StringArray PHP ActiveX Reference Documentation

StringArray

Current Version: 10.1.2

Class/object for managing and manipulating collections of strings. Contains an ordered collection of strings.

Important: The Chilkat StringTable class is a better choice for a large number of strings.

Object Creation

Chilkat v10.0.0 or greater:
$obj = new COM("Chilkat.StringArray");
Chilkat v9.5.0.*:
$obj = new COM("Chilkat_9_5_0.StringArray");

Properties

Count
int Count (read-only)

The number of strings contained within the object's internal array (i.e. ordered collection).

Important: This is an object that contains a collection of strings. Although the class/object name includes the word "Array", it should not be confused with an array in the sense of the primitive array type used in a given programming language.

top
Crlf
bool Crlf

If true, strings are always automatically converted to use CRLF line endings. If false, strings are automatically converted to use bare LF line endings.

top
DebugLogFilePath
string DebugLogFilePath

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
LastBinaryResult
VARIANT LastBinaryResult (read-only)

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to true. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

top
LastErrorHtml
string LastErrorHtml (read-only)

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
string LastErrorText (read-only)

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
string LastErrorXml (read-only)

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
bool LastMethodSuccess

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

top
LastStringResult
string LastStringResult (read-only)

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

top
LastStringResultLen
int LastStringResultLen (read-only)

The length, in characters, of the string contained in the LastStringResult property.

top
Length
int Length (read-only)

The number of strings contained within the internal collection. (Identical to the Count property.)

top
Trim
bool Trim

If true, whitespace, including carriage-returns and linefeeds, are automatically removed from the beginning and end of a string when added to the collection.

top
Unique
bool Unique

If true, then duplicates are not allowed. When an attempt is made to insert a string that already exists, the duplicate insertion is silently suppressed and no error is returned. The default value is false.

top
VerboseLogging
bool VerboseLogging

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
string Version (read-only)

Version of the component/library, such as "10.1.0"

Methods

Append
bool Append(string str)

Appends a string to the end of the internal ordered collection.

Returns true for success, false for failure.

top
AppendSerialized
bool AppendSerialized(string encodedStr)

Appends multiple strings to the end of the internal ordered collection. The encodedStr is what is returned from the Serialize method (see below).

Returns true for success, false for failure.

top
Clear
void Clear()

Remove all strings from the internal collection.

top
Contains
bool Contains(string str)

Returns true if the string is present in the internal collection. The string comparisons are case sensitive.

top
Find
int Find(string findStr, int startIndex)

Finds the index of the first string equal to findStr. The search begins at startIndex. If the string is not found, -1 is returned. The first string in the array is at index 0.

top
FindFirstMatch
int FindFirstMatch(string matchPattern, int startIndex)

Finds the first string that matches the matchPattern. The search begins at startIndex. If the string is not found, -1 is returned. The first string in the array is at index 0.

The matchPattern may contain zero or more asterisk chars, each of which matches 0 or more of any character.

top
GetString
string GetString(int index)

Returns the string at an indexed location within the internal collection. The first string is located at index 0.

Returns null on failure

top
InsertAt
void InsertAt(int index, string str)

Inserts a string into the internal collection at a specified index. Using index 0 will insert at the beginning.

top
LastString
string LastString()

Returns the last string in the internal collection.

Returns null on failure

top
LoadFromFile
bool LoadFromFile(string path)

Loads strings from a file (one per line) into the internal collection. It is assumed the file contains ANSI strings. To load from a file containing non-ANSI strings (such as utf-8), call LoadFromFile2 instead.

Note: This method appends the strings in path to the existing collection of strings contained in this object.

Returns true for success, false for failure.

top
LoadFromFile2
bool LoadFromFile2(string path, string charset)

Loads strings from a file (one per line) into the internal collection. The charset specifies the character encoding (such as utf-8) of the strings contained in the file.

Note: This method appends the strings in path to the existing collection of strings contained in this object.

Returns true for success, false for failure.

top
LoadFromText
void LoadFromText(string str)

Loads strings from an in-memory string (one per line) into the internal collection.

Note: This method appends the strings in str to the existing collection of strings contained in this object.

top
LoadTaskResult
bool LoadTaskResult(Chilkat.Task task)
Introduced in version 9.5.0.52

Loads the string collection from a completed asynchronous task.

Returns true for success, false for failure.

top
Pop
