readTextBlock.php

Read a block of text from file delimited by string as a record delimited

The delimiter can either be prefixed, suffixed - or removed

Example

Given the data:

01
02
###
04
05
###
07
08

$delimiter  = '###';
$direction  = -1;    // Default: prefixed
$fp = @fopen("readTextBlock.txt", "r");
while( $record = get_text_block( $fp, $delimiter, $direction ) )  // Get each record
{
    echo "[$record]\n";
}
fclose($fp);

Output:

Direction: -1 // Suffix

Delimiter will be at the end of record (Suffixed)

[01     02      ###     ]
[04     05      ###     ]
[07     08      ]

Direction: 0 // None

Delimiter will be removed from record

[01     02      ]
[04     05      ]
[07     08      ]

Direction: 1 // Prefix

Delimiter will be at the start of record (Prefixed)

[01     02      ]
[###    04      05      ]
[###    07      08      ]
