo Zink Jan 22 at 8:16 add a comment| up vote 15 down vote Warning: Illegal string

On a 1s-complement system -1 would not set E_ERROR. Defined first order condtion of Lagrangian Is this alternate history plausible? (Hard Sci-Fi, Realistic History) Why do units (from physics) behave like numbers? A typical example would be a template file like this: My Page ... For example: $value = @(2 / 0); But, like with any warning, the best approach would be to track down the cause of the warning and resolve it.

Php Const

This example is checking * if the string 'TEST' is the name of a constant named TEST */ if (defined('TEST')) { echo TEST; } share|improve this answer answered May 4 '11 http://php.net/manual/en/errorfunc.constants.php Copyright 1999-2016 by Refsnes Data. Define Php In particular when function code blocks got closed too early. Define Continual The parser complains about the contained single quoted 'string', because it usually expects a literal identifier / key there.

Also known as the White Page Of Death or White Screen Of Death. You carry these resources around and pass them to different functions for which such a resource means something. The PHP documentation recommends this syntax for complex variables. Strict Standards: Non-static method [::] should not be called statically Also see Reference - What does this symbol mean in PHP? Php Error Codes List

If you see string colorization extend too far or too short, then you have found an unescaped or missing closing " or ' string marker. And since the parser can't make sense of two subsequent literals/values without an expression operator in between, that'll be a parser failure. Follow any coding style. UPLOAD_ERR_EXTENSION Value: 8; A PHP extension stopped the file upload.

Depending on your application, it may be easier to shift your paradigm a bit and use the following method instead, declaring your constants as variables first:


Sometimes the wrong file or directory names are used, the fix is then to use the right ones.

So please take the time to follow the basic steps, before posting syntax fixing requests. This can be easily solved by using a full path or magic constants like __DIR__ or dirname(__FILE__): include __DIR__ . '/inc/globals.inc.php'; or: require dirname(__FILE__) . '/inc/globals.inc.php'; Ensuring the right path is An example of what not to do (the "Bad Idea"): $query = "UPDATE `posts` SET my_text='{$_POST['text']}' WHERE id={$_GET['id']}"; mysqli_query($db, $query); This code could be included in a page with a form Define Sustained This error will not cause an exception, therefore, some developers will occasionally suppress the warning by adding the error suppression operator @ before the expression.

Don't use PHPs reserved keywords as identifiers for functions / methods, classes or constants. If the function was introduced in a newer version of PHP from what you are using, you may find links to alternative implementations in the manual or its comment section. Parens grouping In particular for if statements with multiple comparisons you must take care to correctly count opening and closing parenthesis: ⇓ if (($foo < 7) && $bar) > 5 || This is actually more a case of blacklisted expressions (due to equivalent operator associativity).

But maybe I've misread your question. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count). When a class or a function is declared in PHP, it is immutable, and cannot later be declared with a new value. Parse errors should only be generated by the parser. 4 4 E_NOTICE Run-time notices.

Older installations only support array(). $php53 = array(1, 2, 3); $php54 = [1, 2, 3]; ⇑ Array function result dereferencing is likewise not avaiable for older PHP versions: $result = get_whatever()["key"]; UPLOAD_ERR_PARTIAL Value: 3; The uploaded file was only partially uploaded. Last statement in a code block It can happen for any unterminated expression. If the error-handler function returns, script execution will continue with the next statement after the one that caused an error.

CONSTANT and Constant represent different values. Also see PHP code is not being executed (i can see it on source code of page) share|improve this answer edited Feb 5 '15 at 5:07 community wiki 4 revs, 2 Which might be enlightening as to what the syntax problem is. Whitespace is your friend.

The parser will then concretise the line number for parsing errors. To actually run your PHP scripts, you need: a web server which executes your script to set the file extension to .php, otherwise the web server won't interpret it as such*
