# php_check_syntax

(PHP 5)

php_check_syntax -- Check the PHP syntax of (and execute) the specified file

## Descrição

bool php_check_syntax ( string file_name [, string &error_message] )

The php_check_syntax() function performs a syntax (lint) check on the specified filename testing for scripting errors. This is similar to using php -l from the commandline except php_check_syntax() will execute (but not output) the checked file_name. For example, if a function is defined in file_name, this defined function will be available to the file that executed php_check_syntax(), but output from file_name will be suppressed.

## Lista de parâmetros

file_name

  The name of the file being checked.

error_message

  If the error_message parameter is used, it will contain the error message generated by the syntax check. error_message is passed by reference.

## Valores Retornados

Returns `TRUE` if the lint check passed, and `FALSE` if the link check failed or if file_name cannot be opened.

## Histórico

## Exemplos

Exemplo 1. php_check_syntax() example
`<?php $error_message = ""; $filename = "./tests.php"; if(!php_check_syntax($filename, $error_message)) { printf("Errors were found in the file %s:\n\n%s\n", $filename, $error_message); } else { printf("The file %s contained no syntax errors.", $filename); } ?>`
O exemplo acima irá imprimir algo similar a:
    Errors were found in the file ./tests.php:
