Parser

class Parser

Parser parses YAML strings to convert them to PHP arrays.

Constants

BLOCK_SCALAR_HEADER_PATTERN
FOLDED_SCALAR_PATTERN

Methods

__construct(int $offset, int|null $totalNumberOfLines = null, array $skippedLineNumbers = array())
mixed parse(string $value, bool $exceptionOnInvalidType = false, bool $objectSupport = false, bool $objectForMap = false)

Parses a YAML string to a PHP value.

static preg_match($pattern, $subject, $matches = null, $flags, $offset)

A local wrapper for preg_match which will throw a ParseException if there is an internal error in the PCRE engine.

Details

__construct(int $offset, int|null $totalNumberOfLines = null, array $skippedLineNumbers = array())

Parameters

int $offset The offset of YAML document (used for line numbers in error messages)
int|null $totalNumberOfLines The overall number of lines being parsed
array $skippedLineNumbers Number of comment lines that have been skipped by the parser

mixed parse(string $value, bool $exceptionOnInvalidType = false, bool $objectSupport = false, bool $objectForMap = false)

Parses a YAML string to a PHP value.

Parameters

string $value A YAML string
bool $exceptionOnInvalidType true if an exception must be thrown on invalid types (a PHP resource or object), false otherwise
bool $objectSupport true if object support is enabled, false otherwise
bool $objectForMap true if maps should return a stdClass instead of array()

Return Value

mixed A PHP value

Exceptions

ParseException If the YAML is not valid

static preg_match($pattern, $subject, $matches = null, $flags, $offset)

A local wrapper for preg_match which will throw a ParseException if there is an internal error in the PCRE engine.

This avoids us needing to check for "false" every time PCRE is used in the YAML engine

Parameters

$pattern
$subject
$matches
$flags
$offset

Exceptions

ParseException on a PCRE internal error
